blackie is right you can get an auxiliary micro switch to fit on top of the albright contactor but it is a pig to fit, that is if you don't brake the contactor top trying to get the hole through it for the plunger, if you fit a small 5 - 10 amp relay accros the reverse coil it will operate when the reverse contactor closes and because it takes about 1 amp to operate the the contactor coil and a 5 -10 amp relay draws only about 100 mA the controller will not even know it there and it will not damage the driver circuit.
