Compact Battery Selector Switch
Fig. 8511 - Medium Duty
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 surface-mounted in numerous locations & positions. Also, 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 2 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. They facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged. 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.
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.
