Loose key, fixed (GD2)

Electrically lockable key switch with a locking force of 2,000 N. The switch has a status indication that shows whether the switch is locked or unlocked. It also has a rotatable head which gives four different key inputs. In the event of a power failure, the breaker can be forcibly opened using an override key. The control signal for unlocking the breaker should come from a standstill monitor (see section "Safety modules") which then unlocks the breaker and releases the key when the machine is in a safe position.
