Abstract

A switching device is provided having an air-gap switch for an electrical load. The switching device can include a switch keycap configured for controlling the switching of the electrical load. A faceplate can be configured to surround the switch keycap. In addition, an air-gap actuator can be contained substantially within the switch keycap. The air-gap actuator can be pulled from the switch keycap to short out an electrical connection to the electrical load.
