Thanks, gang. There goes another $75 in parts costs because I don't have to have a switch that can go spdt. A pushbutton "on-off" headphones will do just fine.
Back to the test bench ... But the best engineer story I've heard in a while ...
Doctor, lawyer, engineer were asked if they had their choice between a girlfriend and a wife, which one?
The lawyer said girlfriend ... a little more spicy, a little more unexpected...
The doctor said wife ... a little more stable, a little more reliable...
The engineer said both. When I'm missing the wife will think I'm with the girlfriend, the girlfriend will think I'm with the wife and I can get back to the lab and get some useful work done.
