IF you have an electronic keyer and you want to use

all the time, what circuit would you use to switch
between rigs.

Electronic keyer would go to the switch and switch
to multiple outputs.

Doesn't seem like it would take much more than the
switch but would you use diodes on the outputs,
capacitors on the grounds ??
Seems like the ideal application for optocouplers. Bias one for
positive keying and the other for negative keying (TS-520, TS-830,
etc.). Use as many as needed for multiple rig outputs. Isolation
between rigs and between the tigs and keyer.
