ABSTRACT:
A heat-sensitive variable-resistance insert device for use with a light bulb and socket, including: a heat-sensitive variable-resistance wafer for interconnecting the central contact of the socket with the central contact of the light bulb. An annular insulation member surrounds the edge of the wafer and electrically insulates it from the wall of the socket. A resilient contact is mounted on at least one side of the wafer for resiliently engaging the associated central contact and accommodating for variations in the distance between the central contacts.
