Re: All Windings Off setting, Camtronics 5A boards

Hi Ray,

That's what I meant. The E-switch has a N/C contact that opens when
pushed. The opening switch opens the holding circuit to the relay.
What I haven't found yet is the connection information for the
contactor.

Or are you saying that the contactors don't work quite the same? I've
never had the luxury of a fancy "contactor", I've just wired holding
relays previously.
