Perko 250 Amp Battery Selector Switch with Alternator Field Disconnect

Designed for surface mounting, the Perko Battery Selector Switch has a bright red polycarbonate housing with a large easy-to-turn black knob.

The Perko Battery Selector Switch has a number of functions – they allow 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.

The Alternator Field Disconnect feature offers protection for Non-Unitized Alternators, should the switch accidentally be turned to the "OFF" position with the engine running.
