If I made change in wiring, could I use this switch with a 12 volt battery backup sump pump?

Should be able to its just a on/off switch that open the circuit to turn off and closes circuit to turn on just like any switch you are just opening the path of power whether it be 110V or 12V

Assuming you make the proper connections, the switch should do fine on a 12 V battery pump. My battery pump has the same float switch and is rated for 10 Amps at 125V.

Actually, it could be a problem, but you'll most-likely be okay. See these two articles: https://answers.yahoo.com/question/index?qid=20090615011743AAahe5F (Why cant we use an AC switch for DC applications?) and http://en.wikipedia.org/wiki/Metal_whiskers (Metal Whiskers). The Yahoo answers explain that AC switches that are also designed for DC applications can be damaged by an electrical arc across their contacts and one of the people gave a rule of thumb of "25% or less of the AC voltage rating" - in this case 12V DC is 10% of the 120V AC and is safely in that range. The Wikipedia article talks about "whiskers" that can form on metal contacts. This has been noted in circuits where AC switches were used for a DC application when they weren't designed for DC use. Since this float is designed for AC, it ~might~ be using an internal switch that is not rated for DC use. However, it's not likely. I've looked at the specs for a ~lot~ of switches for my job and I would estimate that only one fourth of 120V AC switches are NOT rated for DC. So, three quarters of them are; and almost all of those are rated for 30V DC. A switch rated for 30V DC can safely be used in a 12V DC application. You also have to make sure that you are not exceeding the current (amperage) rating of the switch. But, again, you probably won't be.

I would think this is too big to use with a backup pump. This is pretty large. It is meant to be a primary pump float. I am not sure if a change in wiring would work as it is meant to work on AC not DC. Why not just get a DC float switch from watchdog?

If I understand your question correctly, you're asking if you can use one check valve for both the sump pump and the battery backup, the answer is yes, as long as the two line tie into one line, but the system won't work as efficiently, you loose pressure from either pump, I had the same configuration and added a check valve for each system and the pumps work much more effectively and less noise from the systems.

As long as your input into the pump is 12v DC you should be fine. That is my educated guess.

It should, I use it to switch on a 12 volt pump daily. I have a 12 volt battery and a 45 watt solar panel along with the pump, and this works pretty good. I really like it. Used it for 4 months so far, no problems.

No; Oprerating voltage is fixed for this type of electrical motors. Probally a 12V pump will burn out with 6V source and vice versa

I suppose it is possible to replace the switch without removing the pump from the sump well. But it seems far easier to cut the discharge pipe with a hacksaw, replace it on a work bench, and reinstall the pump using a conventional rubber sleeve with double hose clamp to cover the cut in the pipe upon re-installation. Biggest caution: be sure to note the wiring when removing the old switch or burning out the new switch is a distinct possibility.

No. You will damage the unit. This is a switching power supply designed for a 12v output only.

It would probably work but I would be inclined to go with a solid state switch. They use a probe mounted vertically in the skimmer that would cut power to the pump in the event that the water goes below a certain level. It allows a lot more accuracy than the float type switch.

I can't say for sure, but that current has to go somewhere. It might over-heat something in the line. But, at a max about 3 amps, it's probably ok. Think about why you want that switch in the first place. What is it going to do for you that the charge controller won't?
2070266
for sure. or you can use a controller that changes it back to 12 volt. controller is key either way

I'm sure you could it's just an electric switch. You will need 12 volts to power it. They have a 110 version also.
1806987
Yes as long as you put only 110-120 volts & no more than 15 amps. The output is only 15 amps from the switch.

No. The wet switch has to be manually reset after it comes in contact with water. Try something like this. Search amazon for HC8000 Sump Pump Controller (Float Switch)

Your float turns a switch on and off on or near the motor. If you can lock the switch in the on position (many options), and your pump runs full time, you can use this switch by plugging it into the outlet first and then plugging the sump line into the control. Directions aren't the best but mine still works. Good for up to 14 amps. I'm always cautious with low stock items. They could be returns but Amazon backs up their products.

If you have a 12 volt power supply and switch yes, I used a 12 volt 4 amp power supply to run this and one other amp

Yes. Switch operates on pressure build up in tank. Doesn't care what type pump. The contacts are separate to control the two hot wires. When you restart circuit, you may need to hold the priming lever down until pressure builds up the first time. Be sure to remove power from circuit before you work with it, each wire usually is 120 volts and 240 between the two.

yes but you need to wire the batteries together the proper way, check the internet for 12 volt to 24 volt dc wiring diagrams you will want to maintain 12 volts not 24, this will extend your draw down time on your batteries
