ABSTRACT:
A universal solenoid actuator for use with either a fail-safe or a fail-secure lock mechanism or a push-type or pull-type mechanism comprises a reversible coil assembly, at least one plunger and a module for receiving electricity from a power supply and delivering the electricity to the coil assembly. The coil assembly includes a housing which defines a bore extending through the coil assembly, at least one coil surrounding the bore and first and second fittings at opposed ends of the bore. The plunger is received within the bore and is actuated upon application of an electrical potential to the coil assembly. When used with a fail-safe lock, the first fitting is affixed to the lock. When used with a fail-secure lock, the coil assembly is reversed to affix the second fitting to the lock. Variations of the preferred embodiment of the inventive universal solenoid actuator are disclosed.
