Abstract
A portion of a solenoid coil melts after a predetermined time period has elapsed to interrupt the flow of current through the coil. The portion which melts can include a reduced cross sectional area which increases the resistance of the portion of the wire. Alternately, a portion of the coil wire can be formed from a material having a higher resistivity than the remainder of the wire.
