  • Dual track resistor element having nonlinear output
    Patent number: 4435691
    Abstract: A variable resistor element (10) comprises two thick film resistance layers or tracks (12, 14; 40, 50) electrically insulated one from another and on an insulating substrate (11). The thick film resistance layers (40, 50) may consist of the same resistance composition and thereby have the same resistivity, but the paths (40, 50) having different widths to effect different resistances; or, the widths of the resistance layers (12, 14) may be the same but the layers (12, 14) comprise different resistance compositions having different resistivities. An electrical contactor (20) has flexible fingers (22) wipably and respectively engaging the surface of each resistance layer (12, 14; 40, 50) to complete a circuit across the tracks (12, 14; 40, 50) and through the terminals (16 and 66) of the respective layers.
