ABSTRACT:
The switch includes a rotatable electrically insulating carriage having first and second contactors mounted thereon and facing in opposite directions from the path of the carriage, for a sliding engagement with first and second sets of fixed contacts. The contactors are biased in opposite directions, toward the contacts, by an electrically insulating switch assembly, mounted in a cylindrical opening in the carriage, and comprising a cup-shaped insulator having a cylindrical portion slidably mounted in the cylindrical opening. The insulator having a cup-shaped spring nest therein, for receiving one end of a coil spring. Biasing forces are exerted against the contactors by an end portion of the insulator and the opposite end of the coil spring. The cup-shaped insulator guides and locates the coil spring while obviating any electrical connection between the first and second contactors.
