Arcade Stick Parts Guide: Best Buttons, Levers, Gates, and PCBs for Upgrades

Overview

If you are searching for an arcade stick parts guide, it usually means one of three things. You want a better feel than your stock parts provide, you want broader platform compatibility, or you want to repair and refresh a stick you already like. In all three cases, the best upgrade path starts with understanding which part changes what.

Buttons affect actuation feel, sound, travel, and return speed. Levers affect movement style, resistance, engage distance, throw, and how easy it is to find diagonals. Gates shape the edge feel of directional input and can slightly change how controlled or loose a lever feels. PCBs determine what systems your stick can talk to, which inputs are supported, and how cleanly your internal wiring comes together.

That sounds straightforward, but many buyers run into the same problem: popular parts are often discussed as if there is one objectively best setup. In practice, there is not. The best arcade buttons for a light-touch player may feel too soft to someone who prefers firmer feedback. A well-liked Japanese lever may feel perfect for one fighting game and slightly vague for another. A strong PCB choice for PC-only use may not be the right choice if you also need console support.

For most players, a smart upgrade plan looks like this:

• Change one major variable at a time.
• Confirm physical compatibility before ordering.
• Prioritize feel upgrades before platform-expansion upgrades if your current stick already works where you play.
• Keep your stock parts until you know the new setup is right.

How to compare options

The easiest way to waste money on parts is to shop by brand name alone. Well-known names matter, but only after you narrow down the practical requirements of your build. Before comparing Sanwa vs Seimitsu, or choosing a fight stick PCB, work through these five filters.

1. Start with your case and mounting layout

Not every enclosure accepts every lever or button style without effort. Some cases have limited internal depth. Others support only certain mounting plates, button diameters, or connector orientations. Before buying anything, check:

• Button hole size, commonly 24 mm or 30 mm for action buttons
• Whether your panel is metal, plastic, or layered acrylic/wood
• Available internal clearance for the lever body and harness
• Whether your current wiring uses quick disconnects, soldered leads, or a prebuilt harness

If you are shopping for a first stick instead of parts alone, a budget model with a straightforward layout may be the better starting point. Our guide to Best Budget Arcade Sticks Under $100 That Are Actually Worth Buying is useful for that route.

2. Decide what you are trying to improve

Be specific. “I want a better stick” is too vague. Instead, identify the exact issue:

• Buttons feel mushy or too loud
• Lever returns too loosely or too stiffly
• Diagonals are hard to hit consistently
• The stick only works on one platform
• The stock PCB lacks convenient wiring or tournament features

Once you know the problem, the part category becomes clearer. A missed-input problem may be a lever, gate, or switch issue rather than a button problem. A compatibility problem is rarely solved by changing the lever or buttons; that usually points to PCB or converter choices.

3. Separate feel from compatibility

This is one of the most useful distinctions in any arcade stick parts guide. Buttons, levers, springs, actuators, and gates are mostly feel upgrades. PCBs and converters are compatibility upgrades. Do not mix those shopping goals unless you are intentionally rebuilding the entire stick at once.

If cross-platform use is part of your plan, read Arcade Stick Compatibility Guide: PC, PS5, Xbox, Switch, and Retro Consoles and Brook Wingman and Converter Guide: Which Arcade Sticks Work With Which Consoles before opening your case.

4. Compare maintenance and install difficulty

Some parts are effectively drop-in. Others require rewiring, plate changes, drilling, or firmware setup. In general:

• Snap-in buttons are easier in thinner panels.
• Screw-in buttons can be more secure but need enough clearance underneath.
• Common Japanese levers often have broad community support and simpler replacement paths.
• PCBs can range from tidy harness-based installs to full custom rewiring jobs.

If you want the lowest-risk first mod, start with buttons. If you want the most dramatic feel change, start with the lever.

5. Think in terms of the full build, not isolated parts

An arcade stick is a system. A very light button paired with a very stiff lever can feel oddly mismatched. A premium PCB inside a cramped, awkward case may not solve the overall user experience. When comparing options, ask whether the new part supports the way the rest of the setup works.

Feature-by-feature breakdown

This section is the practical core of the comparison. If you are weighing the best joystick lever, choosing your first button swap, or trying to understand how a fight stick PCB affects the rest of the build, use these categories to compare parts in a structured way.

Buttons: feel first, brand second

The best arcade buttons are not simply the most famous ones. They are the ones that match your preferred force, travel, sound, and speed. Two players can use the same game, the same character, and the same stick shell and still prefer completely different button behavior.

When comparing buttons, focus on:

• Actuation feel: light and effortless versus firm and deliberate
• Travel: short movement can feel quick; deeper movement can feel more controlled
• Return: how quickly and cleanly the button resets after a press
• Sound: some buttons are bright and sharp; others are quieter and lower in pitch
• Mounting style: snap-in versus screw-in
• Panel compatibility: especially important on thicker custom cases

In broad terms, Sanwa-style buttons are often chosen by players who want a light, fast press with a familiar arcade feel. Seimitsu-style buttons are often considered by players who want a slightly different resistance profile and a more deliberate response. That is why “Sanwa vs Seimitsu” remains a useful comparison, but only as a starting point. The real question is which feel helps you play with more confidence.

If your current buttons work reliably but feel unremarkable, this is often the easiest upgrade with the most immediate day-to-day payoff.

Levers: the biggest change in control feel

If buttons shape your attacks, the lever shapes your movement language. A lever swap can change how your stick feels more than any other single mod.

