 My temporary phone has an insane autocorrect feature.

Look for relays in a cylindrical case with wire legs.  I think West in g house used to make them.  Already silent,  though more expensive.   We used them for all audio and r.f. switching at BP.

Why can I not use relays to switch audio? What's wrong with relays?

BTW, I was thinking of acoustically dampening relays. EG use sound
proofing foam.
