Leone 14mm SPST Green Magnetic Reed Switch 3.9E 4 Inch TFT SPI ModuleIt is a 14mm single polar single throw green glass magnetic reed switch . It's a passive electrical switching component that regulates the flow of electricity in a circuit. It consists of a glass envelope, containing two ferrous elastic reeds and an insert gas or a vacuum. Both reeds are normally apart but once the magnetic field approaches the sensor, they will come together, completing the circuit. Electromagnetic relays, weighing devices, level
