A solid-state power controller in combination with a solid-state indication circuit is reminded for exhibiting OFF status using a depletion mode field effect transistor that permits an active signal to appear at its source and drain terminals when its gate, coupled to the power controller, is not energized. Such OFF indication circuitry is also combined with solid state ON indication circuitry using a device such as a bipolar transistor to exhibit an output when its base, coupled to the power controller, is supplied a signal.
