DISCONNECT SWITCH UTILIZING INSULATING BASE HAVING INTEGRALLY FORMED INSULATOR BUSHINGS

摘要

A hook disconnect switch having a base member formed of an insulating material and insulator units integrally joined thereto. Two insulators are aligned at an angle relative to one another and support the jaw and pivoting end of a switch blade. The orientation of the insulators significantly reduce cantilever forces imposed by horizontal incoming lines upon the insulators. The base member provides a means for rigidly positioning and supporting the hook switch assembly, as well as enhancing the dielectric strength of the insulators. The design and orientation of the insulators further reduce overall switch size and considerably reduce the effect of contamination for all mounting positions of the switch.
