Dan - It seems hard to believe that the switch is your glider is so
"weak" that it cannot handle the amperage of your instruments. When
you say "delicate" could the switch be damaged? If it is intermittent
it could have built up some oxidation or carbon which is acting like a
resistor limiting the voltage to your devices. I've never seen this
myself but it is possible. Of course replacing the switch with
something NOT from Radio Shack is the next approach. Look for name
brands like Switchcraft, Alco or C&K. Maybe I am stating the obvious.
