Abstract: A variable resistance control employs a contactor wipably engaging a resistance element and a collector supported by a pair of split housing sections. Positioning tabs extend from the resistance element and collector into undercut portions in the housing section. Control operating means for moving the contactor relative to the resistance element is positioned in a slot in the housing and provided with parallel longitudinal grooves receiving the side walls of the slot. A contactor having a pair of spaced bars has a continuous strip connecting the spaced bars and extending through an opening in the control operating means for engaging the resistance element. The contactor resiliently biases the control operating means against one side wall of a channel formed in the bottom wall of the housing. End walls of the housing are provided with a groove extending therearound such that a U-shaped mounting bracket having a pair of spaced legs and a connecting portion is disposed in each of the grooves. The legs have ends bent toward each other to firmly engage the housing and maintain the housing section in assembled relationships.

Abstract: A high voltage electrical resistor comprises a resistive path supported on a dielectric hollow cylindrical substrate, termination means electrically connected to the resistive path, an insulation system and a heat dissipation system. The high voltage end of the substrate is spaced from the wall of an insulative jacket by means of projections extending radially inwardly from the wall. The low voltage end of the substrate is spaced from the wall of the jacket by means of a heat dissipating mounting member. The termination means include insulated lead wires electrically connected to the resistive path with a lead wire adjacent the high voltage end of the substrate passing through a tubular projection of the jacket. A heat shrunk sleeve forms a tight seal between the tubular projection and the lead wire. Dielectric material fills the space between the substrate and the jacket forming a moisture impervious barrier around the resistive path and improving the dielectric strength of the resistor.