Here is what to compare:

• Engage distance: how far the shaft moves before an input registers
• Throw distance: how far the shaft travels before it reaches the gate edge
• Spring tension: lighter feels more relaxed; heavier can feel more stable and forceful
• Pivot feel: affects smoothness during circular and diagonal motion
• Handle type: ball top, bat top, or alternate grip preferences
• Mounting plate and shaft height: critical for proper fit and expected feel

Players looking for a classic Japanese arcade style often start with the most common lever families because they are well-documented and easy to support with replacement parts. Others prefer a firmer or more compact feel that changes how corners and diagonals register under pressure. If you play a mix of 2D fighters, older arcade games, and action titles, your ideal lever may not be the same as someone focused only on modern tournament fighters.

A useful rule: if your complaint is directional precision, do not buy a new stick body first. Try a lever, spring, or actuator change before replacing the entire controller.

Gates: a small part that changes confidence

Gates are often overpromised and underexplained. They do not transform your fundamentals, but they do change how the lever feels at the edge of movement. For some players, that edge feel makes directional consistency easier.

Common comparisons usually revolve around:

• Square gates: a familiar standard for many Japanese lever setups
• Octagonal gates: more edge points, often preferred by players who want stronger directional landmarks
• Circular gates: less common in many standard builds, but sometimes preferred for specific feel goals

The right choice depends less on internet consensus and more on how you reference movement. Some players like to feel corners clearly. Others find extra edge points distracting. If you are curious, gates are a relatively low-cost experiment compared with a full lever replacement.

That said, if your diagonals feel inconsistent, the gate may not be the only issue. Engage distance, actuator size, and switch feel can matter just as much.

PCBs: the control center of the build

A fight stick PCB matters for two reasons: platform support and wiring logic. If your stock board already works on all the systems you use, replacing it may not improve feel at all. But if you need multi-platform support, cleaner internals, or more flexible button mapping, the PCB becomes one of the most important upgrade decisions.

Compare PCBs using these questions:

• Which platforms do you need to support now?
• Do you need native support or are you comfortable using a converter?
• How easy is the wiring for your current buttons and lever?
• Do you want screw terminals, harness support, or both?
• Will your case easily accommodate the board and cable routing?
• Do you need features such as touchpad support, tournament lock behavior, or firmware updating?

For PC-only players, your options may be broader and simpler. For console players, especially those moving across multiple generations or brands, PCB selection becomes more careful. In some cases, keeping your current board and using a converter may be cleaner than a full internal replacement. In others, a fresh PCB gives you a more elegant long-term setup.

Secondary parts that are worth your attention

Buttons, levers, gates, and PCBs get the headlines, but smaller parts often complete the experience:

• Springs: a subtle but meaningful way to change resistance
• Actuators: can alter engage feel and responsiveness
• Wiring harnesses: reduce install frustration and improve internal cleanliness
• Dust washers and shaft covers: mostly cosmetic, but useful in some builds
• USB cable solutions: important for portability and durability

These are best treated as finishing touches after you solve the larger questions of feel and compatibility.

Best fit by scenario

If you are not sure where to start, these common scenarios can narrow the decision.

You like your stick, but the buttons feel cheap

Start with a button swap. This is usually the safest and most immediately satisfying upgrade. Choose based on actuation weight, sound profile, and mounting compatibility rather than online popularity alone.

You miss diagonals or dislike the movement feel

Start with the lever, not the PCB. Compare spring tension, engage, throw, and mounting fit. If the basic lever architecture is close to what you want, a spring or actuator change may be enough.

You want stronger directional landmarks

Try a gate change after confirming the lever itself is otherwise suitable. Gates are best viewed as tuning parts, not miracle fixes.

You need the stick to work on more platforms

Look at PCBs and converters first. Read compatibility guides before buying internal parts that do not address the real problem. The articles on arcade stick compatibility and Brook Wingman converters are the most relevant next steps.

You are building a stick on a budget

Prioritize the part you touch most. For many players, that is the lever. For others, it is the buttons. Avoid replacing everything at once unless the stock internals are clearly holding the build back.

You are buying gifts for a fighting game player

Do not guess on feel-sensitive parts unless you know their preferences. Safer gifts include spare buttons in their preferred size, simple accessories, or a gift budget toward a part they can choose themselves. If you are still shopping broadly, our related guides on accessories and mod-friendly sticks may be a better fit than a blind parts purchase.

You are considering a full rebuild

Make a compatibility checklist before ordering: case depth, button hole size, lever mount, cable routing, PCB mounting points, and platform needs. A full rebuild can be satisfying, but it becomes much easier when every part is selected as part of a single plan.

When to revisit

The best time to revisit your parts setup is not only when something breaks. Good arcade stick builds evolve as your games, platforms, and preferences change. Use these moments as your update triggers.

• When pricing changes: a part that felt hard to justify may become a sensible upgrade later.
• When a new revision appears: small design updates can improve installation, fit, or long-term reliability.
• When you change platforms: moving from PC-only to console play often makes PCB or converter choices more important.
• When you change games: a setup you liked for one genre may not feel ideal for another.
• When your case changes: a new enclosure can open up lever and button options that were previously unavailable.
• When your preferences become more specific: once you can clearly describe what feels off, better upgrade choices follow.

A practical routine is to keep a simple mod log. Write down your current parts, what you changed, what improved, and what still feels unresolved. That record makes future upgrades much easier and helps you avoid buying the same kind of part twice for the same reason.

If you are actively shopping rather than planning, bookmark deal-focused and comparison guides too. Our roundup of Best Arcade Stick Deals Today: Budget, Mid-Range, and Premium Picks can help when a full replacement starts to make more sense than another round of upgrades.

The short version is this: buy arcade stick parts with a diagnosis, not a mood. Compare feel, fit, and compatibility in that order. Start with the part most closely tied to your actual problem. And revisit your setup whenever new hardware, new revisions, or new platform needs change the equation. That is how a stick becomes not just customized, but genuinely well tuned.
