I would like to find a simple circuit for a TTL controlled analog
switch.  When the logic input is in one state, I'd like the switch to
pass a +/- 10v analog signal.  When the logic input is in the other
state, I'd like the analog output to be ground.

I'm sure this is simple, but a solution has so far eluded my mechanical
engineer's brain.  

Any help or pointers would be appreciated.
