ABSTRACT:
A rotary switch having a terminal base molded on a lead frame which includes internal contacts and external terminals, along with the connecting straps between them, all formed of a single metal part. Portions of the metal of the lead frame are selectively removed in order to create a variety of switch configurations. Different switch actuating rotors are provided which further allow creation of different switch modes (single throw, double throw, etc.). The rotor is also provided with detents in order to allow for retention and indexing of the switch positions. A ramp may be selectively installed into the rotor to eliminate unwanted detent positions without requiring a different rotor. One or more "floating" movable contact elements complete the circuits when the rotor allows a respective spring to force a floating movable element into contact with both of a corresponding pair of stationary contacts of the terminal base. A separately usable illuminated indicator module is mounted on a bushing surrounding the switch rotor and the knob of the switch transmits light passing from the indicator module to the front of the knob where it can be viewed. The module includes a light distributor which directs the light from a single lamp to several positions corresponding to the switch positions.
