More Information
Summary:A relay assembly that includes a relay, a bypass switch and a controller. The relay includes an electromechanical switch with an open state and a closed state. The bypass switch is operatively coupled in parallel with the electromechanical switch of the relay, and also has an open state and a closed state. The controller is operatively coupled to the relay and the bypass switch, and is configured to switch the bypass switch from the open state to the closed state, then switch the relay between the open state and closed state, and then switch the bypass switch back to the open state. In some cases, the bypass switch includes a TRIAC. The controller may be configured to maintain the bypass switch in the closed state for less than 100 milliseconds before switching back to the open state.
