Method of forming a component for a control panel
View Patent ↗A control panel assembly having a plurality of buttons located in a bezel and supported by a switch mat. A bezel and/or button is formed using a vacuum forming technique and has a transparent inner surface layer and a middle translucent color layer and an opaque outer surface layer. A portion of the opaque outer surface layer is removed to define a desired indicia on an outer surface of the bezel or button. In addition, the bezel or button can be backlit to allow visibility in low light conditions. A method of making a control panel component, such as a bezel or button, is also disclosed.
1. A method of forming a component for a control panel, the component being vacuum formed and having a shaped main body, the main body including first and second layers and a third layer applied to said second layer wherein said first layer is generally transparent, said second layer is generally translucent, and said third layer is generally opaque; the method comprising the steps of:
coextruding the first layer and the second layer of material;
vacuum forming coextruded first and second layers into a predetermined shape; and
applying the third layer to the second layer.
2. The method of claim 1 , wherein the step of applying includes one of thermally bonding, spraying, or printing.
3. The method of claim 1 , wherein the vacuum forming step is preformed after the step of applying said third layer.
4. The method of claim 1 , wherein the vacuum forming step includes vacuum forming a bezel.
5. The method of claim 1 , wherein the vacuum forming step includes vacuum forming a button.
6. The method of claim 1 , further comprising providing indicia on said component.
7. A method of forming a component for a control panel, the component including a main body including first and second layers and a third layer applied to said second layer; and a third layer applied to the second layer, wherein said first layer is generally transparent, said second layer is generally translucent, and said third layer is generally opaque, the method comprising the steps of:
coextruding the first layer and the second layer of material;
vacuum forming said coextruded first and second layers into a predetermined shape;
applying the third layer of material to said second layer; and
selectively removing a portion of said third layer of material to expose a portion of said second layer for forming indicia on said component.
8. The method of claim 7 , wherein said step of applying includes one of thermally bonding, spraying, or printing.
