Impact-Resistant Pendant Switches
A durable rubber housing covers the buttons and protects these switches from impact. Use them with mobile machinery such as cranes, hoists, and trolleys. All can be wired to prevent two buttons from operating simultaneously.

Snap-Acting Switches
Open and close circuits quickly to minimize arcing and prevent contacts from sticking. These switches are often used as door-open indicators on appliances and enclosures or as an internal component in limit, pressure, and temperature switches.
Plastic covers (sold separately) are compatible with switches with screw terminals. They fit over the bottom of the switch to prevent contact with live terminals.

Manual Motor Starters
Provide on/off control for a motor and protect it from overloads. These starters shut off the motor if current exceeds the full-load current rating. All have an adjustable overload relay that allows you to set the exact overload current you need.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
Starters with auxiliary contacts can send a signal or connect to another device, such as an alarm or indicating light.
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.

UL listed, C-UL listed, and CE marked, these switches meet American, Canadian, and European safety standards.
Use optional sealing gaskets in washdown environments; they create an IP65 rated seal around the actuator.
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.
Use additional power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

DIN-Rail Mount Solid State Relays
Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.
Relays with an integrated fan are best for applications that generate more heat. The fan automatically turns on to provide additional cooling. When the temperature exceeds 176° F, an alarm sends a signal to an external device, such as a controller or indicating light.

DIN-Rail Mount Touch-Safe Screw Terminal Relays
Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.
Relays that control 3 and 4 circuits are built to IEC dimensional standards and are often called IEC contactors.
Auxiliary contacts (sold separately) allow you to add a signaling device or control another relay. You can add one auxiliary contact to all of these relays. For relays with 12 terminals, you can add two side-mount auxiliary contacts.

Touch-Safe DIN-Rail Mount Infrequent-Cycle Relays
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. They mount directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. These relays have recessed terminals that prevent fingers and other objects from touching live circuits.
Auxiliary contacts (sold separately) allow you to add a signaling device or control another relay.

Infrequent-Cycle Relays
For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Connections are accessible from the front, so you can mount relays side-by-side. Also known as definite-purpose contactors.
Enclosures (sold separately) are NEMA 1 rated to protect contacts from corrosion.
Also Available: Auxiliary contacts for 3.8"-7.2" Ht. relays. They allow you to add a signaling device or control another relay. Please select 6564K99, then select the McMaster-Carr part number of your relay and whether you want to switch one circuit on (1 Normally Open) or off (1 Normally Closed).

Screw Terminal Relays
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.
