Bistable Magnetic Switches

About Bistable Magnetic Switches

Bistable Magnetic Switches are advanced contact devices that operate using a permanent magnetic field to change and hold their contact state (open or closed) until acted upon by an opposing magnetic field. Unlike traditional switches that require continuous power to maintain a state, bistable switches remain latched in position, offering excellent energy efficiency and operational reliability. Widely used in elevator door systems, access control, security devices, industrial automation, and smart home systems, these switches provide precise position detection, long service life, and resistance to environmental factors like dust, moisture, and vibration. Available in various configurations including normally open (NO), normally closed (NC), and changeover contacts, bistable magnetic switches are compact, maintenance-free, and suitable for both surface and concealed mounting.
