ABSTRACT:
The disclosure relates to an electric cigar lighter for use, for example in vehicles, having an improved circuit breaker which includes at least two thermostatic contacts mounted on a bottom of a tubular holder for receiving an igniting unit, an end cap secured to the outer face of the tubular holder, a movable contact unit which is movable in the end cap and a spring mounted in the end cap so as to rearwardly urge the movable contact unit. The thermostatic contacts are adapted to contact a bimetallic latch mounted in the tubular holder, and to rearwardly extend into the end cap. The movable contact unit includes a contact member in a form of a cap which, at a front end portion of a cylindrical wall thereof, a rib which is adapted to be engageable with ribs formed at the rear ends of the thermostatic contacts. During a normal operating condition, the ribs of the thermostatic contacts engage the rib of the contact member to retain the removable contact unit at the closed-circuit position, while, when the heating element is overheated and the thermostatic contacts are transformed due to the heat from the heating element, the spring causes the thermostatic contacts to disengage from the contact member to rearwardly move the movable contact unit toward an open-circuit position.
