Acrylic was around in 1970, but yes, it could be a transparent polystyrene. Someone turned up about seven of these things on ebay a couple of years ago. They were the complete switch. It's the only reason I have a little red cap now. I think they went for between $20 and $25 each. If you could keep the cost low enough, I'm sure you could sell all you wished to produce.

I am tempted to make a mold of the red plastic part and cast one under

maybe acrylic (possibly too early for that material, can't remember). I've
been making missing keys and other parts for my weird little collections
in this way so why not a switch top?
