Review on Top Post Battery Disconnect Switch For Car, Truck, Boat, RV - Cllena Auto Parts For Ultimate Power Management by Frank Chinchilla

Update: Used the switch on my lawn tractor battery. Made a bracket to accommodate the different battery terminal. So the switch hangs off the terminal. Since the voltage disconnect at the switch is the metal flange on the screw knob, and the switch hangs, the screw knob has to completely be removed. The fix is easy! Just tie wrap the two piece switch on each side of the screw knob to keep the switch together. Now just turning the screw knob couple turns disconnects voltage.
