The 4-position rotary dial lets the operator select Battery 1, Battery 2, Both, or OFF, so isolated banks can be run independently or combined to power all loads as needed. The switch is ignition protected, so it can be mounted in the engine room of gasoline powered boats as well as in dry electrical panel spaces.\u003c\/p\u003e\u003cp\u003eConstruction uses a durable plastic housing with a rotary knob that has a tactile texture, allowing the operator to confirm switch position by feel in low light or no-light conditions. The terminal studs are one-piece tin-plated copper, long enough to accept multiple cables while providing the torque needed for a secure, low-resistance connection. The switch offers multiple mounting options and can be installed on the surface of a panel or from the rear of a panel, with a 32 mm mounting hole. The housing carries an IP66 ingress protection rating for resistance to dust and heavy water spray, making it suitable for engine room and helm installations where moisture exposure is a concern.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea
