The magnetic limit switch has one closing and one opening contact. The contacts are monitored by a
safety plc. To avoid unauthorised operation of the switch it is only possible to actuate the switch with

the safety magnet gives a fixed green light the connection is ok. When there is a red light there is no
connection.
