300V Metal Oxide Varistor (MOV) 14D471K temperature switch when a phototransistor passes throughThe Zinc Oxide Varistor (ZOV) is a nonlinear semiconductor voltage dependent resistor that is used in electrical circuits to limit the voltage. Electronic circuits and equipment without (MOV, ZOV, VDR) can be damaged or completely destroyed by transient overvoltages. They're mostly found in voltage sensitive electrical gadgets' protection circuits. A varistor effectively bypasses all transient surge voltages and prevents them from reaching the
