Abstract: A positive temperature coefficient of resistance resistor/overload (PTCR/OL) resistor assembly that can be quickly and easily electrically connected and disconnected from equipment without the need for special tools or equipment. In some arrangements of the present invention, a locking tab on the electrical connector can be secured against an angle on the PTCR/OL to prevent the electrical connection from being broken during shipping or operation equipment movement or vibration. When it is necessary to electrically disconnect the PTCR/OL from the equipment, the locking tab can be disengaged from the angle on the PTCR/OL by bending the tab until it releases from against the angle, and the electrical plug can then be disconnected from the PTCR/OL. The improved assembly provides increased isolation of incoming electrical wires with less material than previous devices.

Abstract: A condition-responsive electric switch mechanism for use in controlling a compressor of a refrigeration appliance. The switch mechanism includes first, second and third terminals, an actuator movable as a function of a detected condition and a bistable spring switch element electrically connected to the first terminal. The spring switch element includes a movable contact and is adapted for snap-acting movement between an open and a closed position. In the open position, the movable contact of the spring switch element is spaced apart from a fixed contact mounted on the second terminal. In the closed position, the movable contact engages the fixed contact to electrically connect the first and second terminals. The spring switch element also includes a toggle blade operable by engagement with the actuator for motion through a first switch point. At the first switch point, the spring switch element snaps between the open and closed positions.
