How would you repair those very thin copper contacts?

[HobGoblyn]

Have a cordless drill, one of the contacts on the switch has broken as per the attached photo  (and you can see the circuit board where the contact touches).

Also included a bad drawing showing how it fits in to the plastic switch.

Is it possible to repair these things (make a new one out of something) or am I wasting my time trying?

Thanks

Its not copper, because it needs to be springy.  Its probably made from spring temper phosphor bronze shim stock.  Reproducing it would be really difficult, especially forming the contact tips so they don't scratch the contacts on the PCB.  You might be able to patch it up by forming a new tab of springy brass of comparable thickness, and soldering it overlapped onto the base of the U, by tinning both surfaces and sweating them together.

I thought it probably wasn't worth it, especially as I've since  found the complete switch for £6 from China on ebay.

Just don't like things to beat me

it might be beryllium copper, BeCu. known to the state of California...by the way, cutting wood is known to the state of California...

I've been able to glue it down onto aluminum and cut it with a very small end mill running in an oil bath.  With very small nippers you might get close enough by hand.  Given your goal is to repair, though, get the switch...ha.
