 Harold,
"You could end up with 100 volts on the sleeve making it pretty easy to get a
shock. "
That is a very good point. Thanks for bringing that up.

 I really don't like the use of tip/sleeve connectors for this purpose. You
could end up with 100 volts on the sleeve making it pretty easy to get a
shock. I built my own patch boxes using 1/4 inch TRS jacks with shorting
switches. When nothing is plugged in, the tip and ring are shorted
together. https://w6iwi.org/rtty/20210125_164819.jpg
