I'm fairly sure that I asked this question before, but it has been a habit
of never put off till
tomorrow what you can put off till the day after.

I chose phosphor bronze because in the days of making one's own electronic
organs, phosphor bronze was suggested as a suitable keying matreial for the
keyboards.







If a question's worth asking, Gareth...







I have not made lots of keys, but when I do I use contacts from old
relays. I still have some relays I bought as WWII surplus when I was in
my teens, back in the 1950's. They have strange coil parameters, weird
mounting arrangements, etc., but nice little silver contacts.
