Abstract
A dimmer switch includes an air-gap switch for coupling to a power source, a power semiconductor switch electronically controlling power to a load connected in series with the air-gap switch, a dimmer module connected to the power semiconductor switch for coupling to the load to deliver an adjustable level of power to the load, and a dimmer actuator. The dimmer actuator is movable between an operational position and a disconnected position wherein the dimmer actuator is configured to act as a single control mechanism for selectively engaging either the dimmer module to adjust the level of power delivered to the load when in the operational position or the air-gap switch when in the disconnected position.
