Abstract
A switch actuator includes a base and a plunger mounted for movement on the base. An electrical contact is mounted for relative movement on the base to establish an electrical connection. An actuator assembly is mounted for movement on the base and is operatively associated with the plunger for effecting movement of the electrical contact to alter the state of the electrical connection. The actuator includes a pair of relatively movable members with a wedge member therebetween. The wedge member is effective to cause conjoint movement of the movable members and to allow relative overtravel movement between the members. The relationship between the electrical contact and the actuator assembly is adjustable to vary the movement differential of the switch actuator.
