Perko 8511 Series compact battery selector switches use the same traditional Perko bolt pattern as the 8501 Series but with a smaller footprint. This makes for easy installation. These switches can be mounted in numerous locations and positions. And as ignition protected switches, they can be installed in the engine rooms of gasoline powered boats. In addition to doing everything a battery disconnect switch does, battery selector switches permit battery selection (of two or more batteries) for specific purposes including starting engines, running accessories or even recharging. They allow for the use of one or more batteries in systems with one or more engines and facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged. Perko battery switches are designed for surface mounting. Standard duty switches have bright red polycarbonate reinforced housings for safety with large easy-to-turn black knobs. Selector switches are designed with a make before break feature. This allows switching between the 1, the ALL and the 2 positions while the engine is running. Versions of the 8511 Series switches offer additional features such as alternator disconnect and key lock security. Four removable skirt panels allow for easy cable connection from different directions. High conductivity studs are long enough to handle more than 1 cable and strong enough for torque needed for secure connections.

Junk. Do not buy this switch. First of all it this is what came in my boat when I bought it. In less than a year it failed. I bought the identical switch and it was bad out of the box.

Installed in really old boat with some phantom loads while in storage. This switch helps in three ways. 1) cuts off all phantom loads, preserving the charge. 2) Allows a new solar charger to maintain the battery without any boat devices in the circuit. 3) I can now install a house / deep-cycle battery as #2 and run battery #1 or #2 or both, as needed.

Works fine, easy to install, looks quality built. Only knock on it not being a 5 star is sometimes the switch doesnt fully rotate between selections and can get stuck halfway so you have to be careful that it is pointing directly in the middle of each selection before moving

Added a second battery to my pontoon boat. This switch filled the need very well. Very high quality. I installed it under the sun deck so it is out of the weather. I liked the options of taking the wires out any of four directions. Very positive detents for each position. Highly recommend.
