Handle indications and functions

• The handle indicates the position of the main contacts of

the switch with complete reliability in all situations.

If the contacts are welded together, the handle

does not reach the OFF-position but remains

between ON and OFF, maintaining the door

interlock and preventing padlocking.

• When operating the switch to the Test-position

with a test handle, the test auxiliary contacts change posi-

tion. The main contacts remain open.
