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.
Switches with lockout latch when you depress the button and can be locked in that position using a lockout or padlock with a 9/32" shackle diameter.
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.
