A power window control includes four levers, one on each control switch. Two of the levers are long and the other two are shorter. The long levers are provided on the two switches further away from the user (which control the front and rear left side windows). The short levers are attached to the two switches closer to the user (which control the front and rear right side windows). The base of each lever can be attached to the corresponding switch through a heavy-duty double-sided tape, where for flat switches, the lever is attached directly to the switch surface and for contoured switches, an adapter can be provided between the base of the lever and the surface of the power window switch. ## Claims ### Claim 1 A switch lever system for a vehicle power window switch assembly, said switch lever system comprising: a first lever element having a first vertical tab; a second lever element having a second vertical tab, wherein a height of said first vertical tab is greater than a height of said second vertical tab; a first adapter having a contoured lower surface and a flat upper surface configured to be removable attached to a flat lower surface of said first lever element; and a second adapter having a contoured lower surface and a flat upper surface configured to be removable attached to a flat lower surface of said second lever element. ### Claim 2 (depends on 1) The switch lever system of claim 1, wherein the flat lower surface of said first and second lever elements comprise adhesion elements. ### Claim 3 (depends on 1) The switch lever system of claim 1, wherein the contoured lower surface of said first and second adapters comprise adhesion elements. ### Claim 4 (depends on 1) The switch lever system of claim 1, wherein the flat upper surface of said first and second adapters comprise adhesion elements. ### Claim 5 A vehicle power window switch assembly comprising: a first window switch including a first lever element with a first vertical tab; and a second window switch including a second lever element with a second vertical tab having a height smaller than a height of said first vertical tab, wherein said first window switch and said second window switch are provided on a power window switch assembly so that said first window switch is positioned on a side of said second window switch closer to a vehicle door panel, and said first lever element comprises a base having a contoured lower surface removably attached to a mating contoured upper surface of a cap of said first window switch and said second lever element comprises a base having a contoured lower surface removably attached to a mating contoured upper surface of a cap of said second window switch. ### Claim 6 (depends on 5) The vehicle power window switch assembly of claim 5, wherein the contoured lower surface of said first and second lever elements comprise adhesion elements. ### Claim 7 A vehicle power window switch assembly comprising: a first window switch including a first lever element with a first vertical tab; a second window switch including a second lever element with a second vertical tab having a height smaller than a height of said first vertical tab, wherein said first window switch and said second window switch are provided on a power window switch assembly so that said first window switch is positioned on a side of said second window switch closer to a vehicle door panel; a first adapter having a flat upper surface configured to be removably attached to a flat lower surface of a base of said first lever element and a contoured lower surface configured to be removably attached to a mating contoured upper surface of a cap of said first window switch; and a second adapter having a flat upper surface configured to be removably attached to a flat lower surface of a base of said second lever element and a contoured lower surface configured to be removably attached to a mating contoured upper surface of a cap of said second window switch. ### Claim 8 (depends on 7) The vehicle power window switch assembly of claim 7, wherein the base of the lower surface of said first and second lever elements comprise adhesion elements. ### Claim 9 (depends on 7) The vehicle power window switch assembly of claim 7, wherein the contoured lower surface of said first and second adapters comprise adhesion elements. ### Claim 10 (depends on 7) The vehicle power window switch assembly of claim 7, wherein the flat upper surface of said first and second adapters comprise adhesion elements. ### Claim 11 A retrofit kit for adapting a vehicle power window switch assembly, said kit comprising: a pair of first lever elements, each having a first horizontal base and a first vertical tab; a pair of second lever elements, each having a second horizontal base and a second vertical tab, wherein a height of said first vertical tab is greater than a height of said second vertical tab; a first pair of adapters, each having a contoured lower surface and a flat upper surface configured to be removable attached to a flat lower surface of a respective first horizontal base; and a second pair adapters, each having a contoured lower surface and a flat upper surface configured to be removable attached to a flat lower surface of a respective second horizontal base. ### Claim 12 (depends on 11) The retrofit kit of claim 11, wherein said first pair of adapters and said second pair of adapters, each includes adhesion elements on said contoured lower surfaces and said flat upper surfaces.
