Abstract
Exemplary embodiments are disclosed of a relay switch control configured for connection between a power source and a load. The control includes a processor having a clock upon which an operating frequency of the processor is based, and a sealed relay operable by the processor to electrically connect or disconnect the power source and the load. The relay switch control can start power to the load through the relay after a randomized time delay determined by the processor using a value of a counter of the processor. The counter is updated as a function of cycles of the clock.
