Abstract: A thermally actuatable electrical switch construction having a deformable contact member normally disposed in electrical contact with a stationary contact member while a temperature sensitive member of the construction is in a solid condition and being deformed out of contact with the stationary contact member by deforming means of the construction when the temperature sensitive member is rendered non-solid by sensing a temperature above a predetermined temperature, the deformable contact member being deformed in a direction toward the temperature sensitive member by the deforming means when the temperature sensitive member is rendered non-solid and being carried by a lead that projects into the switch construction whereby the lead and the deformable contact member define a subassembly that is adapted to be initially inserted into the construction to be secured thereto.

Abstract: One half of a main motor winding and a shunting lead are connected between one side of a power source and two of the terminals of a three terminal plug-in receptacle; the other half of the main winding and a second shunting lead are connected at one end to the other side of the power source and each has a plug-in terminal connected to its other end for selectively connecting the two winding halves in parallel or in series across the power source.
