Relays

Relays — New & Used

Relays are essential switching devices used to control electrical circuits by opening and closing contacts in response to input signals. Available in electromechanical, solid-state, and time-delay configurations, relays enable isolation, automation, and load control across countless applications — from industrial machinery to control panels and building systems.
