SW202 Contactor Wiring Diagram *
(Size: 450.9 KB)
Change-over contactors are multiple contactors bound together that allow the user to change the polarity of the voltage going to the motor thus reversing direction. It works exactly the same as the manual F/R switch, except that it uses coil drive contactors. -Alltrax
