Perko 8511DP Compact Battery Selector Switch, On/Off, Ignition Protected

The Perko 8511DP is a compact on/off battery selector switch designed for boats where mounting space is limited. It uses the same bolt pattern as Perko's larger 8501 Series switches but with a smaller footprint, so it drops into the same mounting locations while taking up roughly a third less space. The rotary knob offers a smooth, easy-to-identify 90 degree turn between positions, making it simple to confirm at a glance whether the switch is on or off.

Because the 8511DP is an ignition protected switch, it can be installed in the engine room of a gasoline powered boat. Four removable skirt panels around the base allow cables to be routed in from different directions, and the high conductivity studs are long enough to accept more than one cable while remaining strong enough to handle the torque needed for a secure connection. The switch body is molded from red polycarbonate for durability and visibility, with brass contacts and a normally closed contact configuration rated for 50 Amps at 50 Volts. It uses clamp-style connectors with blade terminals and mounts to the surface via the standard Perko pattern.
