Perko 9603DP Battery Disconnect Switch With Alternator Protection - Marine Grade

Boat owners, this Perko battery disconnect switch is one of those simple upgrades that can save you from major headaches down the line.

The 9603DP model includes alternator field disconnect - which is fancy talk for protecting your alternator if you accidentally turn the switch off while the engine's running.

We've all made that mistake, right?

This medium-duty switch handles 250 amps continuous and can spike to 360 amps for short bursts when you really need it.

The bright red polycarbonate housing makes it easy to spot, and those brass terminals provide solid conductivity that won't corrode in marine environments.

Mounting is straightforward with the traditional Perko bolt pattern that fits most standard installations.

As ignition protected, it's safe for gasoline engine rooms - no worrying about sparks where they shouldn't be.

The large black knob gives you positive control even with wet hands.

Use it to prevent battery drain during storage, isolate systems for maintenance, or as an emergency shutoff.

The terminals are long enough to handle multiple cables if needed.

This is one of those classic Perko switches that boaters have trusted for years because it just works reliably season after season.

Whether you're dealing with electrical issues or just want that extra safety measure, this switch gives you complete control over your boat's power system.

No more coming back to dead batteries after a few weeks off the water!
