How much power does a 120v 15A lighted switch use anyway?

Do you know how much power a lighted switch uses?
These have an NE-2 neon bulb which draws about 0.6mA, so at 120V it's
around 0.07 watts. So 1000 lighted switches would be a little less than
* a 75 watt light bulb.
* *My experience with a lighted switch is that its neon lamp is either
an A1C ("mini-NE-2H") or a C2A (NE-2H). *Those get more like 2 mA.
I was going by the NE-2, which actually is about 0.03W at 120V, but an
NE-2H is about 0.2W, and an A1C is about 0.14W. So if the light switch
was never turned on, and it was an NE-2H, it would be about 1.7KWH per
year, so you're right, about 2KW a year if it's an NE-2H.

Which is negligible...not to worry about...not to budget for...not to
have ulcers over. In other words...forget it.
