Does the job, best quality

Okay, so let me dive into why I'm totally wowed by this float switch. I run a water business and, being fairly new to this, I'm learning on the fly. I've hooked up tanks as alternate water sources to homes before, but adding pumps was new territory for me. My background? Sump pumps for basements and sewers, but tanks? That's a different ball game.Here's a little insight for those who might not know (like I didn't at first) – standard float switches typically trigger pumps to drain water when the float is up. But for water storage, you need the exact opposite. And yep, I learned this the hard way. Wired everything up, standard style, and then hit the panic button when my pump went berserk every time I plugged it in. Rookie mistake, but hey, we all start somewhere, right?Then I discovered this float switch, and it's a total lifesaver. It's versatile – you can set it to work whichever way you need, up or down. This little gem completely saved my project.A bit of background: I never planned to offer this as a service, but living in an area with limited technical support, I figured why not help out where I can? So, here I am, learning as I go and sharing the wisdom.Long story short: If you need a float switch that adapts to your needs, this is the one you want. It's a game-changer, especially for self-taught folks like me!

Its not bad for the price. Bought 2 of these(2017), so when the first one failed in 2023, I installed the spare. I then ordered a new spare. I don't directly run the 240V 2HP well pump, but use a 110v contactor through this float switch, so the small microswitch in this float does not have to deal with any inductive loads.

Needed to replace well tank float switch. This one is lighter and easier to install the the previous one. Float weight could have been easier to install as it did not come with instructions and I broke the cable lock ring. Otherwise it is working great. Next is seeing how long it lasts.

Worked great, until it was 3 months old. No longer working, water flooded all over! I'm unhappy, have a mess, and need a new float again.

For the price, this switch beats the competition in offering a N.O. and a N.C. option -- it can operate to fill a tank or to empty a tank, depending upon which two of the three wires are connected. That's great. The switch was just put into operation and what is worrisome: the size of the individual wires may be large enough for the current, but considering these switches are often outside or in wet areas, corrosion won't have too many wire strands to damage before there's nothing left. The biggest issue during install was the fact that the switch 'pod' seems like it must move through nearly an entire 180* up or down, before the contact ball rolls into the opposite connection point. In a shallow watering trough, that means you can't have very much cord between the pivot weight and the switch pod or else the switch won't operate. If there is less cord, the smaller section of wire will have to travel through a greater range of motion each time, which means metal fatigue should occur sooner with the small wires. Time will tell. The switch comes with a generous length of wire and reasonable instructions/diagrams.
