摘要： There is provided switch apparatus (10) for interrupting an AC distribution grid and consisting of a single break switch assembly contained in a sealed enclosure (12) filled with sulphur hexafluoride gas (13). The switch assembly is interposed between a line conductor (14) and a load conductor (15) led into the enclosure (12) by gas tight insulator assemblies (16). The line conductor (14) is terminated by a fixed contact (21) having embedded therein a cylindrical rare earth metal magnet (23). The load conductor (15) is terminated by a moving contact assembly (24) including a contact mounting body (25) having pivotally mounted thereto an elongate main contact arm (26) having contact plates (27) adapted to electrically engage a copper-tungsten arcing fixed contact portion (33) of the fixed contact (21). Pivotally mounted between and electrically common with the contact plates (27) is an integral arcing contact assembly (37) comprising an arcing contact (40) having a cylindrical rare earth metal permanent magnet (41) embedded therein and an arcing contact arm (42).
