Abstract: An electric switch of mechanical structure and functioning, and with electric contacts by means of membranes, suitable for optionally arranging seven different control signals by means of other such contact positions selectively induced by a single button means, four of these positions are differentiated when a slight rolling movement is carried out on said button means in any of four opposite directions and 90° equidistant from each other, a fifth contact position in its clockwise axial rotation, the sixth position by means of its counter-clockwise rotation, and a last contact position by means of a linear pulsating movement.

Abstract: The invention relates to a communication circuit which is used to connect, via a data bus, window-opening and -closing switches to the control circuits for the respective motors thereof and to the central vehicle controller. Said system can be used to control the sun roof and the passenger window from the driver's seat. The aforementioned switches can be: rotated, in order manually to adjust the degree that the window is opened; and moved, in order to activate the automatic and full opening or closing of the window.
