Changeover Switch LW28-32 660V 32A 3 Position 2 Phase Universal Rotary Cam Selector Switch with 5 Screws

Awesome compared to all of the other ones that I took a look at, the set up is fairly easy it’s very robust. Wiring is very easy if you stop and think about it, wiring instructions are not very good but there is a lot of Internet help. I am running power through a VFD to the switch that I can either use my 3hp / 3 phase South Bend lathe For my Cincinnati 3hp / 3 phase dual post grinder. The switch handles heavy duty wire and is robust when you change from one leg to another leg. I tried two other switches (different brands) before this neither of them worked once again neither of them had instructions. I am a home hobbyist and I run 3 phase machines out of a small garage and this product really helps to keep everything aligned. I installed in a large plastic electrical box that I purchased from Home Depot and used all heavy duty wiring and connectors.

This is a great product and it works well. Other reviewers have commented on the lack of instructions, and they are spot on. There are no instructions that can be understood by humans. But if you look carefully at the pin diagram on the switch, and if you confirm it with a VOM or continuity tester, you'll be good to go.I used this switch to connect an outside generator to the refrigerator inside my house. I needed it to switch from the house circuit to the generator, when I lost electricity. It works perfectly for that purpose, I couldn't be happier. In the photo, you'll see a triple gang blue wall box, a changeover switch, some faceplates and a recessed power inlet. I finished it off with some 1/4" high black adhesive vinyl lettering:Inlet: https://www.amazon.com/gp/product/B002XDQAA6/ref=ppx_yo_dt_b_asin_title_o08_s01?ie=UTF8&psc=1Wall box: https://www.amazon.com/Carlon-B355R-5-72-Inch-2-79-Inch-3-69-Inch/dp/B000BQOXAG/ref=sr_1_7?dchild=1&keywords=3+gang+retrofit+wall+box&qid=1614810752&sr=8-7Lettering: https://www.amazon.com/gp/product/B002XIHXJS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Now, when I lose power, I simply plug my generator into the power inlet and turn the transfer switch to "GEN".

Take your time and read carefully to avoid unintended shorts or open. Documentation accurate and works as advertised!

I've updated my review below. I put in the replace request and a new switch arrived a couple days later. That was a fast turnaround. I've tested the new switch with the ohm meter and it works as expected.When it arrived, it was in position 0. It will switch to position 2, but not position 1. Also, in position 2, ALL the lines for pos1 & 2 are connected, which is not correct. The attached pic shows the switch in position 2, with an ohm meter across screws 1 & 2, which should be Open according to the grid but are Closed.I'll upgrade this score depending on how easy/difficult it is to return for a replacement.

Good quality build, installed it in a robot as a power off/battery/charge switch. Would recommend

Did the job nicely!

I used it to switch between two source of power and the design is good but not perfect. I scare that wires comes out of it with little moving. I thighed it as much as I could, but because of the kind of wire holder on switch I am not sure about it.

Not overly impressed with the quality of some of the parts of this switch. The washer on the terminal that holds the wire in broke in half when tightened enough to hold the wire. One of the nuts that is supposed to be captive in the housing to hold the faceplate on was loose and had come out.
