Universal Rotary Cam Selector Changeover Switch, 20A, ON-Off-ON

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.

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.

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

Well built and sturdy switch.

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.

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.

Facile à monter et bien expliqué

My only grip, as others have observed too, is that the mounting box is a little too small IMO. Cables can only just be fitted in place within the mounting case. The kit includes all that you need but it's strange that only 2 cable outlets are provided when you really need 3 surely? (Power in, power out 1, and power out 2). The lack of an earthing option also means that you need to provide your own connection block for the (3) earth cables and then squeeze this in too. However, it all worked and I was just about able to then secure the rotary switch to the casing (just) - albeit I used 1.5mm heat proof cable. My use was to be able to select 1 of 2 power options for my immersion heating element in the Hot Water tank: Solar control, or (overnight cheap rate) grid power.

Works as it should
