A cover for a vehicle parking brake control valve button including an elastomeric body and a plurality of elastic ridges. The body of the cover includes a rim and a recess designed to fit the contour of the control valve button. The ridges are designed to provide enough rigidity to support pressure applied thereto, and enough elasticity to absorb energy created by the actuation of the button. The absorption of the energy dampens the stinging sensation typically felt by the operator when actuating the parking brakes.

The invention claimed is: 1. A control valve button assembly for a vehicle comprising: a button having a button top attached to a button shaft; a cover connected to the button such that the cover moves with the button when the button is actuated, the cover including a rim defining a first aperture, a lip defining a second aperture, and an inner surface forming a recess between the first aperture and the second aperture, wherein the cover receives the button assembly within the recess such that the inner surface follows the outer contour of the button top and the button shaft and wherein the shaft extends out of the cover away from button top, and wherein the rim is larger than the lip; and a plurality of elastic ridges located on an outside surface of said cover for dampening energy created by the actuation of the button; the ridges extending axially along the outer surface from a position proximate the lip to the outer surface on the underside of the recess. 2. The control valve button assembly of claim 1 wherein the elasticity of the ridges is between about 40 and about 75 durometer Shore A. 3. The control valve button assembly of claim 1 wherein the elasticity of the ridges is between about 50 and about 55 durometer Shore A. 4. The control valve button assembly of claim 1 wherein the number of ridges included on the cover is between 12 and 18. 5. The control valve button assembly of claim 1 wherein the first aperture is generally square or diamond shaped. 6. The control valve button assembly of claim 1 wherein the first aperture and the recess mate with the contour of the button when the cover is assembled to the button. 7. The control valve button assembly of claim 1 wherein the rim is configured to fit the contour of a user's hand. 8. The control valve button assembly of claim 1 wherein the lip fits snug around the shaft. 9. The control valve button assembly of claim 1 wherein the plurality of elastic ridges and the cover are formed as a single piece. 10. The control valve button assembly of claim 1 wherein the cover is elastic. 11. The control valve button assembly of claim 1 wherein the rim has a top surface that is about flush with the button top when said button is fully inserted into the first aperture. 12. The control valve button assembly of claim 1 wherein the ridges extend radially perpendicular to the outer surface. 13. The control valve button assembly of claim 4 wherein the plurality of ridges are generally evenly spaced around the circumference of the cover.
