Zusammenfassung:A switching device (10) comprises a first and a second fixed contact (55, 56), a contact bridge (40), a first and a second movable contact (45, 46) arranged at the contact bridge (40), a contact spring (31), a contact bridge carrier (30), a housing (35) and at least one stopper (71, 72). The contact bridge carrier (30) is movable and is coupled to the contact bridge (40) via the contact spring (31). The at least one stopper (71, 72) is connected to the housing (35) and is configured to limit a movement of the contact bridge (40) in case of a short circuit. The switching device (10) also comprises a magnetic drive assembly with an electric coil (48), a magnetic core (50) and an armature (47), wherein the armature (47) is movable and is connected to the contact bridge carrier (30).
