Abstract
An electric lighter for a vehicle includes a lighter plug insertable into a dashboard socket having a bimetallic yoke engageable with an end of the plug for energizing the glow coil of the plug. An overload protective device is disposed in the socket and comprises a bimetallic snap-action disc disposed immediately below the yoke and connected electrically in series therewith. The snap-action disc has a first shape in its operating condition where it completes the circuit to the glow coil through the yoke and assumes a second shape when it snaps to its switch-off position in response to an overload condition to open the circuit to the glow coil. The snap-action disc remains in its switch-off position after cooling and must be manually reset to its operating position to restore operability of the lighter by the engagement of a manually actuated reset device associated with the socket with a peripheral portion of the snap-action disc. The resetting can be performed by having the socket axially movable against the bias of a spring in an illumination sleeve, so that resetting takes place when the lighter plug is inserted into the socket.
