Description

Recessed Mount Magnetic Switches are high-speed switching devices that function similarly to relays, using a magnetic field to close an internal electrical contact. When a nearby magnet—either permanent or electromagnet—is present, the contact closes. Once the magnetic field is removed, the spring tension in the metal contacts instantly reopens the circuit.

Designed with low-mass internal contacts, these switches deliver switching speeds up to 10 times faster than traditional mechanical relays. The included ¾″ adaptor holder makes installation both easy and secure, especially in recessed or hard-to-reach areas.
