Abstract:
A variable resistor comprising:a casing having an opening and defining an internal cavity;a cover having a shaft hole, a through hole, and a terminal hole, said cover attachable to said casing so as to cover said opening;an insulating substrate held by said casing and extending outward from said internal cavity through said cover via said through hole, said insulating substrate having an end portion adjacent to said cover and an end portion disposed opposing said end portion adjacent to said cover, said insulating substrate having a terminal pattern formed on said end portion adjacent to said cover and a resistor connected with said terminal pattern and extending from the adjacent end portion;a slider in sliding contract with said resistor;a slider receiver adapted to receive said slider, said slider receiver disposed in said internal cavity and movable in an axial direction parallel with said insulating substrate;a shaft movably disposed in said shaft hole, said shaft operative to move said slider receiver in said axial direction and having a projection in contact with an inner surface of said cover around said shaft hole, said projection operative to prevent said shaft from being extracted from said shaft hole;a return spring disposed in said internal cavity operative to restore said slider receiver in the axial direction in opposition to said shaft; andan external terminal held by said casing, said external terminal having a first end portion protruding outward from said cover through said terminal hole and a second end portion protruding from an outer surface of said casing, said first end portion of said external terminal electrically connected with said terminal pattern by a clip terminal;wherein said clip terminal has a first arm extending along said insulating substrate in resilient contact with said terminal pattern, a second arm extending along said external terminal in resilient contact with said external terminal, and a base portion for connecting end portions of said first arm and said second arm, said first arm and said second arm both adjacent to said cover.
