following the contour of the button until it is at the dimension of the diameter of the button shaft 39 which may vary depending on the button the surface 37 of the recess 24 then extends downward away from the rim 20 thereby forming the lip 28 that fits snug around the shaft 39 of the button 35 when the button is inserted through aperture 26 the lip 28 although not required provides additional support to the cover 10 and thus it is preferred to include a lip that extends a significant portion down the shaft of the button furthermore the lip 28 may also include one or more optional holes 40 wherein a screw or pin can be inserted to secure the button in place one skilled in the art should understand that the rim 20 can be designed to fit the contour of the users hand thereby providing an improved gripping surface as such the rim 20 may take a number of different shapes and sizes depending on the desired feel the underside 41 of the surface 37 of the recess 24 includes a number of ridges 30 that extend perpendicular to the surface 45 of the rim 20 these ridges 30 are designed to be elastic and thereby adsorb the energy that causes the stinging sensation in the operator 39 s fingers preferably the ridges 30 have an elasticity between approximately 40 and 75 durometer shore a and preferably between approximately 50 and 55 durometer shore a furthermore a set of approximately 12 18 ridges 30.
