ABSTRACT:
An integral infinite switch is provided for controlling a first coil and a second coil of a radiant heating element. The integral infinite switch includes a first switch assembly for opening and closing an electrical path between a first AC electrical line L1 and a first end of the first coil. The first AC electrical line L1 is directly connected to a first end of the second coil. The integral infinite switch includes a second switch assembly for opening and closing an electrical path between a second AC electrical line L2 and a second opposite end of both the first coil and the second coil. A spindle is rotatable between an OFF position, a first range of ON positions for the second coil and a second range of ON positions for the first coil and the second coil. A cam member is mounted on the spindle for rotation with the spindle. The cam member includes a first cam surface adapted for operative engagement with the first switch assembly and a second cam surface adapted for operative engagement with the second switch assembly.
