ABSTRACT:
A variable capacitor for use in electrical and electronic equipment which includes a stator disposed on an insulating base, a stator terminal lead having an electrode portion fixed to the stator and a terminal end extending through the insulating base. The variable capacitor includes a metallic rotor rotatably disposed on the stator through a dielectric plate, a rotor terminal lead having a resilient spring portion disposed on the rotor and a terminal end extending through the base, and an insulating cap of hollow cylindrical shape fitted over the resilient spring portion of the rotor terminal lead. The insulating cap is rigidly connected to the base to form the variable capacitor of compact size with sufficiently large electrostatic capacity.
