Abstract (en)
[origin: EP0780867A2] A vacuum switching device has a junction (40; 45) at which a housing (10, 23; 10, 22, 24, 60) of said switching device, a first switching component (11, 13; 12, 14) and a second switching component (15; 16) meet, said junction (40; 45) having a vacuum on one side and a gas on the other, said housing and said first and second switching components comprising locating means (41, 42; 43, 44) for allowing accurate location of said first and second switching components with respect to each other and with respect to said housing. The switching components are, for example, the stem (13; 14) of a fixed or moving contact and an end-stub (15; 16) for making electrical connection between the contact and external equipment. The locating means are, preferably, a male "peg" (41; 43) on the stem and a bored hole (41; 44) in the end-stub, the peg fitting into a corresponding hole in the housing at that point. <IMAGE>
