Came with no wiring diagram but someone else posted theirs and it worked perfectly. No issues with and I'm happy.

worked great on boat, hooked up battery charger to one side and used jumpers lines to other terminals, then went to the three batteries. one charger easy to charge all 3 batteries by rating the switch. 4 starts because it was a little big for my application

I needed a cam switch that was a two pole 3 way switch. I was using 16 volts to control switches and 5 volts for leds.This unit was perfect for me. I had bought a similar switch on Ebay that was advertised as 2 pole but was just 3 single switch contacts.

I have purchased several different Baomain changeover switches. In all cases, instructions are nonexistent and the wiring diagrams are extremely confusing. For the switch to function as intended, one needs to provide external jumpers between the two "position 0" terminals. My friend who is a retired Electrical Engineer couldn't understand the diagram. If you look into the switch next to the wire connections, you can actually see the contacts open and close. That's how I finally figured it out. I've had one instance where the switch received was not the one ordered, even though the box was labelled correctly. Also had an instance where the wiring diagram has not matched the switch. I have not had any problems with the functioning of the switches. Learning to use them was an adventure,

Looks great, functions as it should, & gives a solid "clunk" when switching between all positions. No instructions but easily sorted out the terminals/dial positions with a multimeter set to continuity. This switch provided an easy solution to my problem of having two welders but only enough room in my garage's breaker box for one 220V line. With my one 220V line going to the switch (had to run jumpers to each "line-in" terminal), I ran two separate 220V lines out from it to 50A outlets for each welder, plus the availability to wire in a 3rd 220V outlet for a plasma cutter in the future. No more reaching behind my welding table to swap plugs at a single outlet. Now I can go from MIG to arc welding at the flip of a switch.

I purchased this rotary cam switch with a specific prototype project in mind. The description of some similar devices left me unsure of some details. This item appeared to offer all of the details that I was concerned about, including the contacts schematic diagram. The "0" position has all of the contacts OPEN. Each of the other positions CLOSES a different pair of contacts. NOTE: Stated dimensions are incorrect. Should be: HxWxL = 2.6"x2.6"x4" (panel mount depth = 2.8")

I used it as a transfer switch on a boat. The Four position permits shore power, generator, inverter feed and all off. Works well, wish I could find the video to show its performance.

Works and looks just like the Blue Sea version (9010) for 1/5 the price though the ports aredifferent than the one I was replacing. I used my multi=meter to determine which ports had tobe jumpered together and made them myself.The instructions are in Chinese and jumpers are NOT included. There is a diagram includedthat (basically) shows which terminals should go together but use your multi-meter to verifybefore installing.

SEEMS PERFECT FOR THE APPLICATION. WAS PLEASANTLY SURPRISED THE MOUNTING HOLES WERE IDENTICAL TO THE ENTRELEC UNIT WHICH I WAS REPLACING.DO YOU HAVE A MODEL WITH 5 SELECTIONS ??OTHERS I HAVE NOTICED COMPLAINED ABOUT MIS-LABELLED UNITS. I BELIEVE THAT PROBLEM IS SOLVED .MY UNIT WAS LABELLED CORRECTLY.AND AS TO THE GENT WHO SAID THERE WAS NO COMMON, WELL YES YOU MUST TAKE TWO JUMPER WIRES AND DO THAT PART YOURSELF. NOT A BIG PROB. SWITCH A GOOD ONE.

So far so good. Have been using this switch to change loads from my solar grid. Works well and no problems to date.

Had a 15A-240V source for the air conditioner which now gets switched to a baseboard heater for the winter.Wonderful quality. Very much like the industrial ones.

I had thought it was 3 phase. When it wouldn't work for me, I was completely refunded. Thank you. This is a good company to work with and makes quality products.
