Method for the optical marking of a touch contact switch and touch contact switch
First Claim
Patent Images
1. A method for optically marking a touch contact switch under a cover by using a plurality of illumination sources, wherein said touch contact switch has defined actuation states comprising “
- not actuated”
, “
incorrectly actuated” and
“
correctly actuated”
,wherein at least a subset of said plurality of illumination sources are activated if the touch contact switch is in said “
correctly actuated”
state,wherein said subset of said plurality of illumination sources are deactivated if the touch contact switch transition is in said “
not actuated”
state and wherein further said subset of said plurality of illumination sources are deactivated with the removal of a user'"'"'s function contacting a partial contact surface of said cover, andwherein at least said subset of said plurality of illumination sources change their illumination state when the touch contact switch is in said “
incorrectly actuated”
state.

Abstract
An elongate contact switch is disclosed having several partial contact areas and associated illumination means for indicating the actuation mode and also the actuation point to an operator, in order to increase operational effectiveness. The illumination means can be directly associated with individual partial contact areas or can indicate the progress of movements for operating the contact switch by applying a finger and pulling the same along a contact area. Moreover, malfunctions can be indicated to the operator.

10. A touch contact switch comprising:
-
a plurality of contact surfaces on a surface cover configured to detect a touch of a user'"'"'s finger at a point on one of said plurality of contact surfaces, wherein said touch contact switch has defined actuation states comprising “
not actuated”
, “
incorrectly actuated,” and
“
correctly actuated”
; anda plurality of illumination sources comprising a plurality of subsets of illumination sources, wherein at least one or more subsets of said illumination sources are configured to change activation state as a function of a transition of said touch contact switch from a first actuation state to a second actuation state. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A touch contact switch comprising:
-
a cover comprising indicia for indicating a boundary thereby defining an area within said boundary, wherein said cover can be touched by a user'"'"'s finger; a plurality of contact surfaces aligned in an adjacent manner below said cover configured to detect a touch of said user'"'"'s finger at a touch location point on said cover, wherein said touch contact switch is configured to evaluate said touch location point as “
not actuated”
, “
incorrectly actuated”
, and “
correctly actuated”
;wherein if said touch location point is within said area within said boundary, said touch contact switch evaluates said touch location point as “
not actuated”
or “
correctly actuated”
, andwherein if said touch location point is outside said area, said touch contact switch evaluates said location point as “
incorrectly actuated”
; anda plurality of illumination sources comprising a plurality of subsets of illumination sources, wherein each one of the plurality of subsets of illumination sources are each respectively associated with a one of the plurality of contact surfaces, wherein at least one or more subsets of illumination sources are configured to change activation state as a function of the evaluation of said location points as “
not actuated”
, “
incorrectly actuated”
, and “
correctly actuated”
.
