A semiconductor switch is a non-physical contact switch. if use a multimeter diode or resistor to test ,it always show a high-impedance state, (multimeter light red).According to the conventional detection methods of solid state relays: a load is required to test the switching state. Using an incandescent as a dummy load is an obvious way to test continuity.Theory : Solid State Relayis_customized : YesContact Load : Low PowerOrigin : Mainland ChinaFeature : Sealed
