Abstract

The load selector has a cylindrical oil chamber (1) with a stage switching head (2) and a base. The cylinder is produced from an insulating material that has for each phase a series of fixed stage contacts (4) that operate in relation to moving contacts within the cylinder. The moving contacts are coupled to a central switching tube that has a drive gear. At the side of the cylinder is a pre-selector that is supported on brackets (8,9) and has a switching shaft (10) that carries pre-selector contacts (12). A moving contact (13) is located on the water side of a wall section (11).
