Review: Le doy las 3 B, ( bueno, bonito y barato) - Este insterruptor manual me sirvió en varias ocasiones para hacer transfer switch, soporta buen amperaje y lo utilicé para a través de un contactor magnético desconectar la entrada del servicio eléctrico, así no se juntan las 2 corrientes cuando uso un inversor o una estación de energía solar.
Review: Nice switch - I was getting interference on my humminbird solix from my trolling motor through my on board charger, this switch allowed me to isolate the charging connections to prevent cross talk.

### ⭐⭐⭐⭐ Does job for low cost
*by L***R on January 27, 2026*

Great value. Instructions on wiring set up, not so much. Very tight space to accept #12 wire. But is very function with patient wiring.
