Can 3 Pin Switches Work with 5 Pin PCB?

The world of mechanical keyboards is intricate and nuanced, filled with jargon that can feel overwhelming for beginners. If you’ve ever found yourself wondering about the difference between 3 pin and 5 pin switches or how they interact with PCBs (Printed Circuit Boards), you’re not alone!

Understanding Plate-Mounted vs PCB-Mounted Keyboards

Before we deep-dive into the nitty-gritty of pins and switches, let’s familiarize ourselves with two major mounting styles: Plate-mounted and PCB-mounted keyboards. (Learn more about them here).

Plate-mounted keyboards typically come with three pins on each switch – two metal ones that facilitate the functioning of the switch and a central circular knob. They offer a stable feel when typing due to less side-to-side movement and often have a longer lifespan. However, these benefits come at a higher cost due to additional parts and assembly required.

PCB-mounted keyboards, on the other hand, are fitted with switches that have five pins. Apart from the two functional metal pins and the central circular knob, these switches also feature two tiny plastic legs for added stability.

Can 3 Pin Switches Work with 5 Pin PCB?

The answer is yes! Your 3 pin switch can indeed be adapted to fit into your 5 pin-compatible circuit board. This can be achieved using special adapters that bridge the gap between different sizes or by clipping off those extra legs on your switch using hobby clippers.

It’s like playing Tetris but instead of falling blocks, you’re dealing with keyboard components!

Tips for Ensuring Secure Connections

When connecting your three-pin switch to a five-pin PCB, it’s crucial to ensure all connections are secure. Unconnected pins can cause issues down the line.

Consider using high-quality materials like gold or silver plated pins and connectors as they provide an excellent connection without compromising signal integrity. It’s like using top-tier armor in an RPG game – sure, you could get by with lesser gear, but why risk it?

Always test your connections before powering up your circuits to verify everything runs smoothly – think of it as a quick save before entering a boss battle!

Do You Always Need An Adapter?

Not necessarily! While an adapter can provide a more reliable connection – serving as an ideal bridge between your three-pin switch and five-pin PCB – it’s not always mandatory. Just remember that without those extra plastic legs (or an adapter), your switches might lack some stability.

Advantages of Using an Adapter

While using an adapter isn’t always necessary when connecting 3 pin switches with 5 pin PCBs, it can offer certain advantages. An adapter can help to bridge the size gap and provide a secure connection, minimizing any instability or wobbling issues that might arise due to the missing extra legs. It’s like having an additional support character in your team during tough gaming sessions – not always needed but definitely handy under specific circumstances!

For those new to mechanical keyboards, installing switches into PCBs might seem like uncharted territory. Fear not! Guiding pins are included with most switches for easier installation on the PCB – simply align these pins with corresponding holes on your circuit board and apply gentle pressure until the switch is firmly seated.

Understanding the Anatomy of a Switch

Diving deeper into the world of keyboard switches, it’s essential to understand their anatomy. The basic structure of a switch consists of four pins that hold it together – two metal ones that enable the switch to function, two plastic ones that ensure stability on a PCB-mounted switch, and a central “pin” that more closely resembles a sizable round knob. The main difference between 3 pin vs 5 pin switch connector lies in the legs protruding out from its bottom.


Can I use my old three-pin switches with my new five-pin PCB?

Absolutely! With some minor modifications such as clipping off extra legs or using special adapters, you can easily fit your three-pin switches onto your five-pin PCB.

Is there any distinct advantage of either three-pin or five-pin over each other?

There isn’t necessarily a clear advantage of one over another. It’s more about personal preference depending on whether you prioritize cost-efficiency or stability.

What should I do if my connections aren’t working properly after installation?

Ensure all pins are securely fitted into their corresponding slots in the PCB and no pins are left unconnected. If issues persist even after checking connections, consider seeking professional help.

Do I always need high-quality materials like gold or silver plated pins?

While not mandatory, using such materials can ensure better connection reliability and longevity for your keyboard setup.

Which One Is Better: Three-Pin or Five-Pin?

This is akin to asking if cake is better than ice cream – both have their merits depending on personal preference! (Learn more about best keyboard switches here). In this case, it boils down to whether you prioritize stability over cost-efficiency (and vice versa).

In conclusion, yes – three-pin switches can work in harmony with five-pin PCBs. So don’t let those pesky extra holes intimidate you; rather view them as opportunities for customization and optimization! After all, isn’t that what building mechanical keyboards is all about?
