Abstract: An electromagnetic lock monitoring system for monitoring the strength of a magnetic field in an electromechanical lock which is created when a steel armature plate is closed against an electromagnet. The system utilizes dual Hall Effect devices positioned in such a way that both ends of the electromagnet and both magnetic fields are monitored, and that the resulting monitoring effectively covers the complete contact surface between the electromagnet and the armature plate. Preferably, the Hall Effect devices are disposed in series at the point of maximum flux density within the center element of an E-shaped electromagnetic core, at opposite ends of the core. If the magnetic flux is below a preset limit, a relay also in series drops out, triggering an alarm which may be sonic, electronic, and/or visual, as is known in the prior art.

Abstract: A key alignment system for safety interlock switches uses alignment holes, and alignment pins to compensate for misalignment between a body assembly and a key assembly. The misalignment is often due to normal wear and tear or outright abuse of a gate or other movable member that should be safely interlocked. The key is fixed to a floating plate connected to a mounting plate by a suspension. The alignment pins and holes on or in a fixed alignment assembly and the floating plate can move the floating plate into a position such that the key enters the key hole. Some embodiments incorporate the fixed alignment assembly into the body assembly. The normal function of a keyed safety interlock wherein the key can be caught and held or released is preserved and enhanced by compensating for misalignment.
