Locked out of a key switch in your control system? Pick up this replacement key from Eaton. It's coded to MS 2 lock mechanisms, so it only actuates compatible key-operated switches (such as 893-8580), found in settings like power distribution networks and processing plants. Thanks to its durable metal construction, the key keeps its shape through heavy handling. The round head is easy to grip, even when you're wearing gloves, and there's a pre-drilled hole so you can slot it onto a keyring.

• Marked with lock mechanism coding so you can clearly spot it on busy key chains
• Sold individually for close system access control

The key latches to its switch until it moves into a releasable position, minimising the risk of accidental removal and boosting machine safety.

Specialist keys like this one are precision-shaped, with notches along the length of the shaft rather than on the edges. This ensures they can't be commercially cut and used without authorisation.
