RE: [TCML] PFC reflection back to current control.

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi Bart,

Yup, I agree. I used to have one on the front side of my variac for my 8"
coil with a red neon pilot light (in a double wide box and cover ), Even at
zero volts there was power output on my neon transformer that could bite.
(yes I prefer to hold the plug) I had to put some MOV's on it when the first
one fried, I guess from kick back.

I ALWAYS shut off the breaker or disconnected the power to adjust the tap.
The ganging idea is cool. Stacked switch boxes are cheap too.

And many thanks to Deano for his excellent explanation of PFC and pig power
variables!

Light switches work excellent for all kinds of gizmo's (and their low 
priced). I've built a few of these up to about 20 switches in a row for 
testing various sensor inputs for cmos logic circuits. They are robust 
and would certainly work well for PFC variation.

Take care,
Bart
