Reworked a good idea to make it more easily editable and useful. Uploaded version should provide 6mm of throw, parts can be scaled or edited to customize to your switch. I plan to use them on F-scale switches.

Mount the base, insert the arm, then the actuator. Last, install the Pin to lock it all together. The pin is a tight fit so expect to use some force. It should go and not require any glue. The downside is, no pulling it apart after that pin goes in!

I have added an arm with two holes, the pin goes in the arrow indicated placement of the pin.
