ABSTRACT:
Disclosed is a plug-in circuit arrangement for a ventilated range which permits a single, manual switch to control the level of heat output of the rear electrical heating unit in a surface cooking plug-in cartridge and also the level of heat output of a plug-in broil unit depending upon which of the two is inserted in the range, with the wiring of the receptacle and the broil unit combining, when the broil unit is plugged in, to operate the motor of the ventilating fan automatically whenever the broil unit is energized by the control switch, the same control switch, when actuated, energizing only the rear heating unit of the surface cooking cartridge, and not the ventilating fan, when the surface cooking cartridge is plugged into the range.
