description The invention discloses a special device designed according to the magnetic field changing theory. Initiating different signals from magnetic sensitive elements with the magnetic field intensity alteration initiated by inserting , pulling, and lock rod breaking, so to tell the status of the lock. The electric components adopted in the invention are magnetic control tube, and magnetic sensitive hall switch integrated circuit, a magnetic circuit is formed when metal lock beam is fully inserted into the lock, the magnetic line of force passes through the magnet, magnetic medium ( iron, steel, copper, zinc alloy, aluminum alloy), lock beam and testing element forming a closed ring magnetic circuit, the testing element is switched on by strong exterior magnetic force as the signal power switch in control circuit. The testing elements is switched on and off together with the control circuit.
