The switching element and actuating keys for the
safety interlocks are not connected to each other,
but are functionally
combined or separated when
switching. The actuating key is separated from the
basic device when the guarding is opened. In
doing so, the normally closed contacts are opened
and the normally open contacts are closed in the
safety interlock.
