ABSTRACT:
A plunger actuated switch, suitable for automotive brake light applications where the plunger is held depressed in de-actuated condition. Upon installation, the switch housing is moved on an adjustable mounting to cause the plunger to contact a user moveable operating member such as a brake pedal arm. The switch mounting is adjusted to cause the plunger to depress and move the internal switch actuator to its limit of travel; and, the switch is further adjusted to cause the plunger to ratchet over an adjustment member carried by the actuator to provide an adjusted position of the switch. The adjustment member has spring fingers which are bowed during the adjustment; and, upon subsequent release of the user moved operating member, i.e., a brake pedal arm, the plunger is spring biased away from the fingers which snap inwardly to thereafter permit relative motion of the plunger with respect to the actuator when the actuator is at its travel limit to thereby provide overtravel absorption.
