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 OFF
with a test handle, the test auxiliary contacts change posi-
tion. The main contacts remain open.
