  • Patent number: 4472609
    Abstract: A multiple flat-type switch consisting of three foils of insulating material placed on top of each other and bonded to one another. The center foil is provided with holes and the two outer foils are provided on their insides with contact surfaces which come into contact with one another when a pressure is exerted upon the foil arrangement. For the purpose of achieving a switch having a large overtravel (overlift) the contact surfaces are arranged in one row along the edge of the foil arrangement, while the leads extend almost vertically in relation to the edge of the foil. The foil arrangement is slotted from the edge within the area of the contact surfaces, and arranged on a foam-plastic base. For preventing the metallizations from being damaged, metal-free regions are provided for at the points of pressure attack, and the contact surfaces of the upper foil are connected in a spiral-shaped manner to their respective terminals within the area of the holes of the center foil.

  • Patent number: 4447686
    Abstract: In a pushbutton switch or pushbutton-actuated slide switch having a detent mechanism designed to have the shape of a heart cam, an individual latching and a mutual unlatching is made possible in that, according to the invention, the heart cam is provided with a further, center curved path for the unlatching (disengaging) purpose. Within this area of the position of the detent pin, the latching is accomplished by a cross slide which, during the off-switching process, can be pressed via a limit stop and by the detent pin into the unlatching (disengaging) position.
