Abstract
A diaphragm for the contact insulating housing of a mechanically operated high voltage switch. The diaphragm has a central portion through which the shaft from the mechanical operating mechanism to the movable contact passes. The walls of the diaphragm about the central portion are mechanically joined or chemically bonded to the shaft. The diaphragm is made of such materials, is dimensioned and configured so that the diaphragm moves with the shaft and prevents relative motion therebetween. The outer rim of the diaphragm is mechanically joined or chemically bonded to the switch housing. The quality of the diaphragm and the seals permits them to withstand the application of the full operating voltage of the switch.
