MDS10 Switch Silver

The MDS10 Switch Silver is a heavy-duty battery disconnect rotary switch engineered for marine electrical systems, racing applications, and recreational boating where reliable power isolation is critical. For anglers, boaters, and anyone operating on extended water time, this panel-mount switch provides instant manual control over your 12-volt battery bank—essential insurance against electrical fires, parasitic drain, and accidental battery depletion when your vessel sits idle. QuickCar Racing Products designed this switch to handle the demanding electrical demands of modern marine installations and dual-battery setups without compromise.

Rated for 250 amps continuous at 12 volts, the MDS10 Switch Silver features a robust aluminum construction with a polished silver finish that resists corrosion in salt and freshwater environments. The rotary design ensures smooth, positive engagement between the ON and OFF positions—no ambiguity about electrical state, which matters when you're troubleshooting systems or securing your boat before winter storage. Its compact footprint (5.35 x 5.3 x 5.7 inches) and panel-mount configuration allow flexible installation in tight engine compartments, console dash spaces, or remote battery boxes, while the die-cast aluminum housing maintains structural integrity despite vibration, thermal cycling, and humidity inherent to marine service.

Boaters running GPS, VHF radio, bilge pumps, and auxiliary lighting benefit most from this switch's ability to isolate the main battery circuit instantly, reducing parasitic draw by 100% when the boat is unattended. Installation is straightforward: mount to any vertical or angled panel, connect your positive battery cable to one lug and main system bus to the other, and operate via the external rotary handle. Weighing just 1.09 lbs and compatible with standard 12-volt automotive and marine electrical systems up to 250 amps, the MDS10 Switch Silver is an insurance policy every serious angler and boater should carry.
