| Zusammenfassung: | A flat snap-action push-button switch comprising a sheetmetal spring with two elongated slots dividing the sheetmetal member into three coherent strips, is disclosed. The center strip is extended beyond the point of junction of the strips, and carries contacts which cooperate with fixed contacts on a printed circuit board. By depressing the center strip the spring snaps over thus opening one contact and closing another. The switch is particularly suited for use with key boards of electronic pocket calculators. |
