ABSTRACT:
A cigar or cigarette lighter, particularly for mounting on the instrument panel of a motor vehicle, is effective to light the cigar or cigarette when a control knob is moved within a cylindrical casing, the control knob being connected to a metal rod which is provided at its inner end with a movable contact engageable with a fixed contact to energize an electrical heating resistance element within a hot plate, the cigar or cigarette being lighted when placed against the heating plate on energizing the heating resistance element to incandescence. A bimetal safety contact is insulatingly fitted on a threaded stem below the hot plate, the threaded stem also carrying the hot plate at its inner end and feeds electric power thereto. The bimetal safety contact expands under prolonged heat action to establish a contact to the cylindrical casing which is grounded thereby producing a short circuit which blows a fuse in the instrument panel to interrupt the feed of electrical power to the lighter. A continuously energized LED indicator enables ready determination by the user of the location of the cigar or cigarette lighter.
