Agreed.  I have replaced more than one power switch on DEC terminals
from "over-frobbing".  The VT220/VT240 switch had a standard
footprint, so I was able to get a functional replacement at Radio
Shack for a few dollars.  The VT100-family can take a standard
ball-bat type toggle with brass fast-on tabs.  I'm not sure about the
switch type on the VT420, but definitely check that power is getting
through it, especially if it feels "soft" when flipping it.
