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.
Mushroom buttons stick out and are often used to stop equipment because they are easy to push.
Switches rated NEMA 3S will also work in cold temperatures and when covered in ice.

Plastic Emergency Stop Enclosed Push-Button Switches
Made of yellow polycarbonate plastic, these enclosed switches are easy to see and resist dents, chips, and cracks. They are more corrosion resistant than aluminum enclosed switches and withstand washdowns and oil/coolant spraying. Mount them to a wall or attach a cord grip to position them at your workstation. They have positive force contacts that will open a circuit when actuated, even if a spring fails or the contacts stick. A single push will immediately cut power.
The switches can be reset by manually pulling, turning or unlocking them by key. Switches with a guard prevent accidental actuation. To stop the switches from being reset or turned on during machine repairs, lock the guard with a padlock.

Plastic 30 mm Panel-Mount Lever Switches
Prevent accidental actuation from bumps or jostles—these switches require you grip and twist a lever to turn them on or off. Install them into standard panel cutout diameters. They include enough contact blocks to control the number of circuits listed. These switches are rated NEMA 4X, 13, and IP65 for protection from corrosion, washdowns, and oil/coolant spraying.
Three-position switches are off in the center position.
Illuminated switches are easy to see in dim and dark areas. To help users identify switches without having to read labels, install differently colored switches for different tasks.
Additional contact blocks (sold separately) can be added to control more circuits or replace the included contact block.

Plastic Enclosed Lever Switches
The enclosure not only protects these switches, but also adds options for how you install them. Secure them to a wall or use the knockout to attach a cord grip and cord, so you can move them around your workstation. Made of polycarbonate plastic, the enclosure resists denting, chipping, and cracking. It’s also NEMA rated to withstand corrosion, washdowns, and spraying oil or coolant. Since you have to twist the lever to actuate these switches, they won’t accidentally flip if someone bumps into them. Choose switches based on their actuator color for an easy way to tell them apart.
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.

Joystick Switches
Intuitively steer and position cranes, robot arms, and other machinery that moves in multiple directions—your equipment will follow the movements you make with these joysticks. They control multiple circuits as you move them in different directions and patterns. Assemble a complete switch with an actuator and at least one contact block (sold separately). All actuators include a mounting clip that can fit up to two contact blocks. They’re NEMA and IP rated for protection from dust, washdowns, and oil/coolant spraying.
Two-position actuators require one to four contact blocks. Four-position actuators require two to four contact blocks. They are off in the center position.
Lockable actuators have a head that secures in place, so they won’t start if you bump them on accident.
Momentary actuators can only be locked in the off position. Maintained actuators can be locked in any position.
Optional mounting clips accept up to four contact blocks.
