Reply to "Limit Switches"

I don't use any DPDT switch.  At the bottom of the schematic are 2 dots labeled track motor.  These are feeds from the controller, which simply activate a relay.  When a limit switch is activated, that button no longer has any effect---it can no longer pull in its relay.  The 2 SPDT relays are wired with the centers to the motor poles, NC's both to negative; NO's both to positive.
