Introduction

Use this guide to replace a faulty switch in your EPOMAKER EK21 VIA numeric keypad.

The switch is the most crucial component of any keypad, as it allows the device to accept key presses. If a key becomes unresponsive or isn't functioning as it should be, then the culprit may just be the switch and not the entire device itself.

Before using this guide, inspect the device for chunks of debris that may be stuck in between the keys. A buildup of dirt and debris may cause the key be physically unable to be depressed. A small buildup of debris can be easily cleaned with a can of compressed air or a small ESD-safe brush.

Step 5

Confirm that the replacement switch you are using is a two-pin switch.

Step 6

Align the replacement switch so that the pin on the left is positioned lower than the one on the right.
The switch can only be inserted in one orientation.
Forcing the switch into the board in the wrong orientation may result in damage to the switch. Be sure that the pins are clean and straight, as you may risk damage to the switch.
Push the switch down fully so that it is flush with the board.
You may use your finger to give it a little push so it sits securely in the board. Be gentle as the pins are prone to bending.

Push down on the keycap so that it fits on the switch without falling off.
You may use your finger to press the key down all the way to ensure it feels the same as the other keys.
