Single-Pole Double-Throw (SPDT) Switch

DuoNode - Science & research. on Instagram: "This is about How SPDT relay actually works and tells us about how NO and NC pin works. SO, basically the switching between NO and NC is all because of the magnetic field that generates because supplied DC voltage across the relay. But still, because of rapid switching, and magnetic field. the reverse voltage is so high that can damage electronics. so usually designers' places diode in it. for protection of the circuit. #components #relay #electricale
