Abstract
Switch assembly for changing the direction of current from a power source to an appliance comprising—at least four wirings, two of the wirings are connectable with the power source and the remaining wirings are connectable with the appliance,—all wirings are fixed on the surface of a substrate and none of the wirings are directly connected to each other,—a first button comprising a first conductive pattern on one surface of said button,—a second button comprising a second conductive pattern on one surface of said button,—the surfaces of the buttons on which the conductive patterns are arranged face the surface of said substrate where the wirings are arranged,—the buttons are fixed on the substrate—the conductive patterns on the buttons and said wirings on the surface of the substrate are arranged in such a manner and said buttons are placed on said substrate in such manner, that (i) said conductive patterns on the buttons are not in contact with said wirings in an unpressed state of the buttons, (ii) one button connects by means of the conductive pattern in a pressed state simultaneously the first wiring of the two wirings with one wiring of the remaining wirings and the second wiring of the two wirings with another wiring of the remaining wirings to enable a first current path through the switch assembly, and (iii) the other button connects by means of the conductive pattern in a pressed state the first wiring of the two wirings with one wiring of the remaining wirings and the second wiring of the two wirings with another wiring of the remaining wirings to enable a second current path through the switch assembly being different to the first current path, wherein further the conductive patterns comprise a composition (CO) comprising a polymer and a conductive material dispersed in said polymer and/or a conjugated polymer.
