KAPACITET TANGENTKONTAKT MED OVERSTYRINGSMEKANISME PAA EN BEVAEGELIG PLADE

A capacitive keyswitch is formed with a fixed horizontal plate that is imbedded in a horizontal printed circuit board below an overlaying dielectric layer and a moveable cantilever mounted plate that is hinged to the printed circuit board so as to project upwardly at an acute angle. When a plunger is actuated, a portion of it presses down on an overtravel mechanism that is formed from the moveable plate which causes the moveable plate to assume approximately a parallel position with respect to fixed horizontal plate, thereby changing the capacitance of the switch and actuating the switch. The overtravel mechanism consists of a tab cut out of a bent-up portion of the moveable plate so that the tab is bent along an intersection line formed by the intersection of the plane or moveable plate and the plane of the bent-up section.
