The Main Battery Switch is an essential component for every boat. It disconnects your engine and all your standard (non-24 hour) loads from your boat’s batteries and prevents battery drains while in storage.
Our master battery switches are high-current physical disconnects made with marine-grade materials, and capable of handling your full engine cranking current.
