Abstract

Electric button for calculating machines, characterized essentially by the fact that it consists of a concavo-convex conductive laminar disk, endowed on its concave face with projections near the edge, regularly distributed, on which it rests on an annular conductor of a circuit printed, in the center of which is located another conductor that is also part of said circuit, electrically separated from the first, and that in the position of rest of the pulsator is slightly distanced from the laminar disk, which is located inside the an opening provided in an insulating plate, carrying as many openings as pushbuttons has the calculating machine, and adhered on the printed circuit board on one of its faces, while on the opposite side is attached a waterproof and flexible sheet that closes hermetically the openings, on which are arranged some keys in front of each opening, equipped with a central projection with respect to the laminar disk and resting on it, so that when pressing the key the projection deforms the disc that flattens, establishing connection with the central contact and recovering the initial position when the pressure on the key ceases.
