MK Elecric offers key-controlled switch

MK Electric now offers a key-controlled switch for several ranges of switches and sockets. The Masterseal, Metalclad Plus, Edge and Albany ranges are all available with key-operated locks to prevent unauthorised tampering with the power supply.
The key can be removed from the lock in either the on position or the off position. The universal lock allows one key to operate a number of devices. All products have backed-out captive terminal screws and require one size of screwdriver for installation. Metalclad Plus and Masterseal versions are supplied with a mounting box.
