Abstract
A conversion apparatus has a magnetic latching solenoid equipped with a special plunger shaft and piston mechanism which can move independently of the plunger, allowing mechanical locks to operate with momentary battery power. The plunger shaft is bored to accept the piston which consists of an inner shaft and a locking pin. The locking pin and inner shaft are secured to the plunger shaft with a light spring. With this mechanism, the operation of locking and unlocking is complete, regardless of readiness of the locking device, since the locking pin will move to the intended position of locking/unlocking after momentary prevention such as premature twisting of the lock knob.
