20mm SPST Clear Glass Magnetic Reed Switch Round Button DPST Push Button The ESP8266 supports APSD forIt is a 20mm single polar single throw clear 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
