For some DCS planes you can achieve button press on toggle switch OFF position editing LUA files.
In other games using SVMapper or HIDMacros can map functions on press (ON) and released (OFF) of swtiches.

Depends on use of this " three-way on/off/on toggle switch" you can wire a always on connection for middle pins of DPDT switch.

Anyway Desktop Aviator have some boards that do this in hardware (send button press in ON and OFF).
