Application
The switches are employed as magnet-sensitive contactless bistable limit switches.

Design and mode of operation
The magnetic switch consists of two dry-reed contacts embedded in cast resin and mounted in a corrosion-resistant brass casing. By the motion of a magnet, the contact and thus the circuit can be made or broken. When the contact is made, the magnetic field increases by the squared power as the air gap between the contact studs decreases and the contact closes abruptly. The contact switches almost instantaneously owing to the small distance between the contact studs and their low mass.

Magnetic switch bistable
The contact is magnetically locked in its respective position using two magnetic clamps. As the switching magnet is more powerful, the switch is set when the magnet moves over and is set back when the magnet returns.

Magnetic switch monostable
With this switch design, the switch remains activated for as long as the magnetic field influences it. The button returns to a neutral position when the magnet is removed.
