You can also buy a sheet of white styrene in the appropriate thickness from a Hobby Shop, use a good switch to trace the missing piece and Super Glue it to the switch in a pinch. Plus you will have a lot left over for other type repairs or modifications. I have several sheets in various thicknesses and widths around in case I get an idea.
