    Immediately cut power by pulling a cable. These switches are often used to turn off production lines and material handling systems in an emergency. All have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch.
    2 Directions—Two-direction switches can be used with tension springs (not included) to open contacts and stop machinery if the cable breaks.
    Emergency Stop Button—Switches with an emergency stop button can be shut off either by their button or cable. They’re often installed where equipment may block access to the cable.
    Power Indicator—Switches with a power indicator illuminate when the cable has been pulled.
    Tension Indicator—Switches with a tension indicator let you visually confirm that tension is set correctly in the system.
    Switch Installation Kits—Accessory kits (sold separately) simplify the installation of a new switch.

    Down Pull

    Any-Direction

    Pull

    Tug the hanging rope to actuate these switches. They're rated NEMA 4 to protect against washdowns.
    Down Pull—Pull-down switches only actuate when you pull the rope directly down.
    Any-Direction Pull—Pull-any-direction switches actuate even when you pull the rope at an angle. These are good for spaces where you can't mount the switch directly above your workstation.

    Safe to use near ignitable gases and dust, the housing on these switches seals in anything that could ignite flammable material. All are UL listed and CSA certified for use in hazardous locations. Yank the cable anywhere along your line to quickly cut power in emergencies. They have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch. Use the tension indicator to visually confirm that they’re reset correctly.

    Cable-Pull-Actuator Emergency Stop Switches with Restart Switch

    Tug the cable to stop your line, then follow it back to the restart switch. Typically separate devices, the stop and reset controls are in one compact unit. As a secondary shutdown option, a push-button stop switch is also built in. A secondary push-button stop switch ensures you can halt equipment immediately, even when the cable is out of reach. Because they let you control circuits from a distance with a quick tug, these cable-pull stop switches are often used to turn off production lines and material handling systems. To notify your team on the floor that you’ve stopped equipment, a power indicator lights up when you pull the cable.
    Use the tension indicator to confirm that cable is set up correctly. Circuits remain open until you tension the cable and hit the restart button. Cable is not included.

    Style D

    No need for wiring—these lights plug into a standard wall outlet. Also known as shop lights, they suspend from your ceiling or can be surface mounted with the included hardware. Their smooth, frosted lens disperses light and reduces glare. Since the lens is polycarbonate, these lights stand up to bumps. ETL listed for use in damp locations, they also withstand humidity and moisture.
    Style C—Styles B-D can be chained together by plugging their power cord into the power outlet on the previous light. Style C are the brightest plug-in ceiling light, so they’re ideal for large areas.
    Style D—Styles B-D can be chained together by plugging their power cord into the power outlet on the previous light.
    Neutral Light—Neutral lights are often found in workspaces.
    Cool Light—Cool lights highlight white and blue tones. This is ideal for inspection areas, workshops, and other areas that require high visibility.
