  • Switch Type *

    The switch type affects the length of supplied standoffs and thickness of acrylic plates

  • Diode Type *

    Through-hole diodes might be a bit easier to work with, but if you have a decent pair of tweezers and a reasonable iron, SMD diodes are actually quicker/simpler to solder - no faffing about with legs :)

  • Switch Plate Colour *

    For Kailh Choc switches, the switch plate is 2 mm thick with limited colour options

  • Case Colour *

    For Kailh Choc Switches, this only applies to the bottom plate
