A dimmer switch includes a first switch for coupling to a power source, a second switch, a dimmer module, and a main actuator movable between an operational position and a disconnected position. The main actuator includes a first switch actuator an d a second switch actuator. The first switch may be a normally-closed air-gap switch including a lever in contact with the first switch actuator. Movement of the main actuator between the operational position and the disconnected position is effective to open the switch. The main actuator is pivotally and slidably coupled to a frame. A coupling between the main actuator and the frame includes a pivot in a pivot holder; a partial cylindrical surface of the pivot is in contact with a surface of the pivot holder which includes a first portion having a partial cylindrical surface and a second portion having a'ramp surface.
