    Design-Your-Own Rocker Switches

    Choose from a variety of messages and colored lenses to combine a rocker with a base for a complete switch.
    Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed the bulb voltage.

    Use the screw terminals to hardwire these relays. The built-in enclosure protects contacts from dust and dirt. These relays accept voltage drops up to 50% of the rated voltage without switching. They’re often used with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

    Relay

    The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding. The screw terminals are recessed to prevent accidental contact with live connections. Mount them on 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces. These relays are built to IEC dimensional standards.

    10 Terminals

    Operate equipment that cycles on and off from your control cabinet. Often called definite-purpose contactors, these relays meet UL 508 for use with air conditioning and heating. Mount them directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They have recessed terminals that prevent fingers and other objects from touching live circuits. You can wire the control circuit on either side of the relay, which helps you use less wire.

    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
    Image of Attribute. Front orientation. Contains Annotated. Lighting Relays. High-Current Lighting Relays, Electrically Held, 4 Circuits Controlled.

    4 Circuits Controlled

    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.

    Controlled

    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.

    Relay Socket

    A single, maintained input voltage switches these relays and latches them in position, so they don't require a constant input voltage to stay switched. A second maintained voltage will release the latch.
    Relay Sockets—Relay sockets (sold separately) mount to 35 mm DIN rail (also known as DIN 3 rail) for fast installation.

    Circuit Board Safety Relays

    10 Terminals

    Reduce connection errors on circuit boards that control machine guards and other safety devices. Also known as force-guided contact relays, they have contact pairs that won’t close at the same time, even if contacts stick or weld shut. These relays take up less space on a board than those with electrical wiring because their solder pin terminals mount directly through circuit board holes. Use them to control high-power components, such as fans and heaters, from a low-power circuit.
    Surge Suppression Coverage—Relays with surge suppression coverage protect sensitive electronics from damage and malfunction by eliminating voltage spikes. Switching off a relay can generate surges of 300 to 500 volts, but a diode within these relays suppresses these surges. An LED indicator on these relays lights up when they’re on, so you know at a glance if they’re wired correctly.
