In modern electrical installations, operational safety, controlled access, and reliability are just as important as performance. One of the most effective components combining all these requirements is the locked cam switch. By integrating precise rotary switching with a mechanical locking mechanism, locked cam switches ensure secure circuit control while preventing unauthorized or accidental operation.
SEZ offers a dedicated range of cam switches with EuroLock, engineered to meet the highest standards of industrial safety, durability, and operational reliability.

What Is a Locked Cam Switch?
A locked cam switch is a rotary electrical switch that allows the operator to mechanically lock the switch handle in a selected position. Once locked, the switch cannot be rotated until the lock is intentionally released using the appropriate key.
This functionality is particularly important in applications where circuits must remain safely isolated during:
Maintenance and servicing
Inspection procedures
Emergency shutdowns
Unlike standard cam switches, lockable cam switches provide an additional level of protection by securing critical positions, such as OFF or predefined operating modes.
