ABSTRACT:
A telescoping disconnect switch for isolated phase bus has a cylindrical movable conductor having a plurality of individual contact assemblies each comprising a contact finger and an axially loaded spring fixedly attached thereto. The contact assemblies are circumferentially arranged about the movable conductor and are removably secured between a contact holder ring and a spring retainer ring. A plurality of stabilizer pads are symmetrically arranged around the circumference of the movable conductor between the contact fingers and are fixedly secured to the movable conductor to stabilize the contact assemblies and align the conductor as it moves to open and close the circuit.
