An electrical type of lock wherein the mechanical movement is actuated in response to a solenoid system triggered by an electrical momentary signal. The locking bolt alternatively changes from a locking to unlocking position or vice versa in a snap action and is retained in its respective position. The bolt is modified by mechanical means in association with the solenoid.The locking arrangement and its actuation circuitry is particularly adaptable to a system wherein the initiating voltage is transmitted via communication lines i.e., telephone lines from a remotely located control station.
