ABSTRACT:
A control switch having an air gap safety lever, a novel slide arrangement, and an illuminated on-off control switch. The air gap safety lever is mounted on the control switch in such a manner that no power may flow through the circuits until the unit has been installed and the front cover plate mounted. The slide arrangement employs a thin clip which provides an aesthetically appealing slide control, the clip having special dimples which allow nearly frictionless movement. The illuminated on-off control switch utilizes a light piping which conveys light from an LED to the on-off button, the light piping doubling as a mechanical link between the on-off button and a momentary contact switch mounted inside the control switch. Also, a novel frame is disclosed which secures all mechanical and electrical components of the switch together without the necessity of attaching the back box, which simplifies test and repair before shipment of the unit from the factory.
