Abstract
A solid state semiconductor power switch for controlling the application of AC power to a load wherein the power switch employs momentary ON/OFF switches for activating the power switch, and wherein additional circuit means is provided to preserve the ON/OFF condition or state of the power switch during a power-down situation such that upon restoration of the AC power the power switch can be caused to assume the same ON or OFF state it was in just prior to the power-down situation.
