Basically, it's four three way switches. You seen single and double switches, these are just four combined.
You could use two six ways, but you'd get all connections changed at the same time if you use a 12 way.
wouldn't that only give 12v power to the 3 way switch?
Yes
SixtyFourChevy, you are right. At the time I made this, it was all I needed and worked fine with the dump I had.
NOTES to Newbies: 24 volts at the switch is the way to go, even when the parts are made for 12 volts. But 12 volts does work if there are no extremes.
