Abstract
Abstract A layer voltage divider of the type having a resistance web and one or more additional impedances attached thereto, the divider comprising : one or several impedances on a supporting plate, laterally extending tabs provided on the impedance, an insulating layer covering the impedance or impedances to the exclusion of their taps, a resistance web being placed on the insulating layer and having taps, the taps of the resistance web being conductingly connected to the taps of the said one or more impedances.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
In a layer voltage divider: a supporting plate; a resistance web being applied on said plate and having at least one connecting tap; at least one additional impedance being provided with a laterally projecting connecting tap and apPlied to said plate; an insulating layer being interposed between said resistance web and said impedance to the exclusion of their said connecting taps; and said tap of said resistance web and said tap of said impedance conductingly overlapping each other.
