Choosing an Electrical Switch

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.

Aluminum Enclosed Push-Button Switches
A lightweight yet durable alternative to stainless steel enclosed switches, these aluminum enclosed switches withstand corrosion, oil, and washdowns. They can mount directly to a wall when there’s not enough room in an electrical panel. The enclosure has knockouts so you can easily connect it to conduit fittings and cord grips.
Switches with a lockout can be locked using a padlock.

Hazardous Location 30 mm Panel-Mount Push-Button Switches
Actuate these switches with a quick push. A housing seals in anything that could ignite flammable material, so you can use them where ignitable gas and dust may be present. You’ll know they’re safe because they meet NEC Class I Div. 2, Groups B, C, D for hazardous locations. Install them in a standard panel cutout.
Mushroom switches have a button that sticks out from the panel. Because they’re easy to identify and actuate, these switches are often used to stop equipment. They have a twist reset, so they’ll return to their starting position when you rotate the button.
Switches come with a contact block for each number of circuits they control. Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.

Hazardous Location 30 mm Panel-Mount Key Switches
Designed for use near ignitable gases, fibers, and dust, these switches have a housing that seals in anything that could ignite flammable material. You’ll know they’re safe because they’re NEC Class 1, Division 2 Groups A-D and NEC Zone 1 Groups IIC-IIA certified for hazardous locations. These switches require a key to turn circuits on or off, preventing accidental actuation and limiting access to sensitive equipment. Since they’re keyed alike, all open with the same key. Install them in a standard panel cutout.
Switches that control two circuits come with a contact block for each circuit.
Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.
