Abstract
A multiple slide resistor suitable for use as a tandem resistor in a stereo system is disclosed. The slide resistor comprises a housing having a slide slot in which a slide bar is arranged to slide along a guide rail. The resistance and collector elements of each resistor are mounted upon a conductive layer on one side of a base plate which forms a closure for the housing. A shielding wall is provided between the resistors for electrically isolating them. The wall is electrically connected to the conductive layer of the base plate so as to achieve a desired cross talk attenuation.
Claims5
In a multiple slide resistor having a base plate that forms a bottom closure of a resistor housing provided with a slide slot, resistor units each including a resistance element and a collector element associated with said resistance element being attached to said base plate, each resistor unit being separated electrically from the other by means of a shielding, and a movable slide element common to all the resistor units and upon which a number of pairs of brush springs corresponding to the number of resistor units is fastened to produce an electrical connection between the resistance element and the collector element of each resistor unit, the improvement comprising said base plate having a conductive coating on at least the side thereof upon which the resistance and collector elements are located, said coating being electrically connected with the shielding, said shielding projecting above the pairs of brush springs.
