    High-Current Lighting Relays

    Switch lighting systems on and off—these relays can handle the high switching current on large overhead light systems. They control multiple circuits, so you can manage several lights across your facility with just one relay. For example, use them to switch overhead lights along with lighted signs in different parts of your warehouse. These relays come set for normally-open switching, but you can change them to normally-closed by turning the contacts around with a screwdriver.

    Electrically held relays can handle switching on and off frequently. However, because they need constant input voltage to keep the relay switched, they make a humming noise when switched on.

    Mechanically held relays are ideal for applications that don’t need to be switched very often, such as lights that stay on all day. Since they switch on and off with a quick burst of input voltage rather than needing constant power, they’re more energy efficient than electrically held relays.
