Re: <ALL> Power window switches

[Dog-n-Hog <woody@xxxxxxxxxxx>]

Insert a resistor inline (in series) with the +12V supply to limit the current to
approximately 20 milliamps (R = E/I = 12V/20mA = 600 ohms).  Build
a test circuit first to make sure it works (a few LEDs already have a limiting
resistor built in).
