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 lamp as a dummy load is an obvious way to test continuity.
