 Perko Compact 1-2-All Battery Switch

The Perko 8511 Battery Selector Switch is a compact and durable battery switch that has a bright red polycarbonate housing with a large easy-to-turn black knob. The Perko Compact Battery Selector Switch has a number of functions – its allows for a quick and easy way to shut down the entire electrical system in an emergency; this device also permits battery selection (of two or more batteries) for specific purposes, including starting engines, running accessories or even recharging. This device can also facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged. 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.

The Perko Compact Battery Switch has a small footprint for easy installation. This switch can be mounted in numerous locations including the engine rooms of gasoline powered boats. 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.
