Proximity switches and sensors use a reed switch and a permanent
magnet.
Each is encased in a plastic housing for protection and ease of
mounting.
A classic use is sensing the opening of a door in a securithy system.
A reed switch in the jamb and a permanent magnet in the door
complete a circuit when the door is closed.
Opening the door breaks the circuit.
Proximity switches can be achieved using a number of different
technologies depending on the application.
