Choosing an Electrical Switch

One Direction

One Direction with Power and Tension Indicator

Two Direction

Immediately cut power by pulling a cable. All have positive force, snap open contacts that will open the circuit when actuated even if a spring fails or the contacts stick. Cables must be held in position under tension.

Two-direction switches can be used with tension springs (sold separately) to open contacts and stop machinery if the cable breaks.

Switches with power indicator illuminate when the cable has been pulled.

Switches with tension indicator make it easier to set the correct cable tension.

Accessory kits (sold separately) simplify the installation of a new switch.

Cable-Pull Switches

Connect these switches to a cable to control circuits from a distance. They're typically used to turn off production lines and material handling systems. Equipment will not start up again until switch is manually reset. Mount in any position.

Pull Cords for Light Bulb Sockets

To lengthen a pull-chain light switch, these cords have a bead chain connector that snaps onto beaded chain. They have a braided construction and a bell-shaped end fitting so they won't unravel or fray.

Small-Room Ceiling Lights

Ceiling Light with Pull Chain

Update standard outlet boxes in closets, hallways, and storage rooms to use LED light. These ceiling lights are good for tight spaces because they have a lower profile than standard bulbs and a polycarbonate housing that shields them from impact. Their LED bulb lasts longer, is more efficient, and generates less heat than other light technologies. They produce warm light, which looks like the light from incandescent bulbs. All meet NFPA 70 safety standards for lights in clothing closets.
