Abstract
A rotary switch assembly for use with a fuel burner valve having a user rotatable shaft. The switch has an annular sleeve which upon being received over the valve shaft is engaged to be rotated by the valve shaft. The rotor has a conductive contact ring frictionally engaging the rotor with inward projections on the ring frictionally engaging torque transmitting grooves formed on the rotor. The rotor is journalled on the switch base which has stationary contacts provided on opposite sides of the rotor. User rotation of the valve shaft causes the rotor to rotate and the wiper contacts complete a circuit between the stationary contacts.
Claims7
A rotary switch for use with a gas burner valve having a user rotated shaft comprising:
- (a) housing means including a base having a plurality of stationary contacts and connector terminals for external electrical connection thereto and a cover attached to the base;
- (b) an annular sleeve member formed of insulator material having a plurality of torque transmitting surfaces disposed about the periphery thereof in spaced relationship said annular sleeve having an end journalled on said base and an end journalled on said cover;
- (c) an annular contactor formed of electrically conductive material and having integrally formed thereon a plurality of first portions thereof defining wiper contacts for completing and breaking a circuit with said stationary contacts and a second portion thereof including certain cooperative surfaces engaging said torque transmitting surfaces for driving connection between said annular member and said contactor;
- and,
- (d) said annular sleeve member is adapted for being received over the valve shaft and engaged to be rotated thereby.
