Abstract
A known switch is mounted on a base of a switch actuator assembly. When the switch is to be actuated, an input shaft and switch actuator member are rotated together relative to the base. A helical return spring urges the input shaft back toward the initial position. When the input shaft and switch actuator member have been rotated together to an actuated position, the switch is actuated and the switch actuator member engages a stop surface. During continued rotation of the input shaft from the actuated position to an overtravel position, a pin connected with the input shaft moves away from one end of a slot in the switch actuator member. A helical overtravel spring is deflected along with the return spring. Deflection of the overtravel spring urges the switch actuator member and input shaft back toward their initial position relative to each other.
