ABSTRACT:
A switching and heat control mechanism for induction heating cooking apparatus having a plurality of induction heating work coils comprises a single control shaft provided with a plurality of contact operating members. A plurality of switch contact units operable by the corresponding contact operating members provide different combinations of open and closed circuit conditions for various points of the apparatus in sequence as the control shaft is rotated. An elevating mechanism, carrying an associated work coil, moves the coil up and down in response to the angle of rotation of the control shaft to form a variable, power level controlling gap between the coil and a load placed on a nonmagnetic cook top.
