<p>A keyswitch includes an insulative substrate (5, 5 min ) and a conductive spring reed (1, 1 min ). First and second conductive paths (6 and 7, 6 min and 7 min ) are formed separately on the upper surface of the substrate (5, 5 min ). The reed (1, 1 min ) has an inclined long leg fixed on the first path (6, 6 min ), an inclined short leg positioned separately near the second path (7, 7 min ), and an upright stop (4, 4 min ) extending downward from the reed (1, 1 min ). The long leg, short leg, and stop (4, 4 min ) are all integral with the reed (1, 1 min ). The lower end of the stop (4, 4 min ) is above the lower end of the short leg. When the reed (1, 1 min ) is depressed, the short leg contacts the second path (7, 7 min ) to form a conductive path between the first and second paths (6 and 7, 6 min and 7 min ), and then the stop (4, 4 min ) contacts the substrate (5, 5 min ) so that the reed (1, 1 min ) no loner moves downward.</p> |
