ABSTRACT:
The load-isolating switch comprises two coaxial electrodes 1 and 2, which are mechanically connected by an interposed insulator 3. A cam 4 is provided on the insulator 3 and is spanned by at least one contact bridge 5, which is axially displaceable by an axially displaceable slider 10, which has coupling elements 13, 14 for engaging the or each contact bridge 5. In one position the or each contact bridge 5 is in contact with both electrodes 1 and 2. The or each contact bridge is adapted to slide up on an inclined surface 4a of the cam to disengage the contact bridge 5 from one of said electrodes and is movable to a second position in which said slider is disengaged from at least said one electrode.
