The real industrial switch of this type are expensive, having a low-cost alternative for DIY is a great option. This is a typical changeover switch. The wiring is typical, and all the details are in the supplied instructions. The 20A has a smaller size than the 20A model, but quite nice.The installation is made by mounting the switch through a hole on a panel, with relevant holes for screws. The switch is not meant to be standalone, it needs to be in an enclosure. In my project I already need a power supply, solid-state relay, so it is a good match. If you only need a switch, then you may find a similar one with an enclosure.There are no certifications valid For Canadian Electrical Code, so this is good for hobby projects, but would not be legal for high voltage.

The Keymoo 20A Rotary Changeover Switch is excellent.It comes with all the necessary mounting hardware.The build quality looks very good.The contact resistance is very low.These are good quality switches for high amperage switching.Recommended.

Keymoo 20A Rotary Changeover Switch can be used for many things. I got this to repair my old crusty fan from 1992 that had a broken switch. The switch came with all the mounting and electrical hardware required to install the switch. The switch had solid feeling detents for each position. This switch has three separate current paths to work with. Since I was switching the same power supply to the inputs of the fan, I ran a jumper wire to three terminals on one side of the switch and the fan input wires to the three output terminals on the other side. This is a good switch, and it works well.

I got this for my off-grid cabin. I needed something to let me switch from generator power over to my solar/inverter power without having to unplug extension cords. This is perfect. I have #1 for Generator, #0 for All Off, and #2 for my LiFePo4 Battery/Solar/Inverter system. In the heat of the summer, I have to run the generator to run the window unit air conditioner. But in spring, fall, and winter, I just run lights, fans, TV, radio, water pump, etc, off of the solar system. Most of the lights and fans are 12 volt and do not need the 120 volt power, but the TV, StarLink satellite, power tools do. This was a great price and it quality built. I would definitely recommend this, if you need a changeover switch.
