Switch device for use on circuit board

A one-piece stamped and formed switch device which is intended for mounting in holes in a circuit board as a noramlly closed circuit board switch, said switch device comprising:

• an elongated flat base portion having spring arm mounting means extending therefrom at one end thereof, said spring arm mounting means extending substantially normally of said base portion in a first direction,
• a flange extending normally of said base portion at the other end thereof in a second direction which is the opposite direction from said first direction, said flange having an integral contact post extending beside said flange and projecting in said one direction past the plane of said base portion,
• a cantilever spring arm disposed beside said base portion in a plane which extends normally of the plane of said base portion, said spring arm having a fixed end which is integral with said base portion at said one end, said spring arm extending beside said base portion and past said flange, said spring arm having a resilient bias towards said flange,
• a stop extending from said one side edge of said base portion intermediate said ends, said stop being against said spring arm and restraining said spring arm against its resilient bias and thereby maintaining said spring arm in spaced relationship to said flange whereby,
• upon insertion of said spring arm mounting means and said contact post into circuit board holes, soldering said spring arm mounting means and said post to conductors on the underside of said circuit board, and thereafter removing intermediate portions of said base including said stop, said contact post will be electrically isolated from said spring arm mounting means and said spring arm will move against, and be resiliently biased against, portions of said flange thereby providing a normally closed switch on said circuit board.
