The 721 heavy-duty selector switch provides four operating settings: Off, Battery 1, Both, and Battery 2, allowing you to charge a selected battery or isolate current draw to a single battery. The switch can be recess-mounted in an 85mm hole or surface-mounted. Screw holes: 5 mm roundhead. A removable rear cover insulates the rear terminals against a short circuit, and removable side plates provide access to heavy-duty battery cables. Please note that this system will not protect electronics from harmful engine-starting spikes.
