I don't know what the cost of the handle unit is off hand, a quick call to Bobcat could tell you. As for the switch, it's not so much the switch as it is the circuit. Although the switch is nothing more than a typical potentiometer switch, I don't know what its ohm values are and Bobcat doesn't tell and it works via three wires, a reference voltage from the main controller, a feedback signal to the main controller, and a ground signal to the main controller, all three of these wires are connected to the main controller and it monitors the signal to and from the switch, even if you haven't activated the auxiliary circuit. If there's something not right about the voltage/resistance values on those three wires the main controller will sound the alarm and prevent the auxiliary circuit from operating. Again, Bobcat doesn't tell us what all these values are. Now it's possible a Bobcat tech could plug his laptop into the test port and get more accurate information, pinpoint the problem, but again, that's proprietary Bobcat tech stuff, but it's an option you may consider inquiring about, be worth the money to diagnose and pinpoint the problem if it's possible.
