- This is a rotary changeover switch. It allows for a single input to have two outputs or two inputs to have a single output. It can even have two inputs and two outputs. I show the simple way to test the terminals operated by the switch and how to wire for a double input single output.
I did buy this on Amazon here:

This was exactly what I was looking for! When I bought this switch I was under the assumption that this is how it would operate, before learning more and that what I want is a DPDT on off on selector switch. Thank you so much!
Finally sound what I'm looking for, single input with dual output. Just need to figure out how to wire it.
No kidding!
Thats a smart idea. Im a visual learner (why i watch u tube) and had to watch twice to get it. A wiring diagram would be great here. This is a great application for a transfer switch.
thank you exactly what i was looking for for my van install, UPDATE i wanted 2 outputs from a solar array input so i could choose where the solar charges either to the leausre batt or a power bank. by doing the opposite to what you did ie connect the odd numbered posts in same way you connected the even numberd post and it works big thanks
Nice tutorial. If you want to find continuity, you can always use the continuity mode on the DMM. It looks like a volume icon. Whenever there is a connection, it beeps.
Interesting setup. Thanks for sharing
Yes.
I can set up one solar array with that switch to charge up my solar generator either in my Shop or my home as needed. With circuit breakers wired in for additional safety. Thank you. A single PV input, two outputs as needed.
Thanks for the ohms trick it helped a lot.
Very helpful. I had the two power sources right but didn't know about the two jumper wires. After putting them in it worked fine.
In my ext cord black in hot and white is common. You used red as hot.
Great simple tutorial. It's quite a good rating for this price of switch.
It's worth noting that often these switches are rated at much lower DC voltage or current than AC. That's because a DC arc doesn't self-extinguish because there's no zero-crossing 100 or 120 times a second. That can cause the contacts to weld themselves together or just burn and leave a carbon later on them. Probably not a huge problem for your setup with a small DC voltage from a few panels.
You should consider continuity test instead of resistance! Great review keep it up.
Kinda smart, nice and succinct video.
Excellent.
I have replaced my broken 3 way fridge (12v/240v/ gas.) in my campervan with a small 240v compressor fridge (50w) This works fine on campsite hook-up 240v. When driving I want to use an inverter powered by the 12v cable (was for 3 way fridge)which is powered when the engine runs. Can I use the rotary changeover switch to do this ? and how should I wire it? Will this switch allow the fridge to work on hook-up 240v without 240v going to the inverter? (or does this not matter!) Thanks for any help you can offer.
Hi there. This is such a great video. There is not much in the way of directions for these. You explained how you were going to wire them up but you never showed the wires actually attached. Can you make a diagram or show the pictures of the actual wiring. That would help. Thanks.
Terri
good vid thanks man!
Need to see the wiring for a switch to do one input to two outputs ....I'm doing the same wiring from my solar array two my charge controller or switch to my eco flow delta max on the xt60i plug, exactly what you did on your second setup the 12v setup, hope the wiring diagram comes with the switch
I have a similar situation with two lines and one load. I am much more of a visual learner. With the information you shared I have created a diagram. Would you mind reviewing the diagram and tell me if this is correct? Thanks for all your effort on the video.
Hi. My application is exactly the same as yours; solar panel switching from position 1 to solar controller and position 2 to ecoflow power pack. I'm still a little confused with the wiring. So 2&1 will be position 1 and power pack, 4&3 will be position 2 and solar controller. Am I right so far? Does the feed in from the solar panel have to be across the remaining 4 terminals? 5,6,7 & 8? I have exactly the same switch too. TIA
Just spend a day to find diagram of a 4 pole cam switch. What i learned they are just on/off switches. Once you get that into your head. It’s not the radio type multi input one output switch. It is one to one
I am going to be using this switch to "select" between a dryer outlet and tesla EVSE (ev charger). This allows me to use the 10amp romex that runs to my dryer for dual purpose and it won't overload my breaker. I'll report back when I finish the project.
What kind of wall box can we use for home/residential use?
Great video, this is exactly what I needed. I’m doing something very similar. In your upper switch, did you buy the 12 terminal variety instead of the eight pin? Because you have AC current coming in and out, so three wires…? And then you do the same thing as you did in the video with DC, just short the output sides, and then wire one input to each of the options?
