Short Description

Hot-plug supported, upgrade the microswitches for your G403 or G703 left-right button, and easily change them after the old microswitches wear out.


  • This item has no microswitches on the PCB board by default. You can select microswitches with an extra $2 in the Installed Microswitch dropdown.
  • Some microswitches have larger pins (like Cherry DG4), you might need to sand the pins a bit.

Hot-plug supported, you can customize the microswitches as you like on the left and right buttons, and easily change them after the old micro switches wear out or malfunction.


Desoldering and soldering are required to remove the old PCB boards and connect the hot swap PCB boards with the cables.
