Title: Circuit transfer apparatus

Abstract: Circuit transfer apparatus is described for use in transferring from time-responsive control to temperature-responsive control, and vice-versa, in a microwave oven. The low cost, miniaturized apparatus is mounted to the wall of the oven's cooking cavity and is operated from within the cavity by insertion or withdrawal of the cable plug of the heat-sensitive food probe. The probe plug cooperates with insulative elements to activate spring-leaf sheet metal contacts mounted in the housing of the apparatus, to thereby effect the circuit transfer. The housing also serves as mechanical retention means for the probe plug.
