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.

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

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.

Well made
I installed this switch on my pool pump system. It’s fairly easy to install, and feels heavy duty, and most importantly, works well. Delivery was fast, just a couple of days.

Nice enough switch, but...
The switch is nice enough, but it smells to high heaven. Requires some baking soda. Sun and air won't do it. The spacing is really tight and 12AWG is a pain. Once you get pasted that it works good.

レトロな見た目で一目ぼれ
このレトロな見た目と操作性が欲しい方には、減点要素はないでしょう。 デカいし、ごついし。ただし、そういう雰囲気が必要な場所にはぴったりです。 説明が不要なくらいシンプルな操作を間違える人はいないと思います。
