Abstract

Abstract A functional and aesthetic switch plate providing an extension to a wall toggle switch. The switch plate not only provides a useful mechanical extension to a toggle switch, but has a sliding toggle switch lever extension member which covers its own wear marks and is of sturdy unibody construction. The sliding toggle switch lever extension member is connected to the reflecting rear surface of the base plate by sliding contact members positioned beyond the reflecting base edges to prevent chipping of the reflecting base edges.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 325 words
A reflective switch plate assembly, comprising: a clear base plate with a through opening and a front surface and a rear surface; a reflective material connected to said rear surface of said base plate; a non-removable toggle switch lever extension means non-removably fixed in said opening for sliding reciprocal movement within said opening, said extension means having a front portion means with a rear side mid portion and a rear portion with a front side, said extension means for fitting over a toggle switch lever for controlling the position of the toggle switch lever by sliding said front portion means of said extension means back and forth over the surface of said base plate within said opening; said extension means including two upper cams on said rear side of said front portion means for sliding contact with said front surface of said base plate of said switch plate assembly, said two cams causing wear marks on said front surface; said front portion means for covering said wear marks in all positions and being larger in length than said two upper cams so that said wear marks left on said front surface of said base plate caused by friction of said two upper cams are covered; said extension means having two lower cam means positioned on said front side of said rear portion, said two lower cam means positioned for movement against said reflective material on said surface of said base plate, said two lower cam means each having a width; said two lower cam means positioned to make contact with the said reflective material spaced away from the sides of said opening a distance no greater than said width, said two lower cam means spaced from said opening and having said width for preventing chipping of said reflective material along said through opening for preventing visible marks; said mid portion extends through said through opening and connecting said front portion means and said rear portion.
