   Magnetic switch. Magnetic switch is an electrical switch that makes or breaks contact in the presence of a magnetic field.Applications include situations where it is not desirable or possible for moving elements to make direct contact with the switch, such as in explosive environments, submerged in liquids, and where repetitive contact with a mechanical switch would result in undesired wear.

   en.wikipedia.org/wiki/Electromagnetic_lock

   Operation. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. The magnetic lock relies upon some of the basic concepts of electromagnetism.
