<p>Switching device for the programmer of an automatic washing machine comprising a cam-program unit, comprising at least one insulating base on one face of which are printed a series of concentric circular conductive tracks (11e), and a series of conductive sliding contacts (15). The insulating base (11) is fixed, the sliding contacts (15) are joined together and rotated with the cam unit, all the tracks are continuous over 360 DEG and radially distanced from one another, and conductive means are provided which are attached to respective terminals and are intended to be electrically joined in pairs, as well as means of interrupting the electrical connection between these conductive means when the cam unit rotates. <IMAGE></p> |
