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

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=1 Wall 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=8-7 Lettering: https://www.amazon.com/gp/product/B002XIHXJS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Now, when I lose power, I simply plug my generator into the power inlet and turn the transfer switch to "GEN".

This switch works great, especially inside the matching wall-mount box. I used it in my laundry room (on the 30A 240V dryer circuit) to send the power either to the dryer or our new EVSE charger. It's now easy to change from one to the other. It comes with all the necessary screws and fittings.

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

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.

I like this switch. I’ll purchase more as I need them. It’s easy to wire and has a strong click when selecting position. A good solid click makes all the difference. It’s easy to find instructions on YouTube if you’re a visual learner.

Just what I was looking for. Small and compact. Good price

Quality build, quality materials.

By accident I finished up with two similar switches. One advertised as "32A" (660V 32A 3 Position 2 Phase 8 Terminals) and one advertised as "40A" (660V 40A 3 Position 12 Terminals). On checking them, BOTH are physically labeled 240V/2.5A and DC1.4A (legal labels and therefore Volts and Amperes) and appear to have identical switching modules, the 12 position has one more layer than the 8. This legal current label rating is by code for the entire switch. Electrical codes do not sum the number of contacts, but it seems advertisers are doing that. The documentation is specifically unclear as to the power handling of each individual contact set. At labeled 2.5Amps x 12 contact positions the current handling of the entire switch is still 2.5 Amperes. Even if using 3 of the individual contacts in parallel (not recommended) that is only 7.5 Amperes total switch handling! To put it in perspective: say you have an air-conditioner load of 50 Amperes. Would you go out to a big box store and buy four 15 Amp light switches (for a total of 60A) to turn the a/c on and off? I do not think so, and common sense will tell you this option is not safe. That is what is happening here. These cam switches are legally labeled at 240V/2.5A and DC1.4A and should not be used for currents higher than that. There are some other similar looking cam switches - and these appear to have the same "add more contacts and increase the advertised current handling" issue. For the record, in case your house burns down or somebody is injured due to this false advertising, I have filed a complaint with Amazon. Electrical codes are for the safety of all.
