Cable-Pull Emergency Stop Switches
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.
