Baomain Universal Rotary Changeover Switch with Master Exterior Box, 660V 20A 3 Position 2 Phase,CE Approval, SZW26-20/D202.2D

Me funcionó perfecto para intercambiar entre 2 bombas centrifugas a 120V de 16 amperes, aunque el espacio es pequeño logré cablear todo con calibre 12 awg, el producto es de gran calidad y trae los accesorios necesarios para conexión. Apenas para considerar que solo trae 2 orificios de salida con chiqueadores pero ninguno de entrada, entonces tuve que hacerlo manualmente.

This is a very well built and nice switch. The housing is small, but to fix the problem, we added a junction box and from pig tail wires coming from the rotary switch, we connected all the wires inside the J Box.One issue we noticed that the wiring diagram the comes with it appears to be incorrect. Position 1 connects #1 & #2 lugs. And Position 2 connects #3 & 4 lugs, not as shown on the wiring diagram..

Seemed decent quality, works perfect as in the switch for what i needed if for, but had to take switch with cover and mount it on a bigger PVC box so i had enough room to mount it properly with all the wires

Using this to select power from either a generator or line/household power for a trailer. Unit is good and rating (20A, 600V) matches my needs.Regarding safety compliances: There is NOT a UL/CSA certification on the device. The exterior of the cardboard box has a "CE" (Europe compliance) marking on it, but the label on the switch itself has the "China Export CE" mark on it. From these markings, I tend to believe that they haven't been through safety certifications, but the unit appears to be good quality, so I'll use it.

Works great for what I needed
