This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. Generic micro switches follow a standard pin out with visible markings on the body of the switch. Here's each label markings:

  • (C1) – "common ground".
  • (NO2) – "normally open".
  • (NC3) – "normally closed".


  • (C 1) Common from micro switch to Ground on QTPy

  • (NO2) Normally open from micro switch to #0 on on QTPy
