  • Patent number: 4565994
    Abstract: A device for detecting the removal of a cylinder lock used on cars, trunks, etc. when an unjust force is applied to the cylinder lock. The device also detects the locked and unlocked conditions of the cylinder lock. Magnets and magnetic sensor switches are used. A magnetic shield plate shields the flow of magnetic flux between the magnet and the magnetic sensor switch. When an unjust force is applied to the cylinder lock to take off the cylinder lock, the magnetic shield plate will be removed from between the magnet and the magnetic sensor switch, causing the magnet to energize the magnetic sensor switch, thereby detecting the removal of the cylinder lock.In addition, when the cylinder lock is turned by a key, another magnet connected to a rotor of fixed on the cylinder lock approaches either of a pair of magnetic sensor switches, whereby the locked and unlocked conditions of the cylinder lock are detected.
