Unfortunately, the function has not been tested yet.
The visual appearance and feel are great.

Robust with 3x M10 connections
Super robust, the switch is larger than conventional switches. I needed the 3x M10 connectors to cleanly integrate my Buck-Boost into the electrical system of my truck. The extra size doesn't bother me. I won't utilize the 600A either.-)

Technical question

Is it possible to block the "1&2" position so that no one can connect the 2 batteries together by mistake?

Answer from SVB customer service

Hello Giannis, that is not possible. It would be better to use a battery disconnect switch like #29866#. Best regards SVB-Team Bremen
