30.5 mm key-operated switches
Key-operated switches are equipped with a lock for safety reasons. The switching operation
(in this case, the actuation of contact modules) can only be performed by an authorized
group of persons who have access to the relevant key. Up to 3 switch positions can be
temporarily or permanently selected using a key-operated switch. The 30.5 mm key-
operated switches are suitable for installation on a front plate with a maximum thickness of
4 mm.
The metal holder (3SU1550-0AA10-0AA0) must be used when mounting.
In addition, the adapter (3SU1950-0KJ80-0AA0) for actuators and indicators for flat mounting
must be mounted between the front plate and the holder. The adapter is included in the
scope of supply, but can also be ordered as a separate item.
Key-operated switches are available in different variants according to the following features:
● Switch positions
● Key removal positions
● Color of actuators
30.5 mm diameter key-operated switches
