Dormakaba Program Switch

Dormakaba Program Switch, like gate position switches, use magnets and a magnetic sensitive switch to operate. The switch is installed in the door frame and a magnet is positioned on the top of the door. The switch lies in a balanced-bias magnetic field of multiple magnets when the door is closed including the magnet on the door and others within the switch. When the door opens, the switch is closed because the unstable magnetic field is broken. In an attempt to bypass the magnet on the door, another magnet can be placed near the switch to activate it.
