Cole Hersee M750BP Dual Battery Switch

The Cole Hersee M750BP is a marine-grade dual battery switch designed to manage power distribution between two battery banks. This ignition-protected switch allows you to control which battery or batteries supply power to your electrical system, while also providing a complete shutoff capability.

Key Features:

• Four-position rotary switch: OFF, Battery 1 only, Battery 2 only, or BOTH batteries combined
• Ignition protected construction meets USCG and ABYC safety standards
• Durable plastic case with molded insulator for reliable corrosion resistance
• Heavy-duty contacts for continuous duty rating
• Prevents accidental battery drain when equipment is not in use
• Allows parallel battery operation for heavy electrical loads

This battery selector switch is ideal for marine, RV, and commercial vehicle applications where dual battery management is required. The OFF position provides a master disconnect for safety during storage or maintenance. The BOTH position combines batteries for engine starting or high-demand situations, while individual battery positions allow you to preserve one battery as a backup or isolate a battery for charging.
