Abstract

A new electromechanical device for interleaving resistances in an electrical circuit, characterized in that it essentially comprises the assembly constituted by a multiplicity of flexible metal sheets with one of their respective ends mounted fixed on the armature of the apparatus while the other free end of each sheet is carrier of a contact able to cooperate, in a position of the sheet, with a fixed contact disposed opposite said free end, as well as a displaceable part, independent of the multiplicity of sheets, but arranged in the vicinity thereof, which has the particularity to be provided with stepped actuating means for the sheets, so that, when the item changes position, said means act stepwise on the successive flexible sheets changing the equilibrium position thereof and also existing, in combination with the elements above, some electrical resistances dis conventionally, with their respective electrically connected ends either to the mobile contacts of the flexible sheets, either to the fixed contacts and, where appropriate, to the two series of contacts at the same time, there also being elastic means, such as springs and springs which has a tendency to keep the piece displaceable in an extreme position of its travel.
