Pressure plate modification for the Vex Bumper Switch. This modification was tested with hard stops to prevent the plate from applying side loads on the switch which could cause it to break off. To mount this mod securely to the bump switch, I recommend using super glue and letting it cure for 24 hours to mount this mod securely to the bump switch. To access the top portion of the bump switch, you must remove the four bolts in the back of the housing to expose the two bolts that secure the bumper switch to the top portion of the sensor.
