Telemecanique Sensors FSG2J24CP 40-60 PSI Pumptrol Water Pressure Switch, Grey Cover

This is the same old tried-and-true Square-D pressure-switch that has reliably trudged along, doing it's job, in millions of well-houses and basements all over the world, completely taken for granted until the water quits coming. There is absolutely no good reason for this switch to be close to the well-pump or pressure-tank; so long as it is screwed into the water system anywhere convenient, it will do it's job. Residing in a drafty poorly heated well-house, having such a tiny water-line connected to it, the presure-switch is the first component to slush-up and freeze solid, long before the larger water-lines even think about freezing. This is no longer a problem when the switch resides in a warm area. A reliable gauge should be visible in close proximity to the pressure-switch. Many times, there is nothing wrong with the switch itself, but crud has collected within the little pipe-nipple that screws into the switch and seals off the flow of water that tells the switch what to do. Instead of having to evacuate the system, add a ball-cut-off valve where the pressure-switch line connects to the system; thus, one can close the valve, screw off the switch, and clear the crud from the line; a brass-bristle shot-gun brush works good for this. Instead of hard-wiring the switch straight to the stiff solid copper wires, terminate the HOT wire coming from the breaker-box in a wall-box receptacle of the appropriate type, 220V or 110V. Using a flexible stranded cord with the appropriate MALE plug, attach it to the terminals of the switch via ring-terminals. A second flexible cord with a FEMALE plug on the switch side and a MALE plug on the well-pump side will take care of the switched side of the pressure-switch. Equipped thus, it is a simple matter to un-plug the cords, rendering the switch safe to work on, and service/adjust the switch or un-screw it from the water-line, without the hassle of un-wiring and re-wiring the stiff wires. My new switch came pre-set to 40/60 PSI. Two full turns clock-wise yielded 50/70 PSI Thanks for reading.

Great water pressure switches. I tried a different brand and went back as soon as I found this on Amazon. Long lasting easy to install great price.

I live in a solar powered off-grid cabin that I'm building out. My water pump runs from my 24Volt DC battery bank. Unfortunately, the pressure switch built into the pump head failed in less than a year. Reading reviews, it seems that is a common problem with the pump. I made the decision to purchase this Square D by Schneider Electric FSG2J24CP 40-60 PSI Pumptrol Water Pressure Switch as a more reliable solution at the recommendation of an electrician friend of mine. I had to plumb a tap from the output of the pump, to which I added the Square D pressure switch and a pressure gauge. I must say that the pump now starts and stops noticeably more cleanly so it had became clear that the old pressure switch was gradually failing. The contacts in this Square D pressure switch are rated 20 Amps. My pump motor draws a little over eight amps. I expect the new pressure switch will last for many years (as my electrician friend says it will). Before you notice that my installation is not NEC compliant without conduit running from the pressure switch into what will be the future wall, this is an emergency wiring to have water in the cabin. The conduit is on order and will arrive in a few days :-) Good catch!

This switch works as advertised once you tweak the differential setting. Upon installation the pump cuts in at 40 psi and out at 60 psi as it is supposed to do. After a few cycles I found that the switch was cutting out at 50 psi. I had to reef (clockwise)the differential spring down to almost the bottom of the adjustment. I was cautioned by Square D not to tighten all the way as the pump might not stop......that would be a bad thing. Basically I tightened the nut all the way and then backed off a couple of turns. This brought the cut off pressure to a bit over 60 psi. A few more tweaks lowered it to 60. I'll monitor the pressure gauge until I am sure that the cut off and on pressure remain constant. I am guessing that the initial setting by the factory is for the cut on pressure while the cut off is merely an estimate that needs further adjustment. In any event, the switch will stop short cycles of the pump which should improve pump life. I bought an extra just in case this switch becomes inoperable in a few years....probably happen on a holiday or Sunday!

I replaced an existing switch that had been original to my parent's house (20+ years). It was still working but getting unreliable mostly because it was short cycling due to pressure tank bladder failing (also original to the house). I ordered this 40/60 unit as a guess b/c the labeling and model number on the old one was essentially gone. I installed the new unit and appeared to work fine. First time I've worked on well components. As a suggestion to anybody doing this, check your pressure tank and the pressure gauge (I replaced that too) to ensure the cut in/out pressures are correct and everything else is working properly. I have noticed that since installing it, the contacts already have some wear on them. The one minor issue is the instruction don't indicate what factory settings are for cut in/out pressures. I can only assume that they're are 40/60 for this unit. The cut out seemed to be slightly higher than 60.

I installed this one to replace my 18-year old switch that was intermittently failing, resulting in no water and no pressure in my well tank. I suspect due to fouled contacts. It took quite a bit of torque to remove the predecessor, and I had to be very careful not to break it off and/or damage the piping. I also had to use a propane torch to get it to budge. Once off, the new one was put in easily with pipe thread tape. No leaks for the past several months. The instructions are a bit tricky to understand how to properly set the turn-off and cut-in pressures. I would not recommend installing this yourself unless you're comfortable with mechanical/electrical stuff.

I received the exact relay switch several years ago and it's been working perfectly. Thanks

This pressure switch installed well and checking pressure settings , it was truly 60 psi off and 40 psi on. Factory preset was right on the money. Good quality made in Mexico. Would buy again. This switch replaced a new Merrill unit (Chinese) which I had just purchased and was junk - could not adjust and returned to vendor.

Easy to use, instructions clear. Replaced old version of this

I liked it was easy to install had good wiring diagram

Good price for a reliable switch. I have been using this type of switch for years and rarely have any problems. I consider this a good purchase.

Quick shipping, easy install.
