Will this switch handle 0-240VAC, or *only* 240VAC? -- i.e., can I use it with a 120VAC pump?

I believe the two outer contacts are "voltage in" and the two inside contacts are "voltage out" so in theory only installing one wire on "voltage in" and one wire on "voltage out" should be fine....but this is electricty I would ask a "PRO" In fact they (SQUARE D) probably make a switch just for your application (120v). Search Amazon or Google it.

It's a "dumb" mechanical device that balances water pressure against a mechanical spring. The contact switch is purely "dumb", just sits on top of the mechanism and opens or closes as the rocker trips back and forth with pressure. There is no electrical connection from the switch parts to the water parts. It really isn't any particular voltage, just two contacts that open and close. You can hook up both hot wires of 240V or both line and neutral of 120V or you could hook up 24V or 12V. Anything below 12V I probably would't use this because the contacts are kind of rough, they need at least 5V to "weld" together when they close. If you used 2 or 3 volts you might find it intermittent. It's a "dumb" mechanical device that balances water pressure against a mechanical spring.

Since the switch operating force is pressure water/air, voltage xx in = voltage xx out. So, the answer to your question is yes

Just did another check on original packaging and it states "1½HP 115VAC 2HP 230VAC".Scan of packaging here http://i305.photobucket.com/albums/nn210/Mannypl/SquarePressureSwitch001.jpg

I have used many 120 volt Waterwise model 4000, or comparable model for years and have never seen one equipped with a 120 volt to 220 volt conversion switch. A Waterwise Web page indicates this model is indeed available for 240 volts / 50 cycles per second. Suggest you phone call them for details: 1-886-852-4268

This switch is designed for 240 volt input. It is not adaptable to 120 volt unless you would be OK with only 3 circuits on this 6 circuit switch. Best to get the proper switch.

yes that's how you get 240 volts. There is a switch inside to run the timer electronics on 120 v or 240 v and you can have it switch one line or the other independently or together for 240 volts. I am using mine to turn on a 240 volt 3/4ph pool pump motor. The CR version is the outdoor model case.

I have not found any information in Current Capacity for this switch. I would suspect between .75 and 1.5 amps at 120 VAC. I played it safe and have the switch activate a small ice cube relay that needs about 20 milliamps at 120 VAC. I would suggest doing the same.

I'm pretty certain it is only 120V. I did not see a switch or any indication that it can be changed to 240V.

You need to go with the professional switches by ivac rated for 240volts. You will need a "tool" switch and a "vacuum" switch. http://www.amazon.com/gp/aw/d/B004JK90QW/ref=mp_s_a_1_8?qid=1423492153&sr;=8-8π=AC_SX110_SY165_QL70&keywords;=ivac&dpPl;=1&dpID;=41q9Ln77e2L&ref;=plSrch

It's just a relay so will switch anything you want. It's rated up to 120 V AC but will switch DC of lower voltage. Being a relay the switch is completely independent of the mains which is used to operate it. Hope this helps.

Not really sure; suggest checking with a licensed electrician. I am using this switch as a replacement to an identical one that controlled my 1hp pool pump, a use that this switch was primarily designed for.

This pump runs on 110-120 volts. If your adapter does not convert the voltage from 240 to 120 then it will not work. You may need a step down tranformer to convert the voltage.

Yes, that's exactly what happened to mine too. I had a 120v one which I was pretty sure may not be able to handle the equipement I had - the filter, pump and heater. I dismantled my broken one and looked at the back and saw that it had a similar voltage rating to this one and so i bought this ... installed it myslef and worked fine for the last few months now!

It cannot directly be connected to the you will need to use a step down transformer (this breaks the current down from 110v to 12v) after the Honeywell switch, else you will damage the pump. You need 110 - 120v input for it to function properly.I hope this helps.

Sorry about the delay. I deleted all amazon email thinking it was all junk.Didn't see this until I was deleting stuff from my phone. I dont' think it will work on 240. There is no switch to allow changing between 120 and 240v.
1593555
I would say yes,I never have but, mine has run our electric range (240 v) our pump is 120 v.
1150864
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.

Unfortunately, no, it won't. This is from Honewell's webpage for this model: Does not work with heat pumps, multi-stage heating/cooling systems, and electric baseboard heat (120-240V).

I am using this pressure switch on my 220v 60gal compressor, not sure how many amps the motor is rated for though.
