Do Alps Switches Share the Same PCB with MX Switches? A Comprehensive Guide

Introduction

Hey there, readers! Welcome to our in-depth exploration into the compatibility between Alps switches and MX switches. From their origins to their physical characteristics, we’ll dive into everything you need to know about these two popular switch types to answer the burning question: do they share the same PCB?

The Anatomy of a Keyboard Switch

MX Switches: A Contemporary Classic

MX switches have dominated the mechanical keyboard scene for decades. These switches are known for their square-shaped stems with cross-shaped actuation points. They come in various colors, each indicating a different force required for actuation, giving users a wide range of options to suit their typing preferences.

Alps Switches: A Retro Delight

Alps switches, on the other hand, are a blast from the past. Originating in the 1980s, these switches feature a distinctive rounded stem and a tactile "bump" when pressed. They were commonly found in keyboards from brands like IBM and Apple in their earlier days.

Compatibility Conundrum

PCB Layout: The Foundation of Compatibility

The PCB (printed circuit board) is the backbone of any keyboard. It houses the electrical circuitry that connects the switches to the computer. The layout of the PCB, including the shape and placement of switch holes, determines which types of switches can be used.

Alps vs. MX: A Physical Mismatch

So, do Alps switches share the same PCB with MX switches? In short, no. The physical dimensions of Alps and MX switches are different. The rounded stem of Alps switches won’t fit into the square-shaped holes designed for MX switches. Additionally, the pinouts on Alps switches are arranged differently from those on MX switches.

Adapters: A Bridge Between Worlds

Despite their physical differences, there are ways to mount Alps switches on MX-compatible PCBs. Adapters are small devices that convert the round stem of Alps switches to fit into MX switch holes. While adapters may work in some cases, it’s important to note that they may introduce compatibility issues or affect switch performance.

A Tale of Two Keyboards

Alps-Based Keyboards: A Nostalgic Charm

Alps-based keyboards are a favorite among enthusiasts who cherish the classic feel and tactile feedback of Alps switches. These keyboards have a distinctive "clicky" sound and a satisfying bump when pressed, making them a joy to type on.

MX-Based Keyboards: A Modern Powerhouse

MX-based keyboards are ubiquitous in the modern keyboard scene. Their versatility, wide switch selection, and customizable options make them a popular choice for gamers, typists, and keyboard enthusiasts alike. With a wide range of actuation forces and switch types, MX-based keyboards can cater to any typing preference.

Breakdown: Alps vs. MX Switches in a Nutshell

Feature	Alps Switches	MX Switches
Stem Shape	Rounded	Square
Actuation	Tactile "bump"	Cross-shaped actuation point
Pinout	Different from MX switches	Common across MX switch types
Compatibility	Requires adapters for MX-compatible PCBs	Direct compatibility with MX-compatible PCBs

Conclusion

So, there you have it, readers! Alps and MX switches are two distinct switch types with different physical characteristics and compatibility requirements. While adapters can sometimes be used to mount Alps switches on MX-compatible PCBs, it’s important to consider potential issues and performance limitations.

If you’re looking for a keyboard with the classic feel and sound of Alps switches, explore keyboards designed specifically for them. For a wide range of options and customizable features, MX-based keyboards reign supreme.

FAQ about Alps Switches and MX Switches

1. Do Alps switches use the same PCB as MX switches?

No. Alps switches have a different footprint and pin layout than MX switches.

2. Can I use an MX switch plate with Alps switches?

No. The mounting holes do not line up correctly. You will need an alps switch plate.

3. Can I use an Alps keycap on an MX switch?

Yes. Alps and MX keycaps have the same stem size, but they may not fit perfectly due to the different switch housings.

4. Can I use an MX keycap on an Alps switch?

No. The MX keycap stem is too large for the Alps switch housing.

5. Are Alps switches better than MX switches?

This is a subjective question with no objective answer. Both Alps and MX switches have their own unique advantages and disadvantages.

6. Are Alps switches more durable than MX switches?

Generally, yes. Alps switches have a solid slider design that is less prone to wear than the segmented slider design used in MX switches.

7. Are Alps switches more tactile than MX switches?

Yes. Alps switches typically provide a more pronounced tactile bump than MX switches.

8. Are Alps switches more expensive than MX switches?

Yes. Alps switches are less common than MX switches, so they can be more expensive to purchase.

9. Are Alps switches still being made?

Yes. Alps switches are still being produced by Alps Electric and are available from various retailers.

10. Where can I find Alps switches?

Alps switches can be purchased from various online retailers.
