Abstract: The present invention related to a universal semiconductor switch. In one embodiment, the switch includes a switching arrangement having an input power connection configured as input for a solid state switching device, the solid state switching device operationally coupled to a current limiting arrangement and an output circuit; the output circuit including a filter circuit. At least one trigger circuit including a power source and an on-and-off circuit, said trigger circuit operably coupled to the switching arrangement input power source and the solid state switching device. An on-command noise immunity circuit and an off-command noise immunity circuit are operationally coupled to the trigger circuit to suppress the noise from any external source, the switch will trigger only if the detected voltage is beyond the threshold voltage and for a predetermined duration.
