Spare Switches?

[Super]

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.

Not a bad idea Super, I'll have to see what I can find, these days we don't seem to have hobby/model stores as such anymore, they've sadly pretty much all gone

If you have no Hobby Stores in your area I am sure you could pick some up from an Ebay seller in your country or maybe Amazon.

Or Craig's list. Make sure you meet the buyer in a public place

Yeah, I'll find some somewhere, just need a bit of time to go looking this weekend
