5 Functional description
The holding force of the inserted pressure springs is directly applied to the release flange and
fixes the switching axis, which is positioned by three pins, in the zero position. In the event of
collision, the switching axis tips over, the release flange pushes the spring plate toward the base
of the housing and the trigger is actuated by the spring plate's actuating mechanism. The trigger
is an NC switch. The applied switching voltage is interrupted.
