The 2×14mm Reed Switch is a compact, hermetically sealed magnetic switch that operates as a Normally Open (NO) contact. When exposed to a magnetic field, the internal ferromagnetic reeds close, allowing current to pass. Once the magnetic field is removed, the contacts return to their open state.

Ideal for use in security systems, door/window sensors, magnetic proximity detection, and automation applications, this reed switch provides reliable performance with no physical contact or mechanical wear, making it highly durable and long-lasting.
