ABSTRACT:
A seesaw manipulation-type variable resistor is provided which has a linear sliding-type variable resistor unit. A U-shaped groove in a below-extended arm of a manipulation key smoothly interlink with a coupling member of a linear sliding-type variable resistor. A position restoring leaf spring is provided touching protrusions under both ends of the manipulation key, to give the manipulation key a force for restoration to its neutral position.
