HOW TO INSTALL FLOAT SWITCH FOR WATER PUMP

- A float switch detects the level of a liquid in a tank or container. It floats on top of the liquid surface and acts as a mechanical switch as the liquid level goes up or down. They control devices like pumps (pump water in or out), valves (open or close inlet/outlets), or alarms to notify users. They are cost-effective, reliable, and can be used with a wide variety of liquids.
float switch provides versatile multifunction control for pump
protection, pump control, 3-way valve control and tank water level management. Operating as a single-pole, double throw (SPDT) switch, the
multifunction float switch is used to protect pumps from running dry, to
add water from an outside source such as a well when the water reaches
a minimum level, or to activate a pump or valve to drain the tank when
the water level reaches a maximum level. The switch can also be used to
control a 3-way valve for a backup water supply.
In short, a float switch is a mechanical switch that floats on top of a liquid surface. As the liquid level goes up or down, it moves vertically with the liquid level. Depending on the counterweight and pre-set trigger, the mechanical switch opens or closes allowing an electrical current through it to the connected device. Typically, this connected device either stops or starts the inflow of the liquid.
A float switch consists of a hollow floating body and an internal switch, also called a sensor. The most common internal switch is a reed switch, so there is also a magnet inside the body. There are other types of internal switches, but the working principle that they open/close due to gravity and water level moving the float switch vertically up or down is the same. Therefore, the mechanical switch creates an open or closed electrical circuit.

In installations where the float switch is lowered freely into the tank, a
weight will be required. An optional cord weight is available for installations where the float switch is not secured to a fixed object such as
a pump pressure line at the desired water level. The pump weight is
installed by attaching the supplied clip onto the desired location on the
cord and then the weight is pulled down
the cord, tapered end first, until the clip is
tightly embedded inside the plastic weight
housing.
An excellent tutorial. I followed it step by step and everything worked. My float switch had three wires: blue, brown and yellow/green. The brown was the wire to tape off and not use, blue went to terminal 3 and yellow/green to A2. Hope this helps someone.

Wow! This is video very informative and the best tutorial on the topic for me so far. I really appreciate it. Thanks for sharing it with us. Your ability to add the circuit diagram to your work makes you a top notch...
watched 20 vids on this topic...this is the first one i can understand...lol great graphics!
Thank you just what I needed to know.
thanks for this brief and very clear video. just the way i wanted it to be. its been a long time that i like to install a float switch by myself but not very convinced yet because of my lack of knowledge about stuff like this. i have also watched a lot of videos about this matter but none were conducive enough for me to abosrb the details. thanks and kudos!
Very helpful. Thanks for sharing.
the explaining was so good but can i get a diagram for this control?
great video. super easy to understand. hope to see more
Thank you so much… going to instal one tomorrow in Libala
very educative video thanks
thank you for easy understanding the wiring diagram
Fantastic Video. Can you do one whereby you connect two float switches in two different tanks. One tank is the storage (on the bottom) the other is on a Tresstle...
What modelling software are you using?? So clean and simple!
Best video on how to connect float switch using contactor ❤❤
Well explained,need more please
awesome video and very helpful thank you💯
Wow! This is very educative and thanks for sharing it with us...
Very informative and learning video
Excelente maestro!
Indeed it a wonderful video. If provide me with the refrigerator repair techniques too brother. You are really good at Electrical
Nice graphics. Thx. If incoming neutral wire is open , in the float switch wire we will get live supply. Though insulated it may not be good for safety reasons. Please reply
Thank You 🙏 So Much ❤
Thank you sir and very helpful to me and i have questions sir, how about trouble shooting is not working floatswitch.? Either to check the switch conductor or water pump? And more power!
Is the neutral run through the float switch? Mine is a simple two wire device. Seems safer to interrupt neutral with the tank float switch than 120v run through it.
Its simple,and that is actually its done.
Great video, thanks
Hello and great video.I will be greatful if tou can help me. I have pressure switch which is operating with 230V Ac. I need to shut of a gas solenoid valve which operates with 230V. Shall i use a contactor
Thank you!
Wow learned something
😮excelent installation
So cool good lesson
Thank you i am from Somali 🇸🇴
Yeah float sensor used for tanks ( fuusto- booyqda and wells ( ceelasha )
good job
Thanks very much
Sharing is caring.. thanks a lot, sir..
Thanks for the simple clear video. Is it safe for the mains voltage to be connected to the float switch which goes into the water?
Personally I don't think so, if the flow switch leaks it can be disastrous if you don't have earthing.
Safe way is:
Operate a 12v relay using the float switch and operate the pump using relay contacts so if the float switch leaks it will only leak 12v not 220v.
People say the float switch is safe but for personal preference and peace of mind I have used the above circuit.
clear explanation by graphics..
Thanks
What if the tank/well down where water it taken there is no more water? Will pump stops?
Great,instruction
Ovesly wonderful work
1.wonderful animation
2. Owesome voice and nice presentation
However this is not automatic control it is semi-automatic it does not put into consideration the water level of the well.
No schematic diagram. It is for common people.
Lovely .
Wonderful 🎉
what about photoelectric sensor ? its same way?
Woow just woow very useful
❤❤❤ thanks
Is this wired for 220V?
Working in the EU standard, (and the float switch seems to be made out in that standard as well - Brown for L1, black for L2/Com1, blue for neutral) it seems wrong to not follow those standards for the rest of the wiring as well. Without a wiring schematic for the float switch, I of course can only speculate how it's supposed to be wired, but it seems weird to connect the blue wire to phase and the black wire to neutral.
Totally wrong in the float find the common with meter common to one wire will show NO normally close and and normally open in the starter find the jumper green button and red button connected to the common to the jumper remove bottom of green button connected to start when tank level comes down to start when reaches stopped so even power shutdown this motor will start stopped automatically
@@michaelmanimani8483 On a complete side note, have you ever tried using proper punctuation?
It really helps make what you write readable. As it stands, I need a code key and an enigma machine to interpret what you've written, and I still risk a brain aneurysm it I were to try it.
Please advise the brand and model of contactor coil?
You can use schnider. Model no. Depends on current consumption
which software? Software name please
Thanks elot genesis
Please can you explain into details of the counter weight at 1:23
The weight holds down the float underwater. It sets the arc the float uses to turn on and off. If there was no weight, the float valve would stay at water level and would not act as an on/off switch.
My sump pump use a floating switch but only has two wires as a switch. It doesn't have three wires. Just out of curiosity can anyone use the floating switch on sump pump of the basement?
❤️❤️❤️
A circuit diagram would do wonders
Is it safe to have 220V going directly to the float switch?
No
what about the ground tank floating switch
Its automated so you wont need manual you can put a normal switch there or just pull down the breakers for it
Gret tutorial
In this video if u add a switch connection control it helps us who r new learner
timer realy ভিডিও দেখতে চাই , নতুন ভিডিও বানান
I need another explanation
👏💐🇮🇳
But AC dangerous to working with float switch, must to be DC low voltage
But the is no protection for the motor....
Motor pump green yellow black red blue pump green blue switch pink blue green teacher ji
l hd no ldea wt a float switch was
Ya nope, don't want AC flowing through my water tank
Dans
Teaching process is too fast
