Switch assembly for use with equipment mounting apparatus backplane terminal pins. The assembly comprises an insulating housing member that is placed over a pair of adjacent terminal pins and secured to the backplane. An electrical shorting spring member positioned within the housing member engages both terminal pins to electrically short one terminal pin to another. An actuating member normally in engagement with the electrical shorting member is rotated by a connector inserted onto the backplane terminal pins to disengage the electrical shorting spring member from the pair of terminal pins.
