14mm Gold Plated Normally Open Magnetic Reed Switch for Proximity Detection, Arduino DIY Electronics Sensor

The 14mm Gold Plated Normally Open Magnetic Reed Switch is a compact, highly sensitive switching component designed for magnetic field-based control applications. It operates as a sealed glass tube switch that closes or opens when exposed to a magnetic field, making it ideal for contactless switching systems.

With gold-plated contacts, this reed switch ensures excellent conductivity, low contact resistance, and long operational life. Its normally open configuration keeps the circuit OFF until a magnet is nearby, enabling precise control in automation and sensing applications.

This component is widely used in security systems, door sensors, robotics, automation projects, and Arduino-based electronics. Its small 2x14mm size allows easy integration into compact designs and embedded systems.
