Arrangement for illuminating a switch surface for a touch sensor switch
First Claim
1. An arrangement for illuminating at least one switch surface (3) provided on a transparent panel (1), said arrangement comprising at least one light source (9) and a touch sensor switch (5) arranged behind the at least one switch surface (3), wherein the at least one light source (9) is positioned and spaced from the at least one switch surface (3) so that the at least one light source (9) radiates light into the transparent panel (1) or into a light waveguide (15, 16, 17, 19, 20) arranged on the transparent panel (1), said light of the at least one light source (9) guided into the transparent panel or the optical waveguide is guided toward the at least one switch surface (3) and conducted into a region between the at least one switch surface (3) and a sensor element (7) of the touch sensor switch (5).

Abstract
The arrangement for illuminating at least one switch surface (3) provided on a transparent panel (1) has at least one light source (9) and a touch sensor switch (5) arranged behind the at least one switch surface (3). The illumination should not interfere with the switching function and a touch sensor switch (5) does not need its own light source (9). The light source (9) is spaced from the at least one switch surface (3) so that the at least one light source (9) radiates light into the transparent panel (1) or into an optical waveguide (15, 16, 17. 19. 20) arranged on the transparent panel (1). The light of the at least one light source (9) is guided into the transparent panel or the optical waveguide toward the at least one switch surface (3) and conducted into a region between the at least one switch surface (3) and a sensor element (7) of the touch sensor switch (5).
