Abstract
An electronic combination lock of the self-powered type, wherein the electrical energy for operation of the lock is developed within the lock itself, has a solenoid which magnetically seals in the activated position, thus preserving the 'open' condition of the lock until such time as the operator may withdraw the bolt. Significantly, there is no requirement for continued electrical power to hold the solenoid and the latching mechanism in a condition for lock opening.
