Magnetic Reed Switch 14mm Glass Tube

The Magnetic Reed Switch 14mm Glass Tube is a compact, high-sensitivity magnetic sensor used to detect proximity, movement, and position. It consists of two metal contacts sealed inside a durable glass tube. When a magnetic field approaches the switch, the contacts close and complete the circuit.

This makes it ideal for home security systems, automatic door detection, IoT devices, and Arduino-based magnetic sensing projects.
