ABSTRACT:
A rotary operation type miniaturized electronic component for use in video and audio electronic appliances, etc., including a casing formed with an opening and a rotary member. In the electronic component, a metal plate is integrally molded with the casing at a bottom face of the casing and then, is cut so as to form two conductive plates, two terminals for external takeoff, and two legs for mounting the casing on a printed circuit board, while a metal sheet is integrally molded with the rotary member and then, is cut so as to form two rotary sliders. Thus, it becomes possible to perform automatic soldering of the electronic component to the printed circuit board.
