Well, the CD4514 or CD4515 might serve your needs, but they are not
switches; they are decoders which output normally high or low logic
signals. They can be used to control switches, etc.

Used way back when by Thomas Henry in his SuperSeque in Polyphony
mag. He used the CD4516 as a counter.

These parts are in production:
