ABSTRACT:
A rotary switch is disclosed which has a ferrule, rotor and stator assembly housed within a plastic cylindrically shaped housing. The ends of the housing are uniquely folded to hold the ferrule and stator in end positions within the housing on edges located on the interior wall the housing. The rotor has a shaft which is rotatably mounted in the ferrule for relative movement over the stator. Stationary contacts are provided on the stator, while moveable ball contacts carried by the rotor seat on the stator for displacement relative to the stationary contacts upon turning of the rotor via the shaft. A detent mechanism cooperates with the interior wall of the housing to establish detent positions corresponding with predetermined electrical coupling of the stator contacts by the ball contacts.
This housing arrangement provides a relatively simple and inexpensive rotary switch of relatively small sized which has a high switch capacity.
