Abstract:
1. An electrical switch with multiple switching channels comprises: a support frame; a panel which is mounted in a mobile manner relative to the frame and which comprises a face with which a pointing element is configured to come into contact; an element which determines a point of contact of the pointing element on the face of the panel, comprising a plurality of electrical switching elements, each of which is associated with a switching channel, which are configured to change state selectively, depending on a position of the point of contact, when the pointing element comes into contact with the face of the panel; a detection element which detects at least one control action which is configured to establish an associated switching channel when a pressing force with a value greater than or equal to a threshold value is exerted on the face of the panel by the pointing element, the switching channel being independent of the position of the point of contact with the face of the panel; and an intermediate plate that is arranged between the panel and the frame, and on which the panel acts in order to cause a change in state of the switching elements, wherein the intermediate plate is configured to cause the change in state of switching elements and is configured to act on the detection element under the at least one control action of the panel, and in that the intermediate plate can be at least in part deformed in order to actuate the detection element of the at least one control action after changing the state of the switching elements, wherein the detection element is arranged at a center of the panel and the switching elements are distributed around the detection element, and in that the intermediate plate comprises a central portion for actuating the detection element and comprises radial portions extending radially outwards from the central portion, wherein an outer radial end of each radial portion is configured to cause a change in state of the switching element which is associated with the radial portion, and wherein the central portion of the intermediate plate comprises a pusher made of an elastically deformable material, which is connected to inner ends of the radial portions.
