Changeover Switch LW28-20 3 Positions 8 Terminals Universal Rotary Cam Selector Latching Switches 550V 20A

I used it to create an inverter bypass switch in my travel trailer. No problem with the 12 gauge wire. Solid construction. I am confident that it is a quality piece. No issues and I’d certainly buy it again.

I used this to have an option to connect my furnace to my portable generator. Once I figured out which way the circuit went (which is totally on me) it worked fine. One position, furnace runs normally. Other position, plug in an extension cord and the furnace still works. We'll see how it does for durability, but for now pretty happy. Fits in a 2-1/8" electrical box, mounted to the cover.

Excellent switch. I recommend it

Poorly constructed. I've been in the Electrical business for 40+ years and have extensive experience with Hand-Off-Auto switches. When this switch failed to operate (no make or break contacts in any switch position) I decided to disassemble and see why. What I found was the gap in the Cam (see picture) is not wide enough for the full travel of the switch positions. Even though I was extra careful, unfortunately I lost a contact assembly and this is now junk. I can't in good conscience return

I have not wired a switch like this before, and it was unclear to me where "in" and "out" should be wired. I wanted to have two power sources (house vs solar) and one output (router). After trying a couple of set ups that did not work, I emailed the seller. They responded with a clear diagram for my application; very good customer service. I wired it that way, and it works well. Seems like a solid switch with good contacts that tighten well. As others indicate, it has few instructions (in Chinese), but the customer service made up for that. It works well for my application.

Great quality product, well made, easy install,would definitely recommend this product.

Excellent quality and value. I have paid considerably more for the same.
