Mechanical Interlocks

KIRK® mechanical interlocks mounted directly on equipment act as a physical barrier to electrical switches and power buttons, ensuring the state of power cannot be mistakenly changed. Most commonly found in electrical switchgear and machine guarding applications, the mechanical interlock ensures that once the equipment is switched into the desired position indicated by the end user, the bolt is extended, and key removed, blocking the switch from changing state until the procedure is reversed.
