Abstract
A variable resistor has an insulating substrate plate, a resistance body formed on the substrate plate and a slider adapted to slide along the resistance body. The resistance body is formed in a winding pattern to provide a larger range of variation of resistance for a given stroke of the slider. The slider has a plurality of contacts adapted for sliding along the resistance body so that at least one of the contacts is kept in contact with the winding resistance body so as to provide a linear change of the output of the resistor.
