Discuss Do illuminated switches pass current to the load side when off? in the DIY Electrical Advice area at ElectriciansForums.net
A more comprehensive reply to the OP would be that if the illuminated switch were double pole, switching both live and neutral, then the illuminating neon/led would be across the supply, and not powered through the load.
Where the switch is single pole, traditional for a light switch, and merely interrupts the live supply, the illumination is usually wired across the switch terminals, and draws current through the load when the switch is off.
This is just a simple signle pole switch. When using a filament bulb the light is off, but the LED-type bulb is dim. Since posting this question I took a second switch (I bought two) and just carefully wired it up to AC and sure enough, when it is "OFF" I still see about 25VAC. That really surprises me... assuming that means its supposed to be like that (figuring I didn't buy 2 faulty switches), then what if I had a motor or something other than a simple light bulb on that circuit...
