ABSTRACT:
A trimmer capacitor comprises a metallic plate member which is generally U-shaped, and an elongate conductor member which is to be located inside the metallic plate. Both the metallic plate member and the conductor member can be fixed to a printed circuit board. By bending the conductor member to displace it inside the metallic plate member, the electrostatic capacitance formed between the metallic plate member and the conductor member can be varied.
