Series 61 Emergency Keylock Stop Switch


Emergency keylock stop switches are operated by simply pushing on the front operator to immediately break a circuit. They then may be released to reactivate the circuit using a key.

EAO emergency stop switches meet the new EN 418 directive for "foolproof" operation. They prevent teasing the actuator which could result in premature or unreliable operation and eliminate blocking the emergency stop operation by lodging foreign objects behind the actuator.

Standard key code is 1001.
Other numbers available on request.
Spare keys: Part No: 14-978
(state 4 digit key code)
