5-Pin vs. 3-Pin Switches: Which Are Better for Mechanical Keyboards?

When it comes to building or customizing a mechanical keyboard, one of the key decisions enthusiasts face is choosing between 5-pin and 3-pin switches. While both types serve the same primary function, there are notable differences that can influence your keyboard's performance and customization options. Let's delve into the debate of 5-pin vs. 3-pin switches to help you make an informed decision.

What Are 5-Pin and 3-Pin Switches?

• 5-Pin Switches: These switches have five metal pins extending from the bottom. Two of these pins are for the switch's electrical function, while the other three are for added stability when mounted on the keyboard PCB (Printed Circuit Board).

• 3-Pin Switches: Conversely, 3-pin switches have only three metal pins, two for the electrical function and one for mechanical stability. They lack the two additional plastic guide pins found on 5-pin switches.

Key Differences

• Stability: The additional two plastic guide pins on 5-pin switches offer improved stability compared to 3-pin switches. This can result in a more secure fit when soldered to the PCB, reducing wobble and enhancing overall typing feel.
• Compatibility: 5-pin switches are compatible with both PCBs designed for 5-pin and 3-pin switches, thanks to the extra plastic guide pins that can be clipped off if not needed. 3-pin switches, however, are only compatible with PCBs designed specifically for 3-pin switches.
• Customization: For keyboard enthusiasts looking to customize their switches with aftermarket parts, 5-pin switches offer more flexibility. They can easily accommodate custom springs, stems, and housings designed for 5-pin configurations.

Which Is Better?

• For Most Users: For most users, the differences between 5-pin and 3-pin switches might not be noticeable in everyday typing or gaming. 3-pin switches are simpler to work with and are generally more than adequate for most builds.
• For Enthusiasts: Enthusiasts who prioritize maximum stability and customization options might prefer 5-pin switches. The added stability can be particularly beneficial for heavier typists or those who prefer a more rigid typing experience.

Final Thoughts

In conclusion, both 5-pin and 3-pin switches have their merits, and the choice between them largely depends on your priorities and level of customization. For most users, 3-pin switches offer simplicity and compatibility with a wide range of PCBs. However, if you value maximum stability and customization options, 5-pin switches might be the way to go.

Ultimately, the best switch for your mechanical keyboard is the one that feels right to you. Whether you opt for 5-pin or 3-pin switches, the most important thing is to choose switches that suit your typing style and preferences.
