This is a holder for common microswitches for X and Y at the same time. The switches I used are made by Marquardt but there should be plenty with the same dimensions from other manufacturers. As a trigger pin I used an M3 bolt on one Roller F and the long lever of the other bent to shape for the other. Attach the switches with 3 M3 bolts to the plate and use 2 M4x35mm instead of the regular 2 M4x 20 to lock the corner block. Pretty simple and stable.