I have 4 12v lights I want to switch from (off - all 4 - just 2). They're currently wired to all switch on together with a relay that switches with the car ignition. I don't want them always on when Im driving so I want to switch them. I can easily make an on-off switch for all 4 with the power leads and an on off from two lights to all four lights, but ideally I want it in one neat switch rather than 2. Would a rotary switch work for that?
Ok. Good video.
How do I wire one of these for a reverse forward dc motor with off with the switch straight up? Basically like a DPDT toggle switch.
Thanks,
Paul
Very noice !
Wow Radio Shack multimeder I think Radio Shack closed here in my town about 6 years ago
Nice video.
Can I use this for dc current?
Thanks
Thank you! I was getting frustrated because the blue seas rotary switch instructions dont mention using a jumper wire on both outputs if you only want to use a single output with two inputs. The diagram shows a solid line between them, and i was assuming thats what the solid lines meant, but not being a pro, i didnt want to chance it and connect them and possible destroy my new inverter.
I am not sure I fully understand this. I also have 2 sources and one output. Mine is either from a breaker which is powered by a generator or from land line. So if I place the white and black in the input side, on top for one source and on the bottom for the other. What do I do with the grounds from each source.
The second part I don't understand I need a power neutral and ground from the output as it goes to a mini split ac heater. So if I need 3 wires how does the other end connect to the changeover switch? Where does the ground go?
Nice video… I’m trying to do the same set up but I’m a little confuse…Where does your ground wires go in the switch?
I have the same question, will post it as well.
You want grounds to always be connected. They don't switch with the on/off. Same way with nuetral. Only hot wires are switched. That way if any stray voltage happens you are still protected by the ground. Please someone chime in if I have it wrong.
@@chevydavidson9220 So the ground literally just passes directly through then.
Hello everyone! Reaching out to someone that can share the wealth of knowledge, in regard to automated process control. My boss came up to me and asked me to install a master contact, and a selector switch, so we can put all the instruments, devices, pumps, conveyor motor, motor drives, onto to that relay contact, all of this on a down line independed circuit. Any ideas- any one ? Thanks I will appreciate it
Great video. How many volts does your solar input produce? Any issues with the switch and voltage arcing?
This is just a 22.5v panel. No issues with arcing.
Why didn't you sit the meter and continuity the little speaker one click over so it would have just beeped?
Is it possible to do 3input and 1out put ...
Seth,
Please.... Cable management. It's so much easier to just do it when you're setting it up!
Yes.... cable management is my worst nightmare.
I like your video, however, I am not very lecky savy? could you make a diagram with what wires will go to which number exactly as I will buy the same switch? I wont to supply power from my inverter when the is a power cut and then switch back the grid power when we get the power back on. Hope you see what I mean. thanking you Roger
Hi I’m straggling to connect Salzar 63A 2Pole
Nice Video . If i wish 1 input and 2 outputs would I then use 1-3 as positive and 5-7 as negative ( with bridging ) then use 2-4 positive ( oulet 1 ) and 6-8 negative ( outlet 2) . Basically using power from solar panel in and it gets split into 2 outlets to supply power to 2 seperate DC loops
That's exactly what I want to do. Did you find the info anywhere and have you a link ??
Sorry no an electrical guy, bus isn't there a third (ground) wire in there somewhere? for each incoming power source? Thx
Hi,would I be able use this switch coming from generator panel to turn off outside inlet plug and turn off my inside inlet plug so I could use either one I wanted,30amp generator plugs I have.thanks
This switch is rated for lower amperage. You are going to need a larger switch to handle 30amp AC.
@@LandtoHouse ok thanks ,could you recommend a specific one for me.
@@brucevantassel0 My dad actually just got a switch box for his generator. It has 6 dedicated breakers and switches for each. But sadly I do not remember the name.
Comment faire le schéma normalisé du compteur électrique monophasé
My only question is the ground wire and where it connects.
You would need a 12 pin switch
Where does the ground wire get hooked up?
I was hoping to learn where the ground goes as well??
In my system I installed a ground to the building and to the ground of the electronics. Basically the ground is common on both sides of my power.
Thank you, I see how and why you got around grounding the switch. Big fan of your work by the way. I've celebrated 7 years now, full time off grid. Came to your channel for help on multiple occasions. Thanks for everything
The design of this relay is two power INPUTS to one power OUTPUT...example: 12v battery and 110v shore power go into relay switch, select which power to be used, with the selector knob and done. The jumper cable explanation makes this use confusing.

Confusing.
I m sorry you didn't explain properly

Cool.
