ABSTRACT:
In a method of manufacturing a switch base according to the invention, blanked members are prepared, each having a common strip formed at a lower part thereof, a plurality of finger-shaped pieces extending from the common strip, fixed contact portions formed on distal end portions of respective ones of the finger-shaped pieces, and terminal portions situated between respective ones of the fixed contact portions and the common strip. Next, indentically shaped blanked members are superimposed in such a manner that the fixed contact portions thereof are spaced away from one another, and the blanked members are assembled together with the fixed contact portions being arrayed in a plurality of rows and the terminal portions being arrayed in a single row. Thereafter, a resin is molded between the fixed contact portions and the terminal portions to form a base, and the common strips are cut away to manufacture a switch base.
