I made a connector using a universal prototype board with a 1.27mm pitch. I checked quickly and confirmed it is making contact with the switch pins.

The back side of the connector, where it makes contact with the switch pins.
1.27mm pitch Universal prototype board

The following cross-sectional diagram shows how I attempted to connect the wires to the switch.
I wrapped the connector in polyimide tape to prevent it from short-circuiting with the switch case's feet.

  2. Wedge to secure the connector
  3. Cable
  4. Solder to attach wire to universal prototype board
