Thanks to their ability to handle higher current than switches with contact blocks, these switches are often found in applications from large motors to warehouse lighting systems. The cam pushes contacts more tightly together than contact blocks, allowing more electricity to flow through. However, they aren’t made to be rewired like switches with contact blocks are. These switches require you to grip and twist a lever to turn circuits on or off, so they won’t accidentally actuate if you bump into them. Mount them in a standard panel cutout diameter.

Choose a switch based on the complexity of your application. On/off switches have two positions. Changeover switches have three positions. They work well if you need to toggle between a primary power source and a backup generator. Selector switches have up to six positions. They give you the most control, allowing you to turn on or off multiple devices or different parts of your machine.

Legend plates (sold separately) give you a way to change your switch’s message.

Install these switches in a panel cutout. Small enough to fit in tight spaces, they handle comparable electrical loads to standard sized switches. They cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. All have a lockout so you can secure them in the off position with a padlock (not included). They’re rated IP65 for protection from washdowns.

Small yet mighty, these switches are about as tall and wide as an index card yet durable enough to mount directly to a wall. Their polycarbonate housing protects the switch and resists denting, chipping, and cracking. Rated IP65, the housing also seals out water even in frequently washed down areas. Don’t be fooled by their size—these switches can handle electrical loads comparable to a standard sized switch.

Using a low-current signal, these relays are often used to control small motors and heaters. These relays attach to quick-disconnect terminals.

Relay-socket mount relays plug into a socket (sold separately).

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. Relay sockets with screw terminals can also mount to a flat surface.

Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.

Relays with circular-pin terminals plug into relay sockets (sold separately) for easy installation. They are hermetically sealed.

Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.
