ABSTRACT:
Disclosed is an electrical connection system for a microwave oven including a chamber defining a housing, a source for transmitting microwave energy into the chamber, a turntable rotatably mounted within the chamber and defining stations for receiving articles to be heated and a drive mechanism for producing rotation of the turntable. A control circuit controls energization of the source in response to signal outputs from temperature responsive sensors positioned in the heating stations. The rotary coupling includes a stationary portion mounted on the housing and having stationary contacts connected to the control circuit and a rotary portion mounted on the turntable and having rotary contacts connected to the sensors and slidably engaging the stationary contacts during rotational movement of the turntable.
