摘要

Sliding contact system (I) for an adjustable electrical resistance comprises at least one slider and with several resistance path bounded strip conductor for the slider on the carrier, where at least surface of the carrier (1) and the strip conductor (2) for the slider comprises either an adhering and dry grease film forming lubricating lacquer or a dry lubricant film. Sliding contact system, for an adjustable electrical resistance, comprises at least one slider with several resistance path bounded strip conductor for the slider on the carrier, where both at least a layer of the slider as sliding contact and the strip conductor comprise at least partially of noble metal or a multicomponent system based on noble metals, where at least surface of the carrier (1) and the strip conductor (2) for the slider comprises either an adhering and dry grease film forming lubricant lacquer or a dry lubricant film. Independent claims are also included for: (a) a method for the preparation of the printed circuit board as carriers bounded with a resistance path and at least partially either of a noble metal or a multi component system based on the noble metal consisting strip conductor for the slider of (I), comprising applying strip conductor and resistance path respectively as paste on the carrier after each other and hardening, where at least on the surface of the carrier and the strip conductor for the sliding contact of the slider either adhering grease film of a lubricating lacquer or a lubricating film is applied by spraying or dipping; and (b) use of adhering and dry grease film formed lubricating lacquer or a dry lubricating film for an electrical sliding contact system for an adjustable electrical resistance with at least a slider and with several resistance path connected strip conductor for the sliding contact of the sliders on a carrier, where both at least one layer of the sliding contact of the sliders and the strip conductor comprises at least partially a noble metal or a multi component system on basis of noble metals, that the lubricating lacquer or the lubricating film is used on the strip conductor for most extensive abrasion-free contact and for the assurance of an electrical connection between at least one strip conductor and the slider.
