Abstract: A DIP rotary switch comprising a housing within which rotatable members such as a rotor and a disc are disposed around a pivot protruding from the center of a molded base which horizontally sandwiches a one piece plate terminal manufactured by a punching process. A contact segment of the plate terminal is bent first upward along a step of a hollow disposed at the surface edge of the base and then pressed down to be located along the slot arranged at the surface thereof, while a lead foot is bent downward to a right angle by touching on a step of a hollow arranged at the under surface of the base.
