Opaş cam switches with detachable shafts mounted on the panel base prevent the panel door from being opened without setting the cam switch on the panel to the off position. Once the cam switch is turned off, the panel door can be opened, allowing safe maintenance and repair work inside the electrically isolated panel.

Bypass cam switches produced by Opaş for elevators provide a safe working environment during maintenance with their specially designed spring-loaded protective covers. Additionally, the special cam switch boxes are compatible with small padlocks, preventing unauthorized access to the cam switches used in elevators.
