just a comment - a coil rated 220 VAC will work fine if you build a
simple
bridge rectifier and give it 110 DC - add a capacitor (filter) of 20 to
100
microfarads to keep the coil from buzzing and to give it a bit more
voltage.
snip -----
. Be aware that most of
the contactors out there are using 220 volt relay coils. If that is
all you can find (and you need a 110 type), then get a 110 to 220
volt transformer to power the coil. The contacts can be used for
either 110 or 220.
