Perko 8502DP Locking Battery Selector Switch, Red, 6 to 50 Volt Marine Systems
Perko 8502DP Locking Battery Selector Switch, Red, 6 to 50 Volt Marine Systems
The Perko 8502DP is a locking battery selector switch designed for boats running two or more batteries on single or dual engine systems. It lets you choose which battery bank powers starting and charging, or combine both batteries in parallel operation, and the built-in key lock prevents unauthorized or accidental switching once a position is set. The switch body is molded polycarbonate with brass terminals for corrosion resistance, and it is ignition protected for safe use in gasoline engine spaces.
Electrically, the 8502DP is rated for 6 to 50 Volt marine electrical systems and handles up to 250 Amps continuous or 360 Amps intermittent load, covering the demands of most recreational and light commercial boat electrical systems. Terminals accept a 3/8 inch stud connection. The switch measures 5-1/4 inches in diameter with a 2-5/8 inch mounting depth, sized for standard helm or engine bay panel mounting. For dual engine boats, Perko recommends installing two switches, one per engine, to manage each battery bank independently. The red finish provides clear visual identification at the helm or in the engine compartment.
