Abstract
In an appliance having a relatively low voltage control section controlling one or more AC power loads through switch devices such as triacs, the triacs are gated sequentially within each half cycle such that the peak load on the low voltage control circuitry caused by gating the plural triacs is equal to the load created by gating only a single triac. Distribution of the gating of plural triacs is accomplished through the use of a timing circuit or microprocessor, or RC timing circuits having differing time constants.
