Overview

Battery master switch 2 pole provides off-on battery isolation for trailer, truck and heavy vehicle electrical systems.

The double-pole design disconnects both the battery and field circuit, so it supports safer service work and helps control battery drain during storage.

Features

• Double-pole, 2-position off-on battery master switch.
• Includes removable key for controlled battery isolation.
• Plated steel case suits heavy vehicle electrical service.
• Chrome-plated die-cast lever gives a clear manual switch action.
