Abstract (en)
[origin: US5786552A] PCT No. PCT/EP95/00855 Sec. 371 Date Sep. 25, 1996 Sec. 102(e) Date Sep. 25, 1996 PCT Filed Mar. 8, 1995 PCT Pub. No. WO95/24724 PCT Pub. Date Sep. 14, 1995The invention concerns a switching arrangement for load change-over switches of step switches and for selector switches, wherein two switching contacts movable in two directions are present. The first switching contact is in the form of a main switching contact and is connected to the load derivation by means of a first vacuum switchgear cell. The second switching contact is in the form of a resistance switching contact which is likewise connected to the load derivation by means of a series connection comprising a second vacuum switchgear cell and a transition resistor. Both the main and the resistance switching contacts can be moved independently of one another and without mutual coupling or influence. The main switching contact always reaches the new fixed contact abruptly and independently of the switching direction before the resistance switching contact leaves the previous fixed contact.
