Wu, J L; Scherbarth, D W; Marschik, D

A switch is described for switching direct current comprising: a rotor having a generally cylindrical conductive element; the conductive element having first and second portions, where the first portion includes a continuously conductive external surface; a pair of insulating members fixed at angularly spaced locations on the second portion such that sections of the conductive element and the insulating members alternate along a generally cylindrical surface of the second portion; a first pair of angularly spaced retractable brush members extending radially inward toward and axially along the conductive external surface of the first portion of the conductive element, for making sliding electrical contact with the first portion of the conductive element; a second pair of angularly spaced retractable brush members extending radially inward toward and axially along the generally cylindrical surface of the second portion of the conductive element.
