ABSTRACT:
A gear selector shaft of a vehicle transmission is held in respective positions by a yieldable latch element. The latch element actuates a switch when the gear selector shaft is in a predetermined position, such as in a reverse mode, so as to energize the back-up lights of the vehicle. The latch element is displaced by the gear selector pattern of the selector shaft in order to displace an actuator of the switch. A flexible steel membrane separates the actuator from the latch element. The latch element includes a first portion engageable with the gear selector shaft, and a second portion for displacing the switch actuator. The first and second portions are movable relative to one another once the switch actuator has deactivated the switch, so that the first portion can be further displaced without causing further displacement of the switch actuator and membrane.
