30 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches are rated for protection from low-pressure streams of water and oil/coolant spraying. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. Mount them in a standard panel cutout.
Illuminated switches are visible in low light. They include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Turn twist switches back on by twisting the button and pull switches by pulling it. Add an optional lockout (sold separately) on either kind to cover the button and prevent changes to its position.
Additional contact blocks (sold separately) can be added to control more circuits or replace the included contact blocks.

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.

Harsh Environment Potentiometers
Rated NEMA 13, these potentiometers protect against debris and splashing oil and coolant. Also known as variable output switches, they vary electrical flow to control speed, volume, and light intensity.
NEMA 4X rated potentiometers withstand weather, washdowns, and corrosion.
