Handbrake and Shifter Combo for Sim Racing (Updated)

Initial design and test for a combo handbrake and shifters using 90mm RC shocks for parts. 
 

Handbrake is On/Off version at this point due as its easier to wire with the board selected. 

V2 design uses a bearing and standoff to compress a spring in the handle while the bearing runs along a track.
