Abstract
A solid state switch (SS) for controlling a load (1) supplied from either an alternating current (AC) or a direct current (DC) power supply line (L1, L2) having a pair of solid state devices (FET1, FET2) for controlling energization of the load and a common control circuit (CC) therefore which includes a diode isolated, capacitive-reactively coupled, line-derived power supply circuit (PSC) for the common control circuit and an opto-isolated logic signal input circuit (ISO) such power supply circuit effectively eliminating the need for transformers or the line.
