HIGH MECHANICAL ADVANTAGE ELECTRICAL RELEASE STRIKE A release strike assembly, comprises: a) case having a side opening, b) a strike bolt pivotally supported by the case to swing between extended and retracted positions relative to the case, c) a first spring yieldably urging the bolt toward extended position, d) a first latch element pivotally supported for swinging movement within the case between first and second positions, the first element in its first position blocking the bolt against swinging toward its retracted position and in its second position allowing the bolt to swing toward its extended position, and e) a second latch element pivotally supported for swinging movement within the case between primary and secondary positions, the second latch coupled to the first latch element to pivot with the first latch element, f) and an actuator to effect pivoting of one of the latch elements. |
