A powerful new generation battery switch with outstanding performance and features for both the installer and end user. Three mounting options: surface, rear panel, and front panel mounting, plus optimized cable access makes installation a breeze. Pro Installer switches set the new benchmark with outstanding ergonomics, intuitive look/feel, and are engineered from the finest materials to withstand the harsh marine environment. Same industry standard mounting with On/Off operation. Used where positive and negative supplies must be isolated at the same time. SAFETY NOTE: BEP does not recommend this for switching house and start battery systems at the same time, for safety reasons. You may need to isolate your engine battery in an emergency, but not your house battery which typically powers the communications. For this application please use the new Dual Bank Control Switch (772-DBC) or one of BEPs battery switch clusters.
