摘要：The invention relates to an on-load isolating switch of a high-tension switchingunit (three-phase current switch) consisting of three switching elements (11, 12, 13) whichin each case connect two electrical contacts and are provided with a latching device, whichswitching elements can be moved from the switched-on position into the switched-offposition and vice versa by means of an insertion and extraction tool (manual snap-actionmechanism). In order to be able to switch off or on all three switching elements (11, 12,13) and thus all three phases (RYB) of the supply network simultaneously, the threeswitching elements (11, 12, 13) are connected to one another by means of a dielectricbridge (10), such that, on operation of one of the switching elements (11 to 15), all threeswitching elements (11 to 13) can be switched in unison. In a preferred method, only thecentre switching element (12) is provided with a latching device (24) and can be operatedby means of the tool (50).
