View Full Description
Marine electrical master battery switch. Ideal for RIB's, speed boats, jet-ski's, power-boats and sailing boats. Isolate your marine battery system, cutting off all possibility of battery-induced galvanic corrosion to help prolong the life of propellers, prop-shafts and other metallic fittings which can otherwise suffer from the effects of marine electrolysis if micro-currents are allowed to flow. Including a mater-switch in your marine battery system also give peace of mind, knowing that if there is an electrical malfunction you can isolate everything while you investigate the source of the problem. This unit comes with a removable key. Also included is a waterproof cover so that when you leave the boat (and remove the key) you can cover the switch the a waterproof rubber cap.
