1L-MSM-117 – Surface Mount Magnetic Switch

Surface Mount Magnetic Switches work similar to relays, closing an electrical contact in the presence of a magnetic field. A nearby magnetic field from either an electromagnet or permanent magnet pulls one contact against the other, closing the switch. When the magnetic field is removed, the spring action in the stiff metal contacts opens the connection. Because the thin contacts have low mass, they can operate up to 10 times faster than conventional relays with similar ratings.
