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.

Abstract: A multiple contact filter connector capable of accommodating high RF currents and a method of manufacturing the same are disclosed. The connector includes an outer metallic shell, a dielectric body within the shell and at least one network filter contact assembly. The inner body has at least one through channel and a transverse cavity which communicates with the shell and the channel. The network filter contact assembly has a ground electrode and a pin electrode and is disposed within the portion of the channel bridging the cavity. Conductive curable filler material is charged into the cavity around and in contact with the ground electrode to efficiently and inexpensively establish a ground plate for the connector. A retention means disposed within the channel and a locking means carried by the contact cooperate to provide axial strain relief, thereby protecting the bond between the conductive filler material and the ground electrode.
