ABSTRACT:
An improved bearing and journal construction is provided for a high-voltage disconnecting switch of the type having supporting insulators and a rotatable crank-arm arrangement, with the operating thrust of the crank-arm being supported by simplified bearing discs running in a journal, the improvement residing in the fact that the hinge member about which the switch-blade pivots is separate from the journal member which bridges the hinge supporting insulator to the rotating insulator, and that the foregoing separation allows the journal member to be stamped out of plate material resulting in considerable economy over the cast construction known to prior art. A preferred bearing arrangement locates the discs under the crank-arm so that traditional machining of a bearing race on the crank-arm is eliminated for further economy.
