Abstract
An electric cigar lighter, such as used in a motor vehicle, has a bimetallic switch in the form of a snap disk positioned within a socket. When using commercial appliance plugs with such a snap disk, the diameter of the socket does not need to be enlarged compared to conventional sockets. Contact bounce and contact interruptions are prevented. These advantages are achieved by placing the contact disk and a contact part on an adjustment ring inserted with a sliding fit into a tubular member located within the socket. A control knob for the lighter fits into a plug sleeve within the socket. A spring spider on the control knob locks onto an annular bulge on the plug sleeve provides a pressure point for quickly switching the heating element to the on-position.
