1. A control circuit for an electrical load connected to a power circuit, the control circuit comprising:
- a switch path in signal communication with the load and arranged to turn the load ON and OFF, the switch path having a switch and a series connected voltage generator; and
a controller in signal communication with the switch;
wherein the controller is responsive to a voltage at the power circuit under a switch OFF condition and responsive to a voltage at the voltage generator under a switch ON condition.

Abstract
A control circuit for an electrical load connected to a power circuit includes a switch path having a switch and a series connected voltage generator, and a controller in signal communication with the switch. The switch path is in signal communication with the load and arranged to turn the load ON and OFF. The controller is responsive to a voltage at the power circuit under a switch OFF condition and responsive to a voltage at the voltage generator under a switch ON condition.

11. A method of powering a control circuit and controlling an electrical load, the control circuit having a switch path for turning the load ON and OFF, the electrical load being connected to a power circuit, the method comprising:
-
in response to the load being in an OFF state and the switch path being open, receiving a first voltage from the power circuit;
in response to the load being in an ON state and the switch path being closed, receiving a second voltage from across the switch path;
wherein the first voltage is an AC voltage, the second voltage is an equivalent DC voltage, and the second voltage has a value less than the AC-RMS value of the first voltage. - View Dependent Claims (12, 13, 14, 15, 16)
