ABSTRACT:
An isolating switch apparatus, includes an encapsulation having at least one disconnection point and a plurality of contact points corresponding to a given number of phases therein, a plurality of phase conductors at least partially disposed in the encapsulation for a plurality of phases, first and second connection pieces connected to the phase conductors in the encapsulation for each contact point of each phase, the first and second connection pieces being partially overlapped, mutually spaced apart and substantially mutually parallel, a contact piece disposed on the second connection piece, an insulated drive shaft passing through a hole formed through the first connection piece, the drive shaft being overlapped by the second connection piece, and a contact blade attached to and rotatable by the drive shaft into a switched-on position in which the contact blade is substantially perpendicular to the first and second connection pieces, is disposed between the first and second connection pieces, and contacts the contact piece.
