ABSTRACT:
A variable resistor and a method for manufacturing the same is disclosed in which the variable resistor includes a casing having a bottom wall and a plurality of sidewalls extending from the bottom wall to define an opening of the casing. An insulating substrate is provided having a first surface formed along the bottom wall of the casing and a second surface opposite the first surface facing the opening of the casing. A curved resistor layer and a centrally disposed collector electrode layer are formed on the second surface of the insulating substrate. A rotor member is rotatively disposed within the casing such that its rotation axis extends through the centrally disposed collector layer. A slidable member is connected to the rotor member and is slidably connected to the curved resistor layer and the collector electrode layer for electrically connecting the curved resistor layer and the collector electrode layer. The rotor member is secured within the casing by the sidewalls which are molded to extend inwardly towards the rotational axis defined by the rotor member.
