Abstract

A regulating switch circuit for conditioning operation of a first load upon operation of a second load wherein the first load and the second load consume electrical energy from a power source includes a detecting means for detecting the operation of the second load and a sensing means for sensing an amount a parameter of the electrical energy supplied to at least one of the first and second loads exceeds a predetermined level. A load control device couples at least one of the first and second loads to the power source wherein the load control device has a control terminal. A control circuit is coupled to the control terminal of the load control device and is responsive to the sensing means and the detecting means to variably adjust the electrical energy supplied by the power source to at least one of the first and second loads to limit the parameter of the electrical energy to the predetermined level.
