High-Visibility Plastic 22 mm Emergency
Stop Panel-Mount Push-Button Switches
A base that lights up draws attention to emergency stops. When pushed, these switches immediately cut power. All meet IEC and ISO standards for emergency stop applications. Mount them in a standard panel cutout. Installation requires an additional 9 mm cutout for the illuminated ring.
Additional contact blocks (sold separately) can be added to control more circuits or replace the included contact blocks.

Plastic Enclosed Push-Button Switches
A protective plastic enclosure resists dents, chips, and cracks, so you can install these switches outside of panels. Mount them on a wall, for example, or tether them to a cord at your workstation. They actuate with a push for quick stops and starts. All are NEMA and IP rated to protect against corrosion, washdowns, and oil/coolant spraying. All have knockouts or integrated conduit connections to make it easy to attach conduit or add cord grips.
Flush buttons are easy to clean and difficult to damage because they mount flat.
Switches rated IP67 can also be submerged. Switches rated IP69K can also withstand high-pressure washdowns.

Hazardous Location 30 mm Panel-Mount Lever Switches
Made for areas where ignitable gas and vapor may be present, these switches have a housing that seals in anything that could spark flammable material. You'll know they're safe because they're NEC Class 1, Division 2, Groups A, B, C, and D certified for hazardous locations. They're also UL and C-UL listed and CSA certified. They require you to grip and twist a lever to turn them on or off, so they won’t accidentally actuate if you bump into them. Mount into a standard panel cutout.
Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.

Contact Blocks for Manual Switches
Make or break an electrical circuit. These contact blocks mount to manual switches and transmit an electrical signal when the switch actuator is engaged. You can stack multiple blocks, so a single switch can control several circuits. This is helpful in setups that require multiple systems to turn on or off at the same time. For example, the switch on a conveyor line could turn off the conveyor and turn on a diverter and alarm.

Low-Profile Limit Switches
Stack these slim switches together, or fit them into tight spaces. They're rated IP67 for protection from temporary submersion. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. They’re often used on conveyor systems and elevators.
Plunger actuators open or close circuits when objects push against them.
Roller-plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller moves parallel to the mounting direction, so it helps push the plunger even if the force isn’t straight on. The roller also reduces friction during actuation which prevents wear and tear over time.
Roller-lever actuators open or close circuits when material moves across the switch. The roller reduces friction during actuation which prevents wear and tear over time.
Switches with plastic or powder-coated zinc housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Sealed Low-Profile Limit Switches
A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. They're also rated IP67 for temporary submersion. With a slim design, you can stack them or fit them in tight spaces. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects. For instance, a box on a conveyor runs into the switch, stopping the conveyor.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a powder-coated zinc or plastic housing are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.
