Abstract

The invention relates to an on-load isolating switch of a high-tension switching unit (three-phase current switch) consisting of three switching elements (11, 12, 13) which in each case connect two electrical contacts and are provided with a latching device, which switching elements can be moved from the switched-on position into the switched-off position and vice versa by means of an insertion and extraction tool (manual snap-action mechanism). 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 three switching elements (11, 12, 13) are connected to one another by means of a dielectric bridge (10), such that, on operation of one of the switching elements (11 to 15), all three switching elements (11 to 13) can be switched in unison. In a preferred method, only the centre switching element (12) is provided with a latching device (24) and can be operated by means of the tool (50). <IMAGE>
