Hello Eric:

I've been using a simple setup since I first started playing with coils
that has worked very well for me.  I mounted a contactor (another name
for a heavy relay) and a 24 volt transformer in a metal box with a long
length of zip cord going to a hand held push button.  I put some small
R.F. chokes on the button leads and a couple of bypass caps to ground
to keep the high frequency stuff at bay.  The box has a regular three
pin power cord and a single grounded receptacle.

Pressing the button allows the 24 volts to close the contactor and apply
power to the T.C.  If I should happen to take a hit from the coil, I'll
drop the switch and the juice will be cut off instantly.  The transformer
I used to operate the contactor has a tapped primary which allows it to
be operated from either 120 or 240 volts.  When my coils get bigger and
require more power, I'll just rewire the primary and change the power in
and out connectors to 240 volt units.
