Abstract:
An electrical switch device includes a housing, faceplate, and a light pipe assembly that includes a light transmissive channel, a position stop, and a cam. The device also includes an air gap switch having a movable contact assembly and a stationary contact assembly. The movable contact assembly includes a cam follower that engages the cam of the light pipe assembly. The light pipe assembly is configured to pulled outward from the outer surface of the faceplate. Movement of the light pipe assembly cause the cam follower of the movable contact assembly to move along the cam and separate the movable contact from the stationary contact, shorting the circuit. Pushing the light pipe assembly in a direction back into the faceplate causes the cam follower to move in the opposite direction along the cam and allows the movable contact to engage the stationary contact and close the circuit.
