Abstract
The present invention is directed to an electronic switch device that includes a front cover assembly having a user interface, a back body assembly, and a plurality of terminals configured to be coupled to an AC power source and the load. A circuit assembly is coupled to the plurality of terminals. The circuit assembly includes a relay switch having a commutator and a set of contacts. The relay switch is characterized by a predetermined commutator period, the predetermined commutator period being substantially the commutator travel time between the set of contacts during a relay switch actuation. The circuit assembly further includes an actuation circuit configured to provide a constant current actuation signal that energizes the relay switch in response to an input stimulus via the user interface such that an end of the predetermined commutator period substantially coincides with a predetermined point in an AC power cycle.
