Abstract

A safety switch has an LS (line protection) and an FI (fault current protection) section. The switch lock of the LS section has a catch support lockable by a catch which, for tripping (in the event of an overcurrent), works with a bimetal release and a magnetic release. The switch lock of the FI section has a catch (31) and a catch support (32) associated with a permanent-magnet release with a release push-rod (51). The switch bridge of the LS section and that (36) of the FI section can pivot about a common axis (60) in the safety switch housing. The switch bridge of the LS section is coupled to the switch bridge (36) of the FI section for combined movement by a pin (7) which is inserted into a switch bridge support (35) for the switch bridge (36) of the FI section. In the catch support of the switch lock of the LS section there is a pin (69) associated with the catch (31) of the FI section in such a way that it abuts on the pin (69) when pivoted in the event of a fault current. Thus the catch support of the LS section pivots to release the switch lock of the LS section.
