Abrasion-proof brush spring contact structure for stabilizing and permanently reducing contact resistance between a brush spring contact and a potentiometer path has a retaining element to match a long-term use.

摘要

Metal alloy contacts consist of different precious metal alloys. The different metal alloy contacts are made up of wires and ribbons and can be arranged individually, in series, in sequences or in packets in series or sequences. The contacts use materials of different hardness and springiness. They also have different thicknesses and shapes of material as well as different contact surfaces.
