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...

[michaelankrah]

Your videos are of high quality standards and every detail comes with the understanding I have been searching for I can wait for forward and reverse as well as Star delta wiring

[unclecraigbaannawk]

watched 20 vids on this topic...this is the first one i can understand...lol great graphics!

[heinminnthant]

the explaining was so good but can i get a diagram for this control?

[kingcesar]

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!

[douglaselectricalandinteri]

Its simple, and that is actually its done.

[subramaniamasokan]

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

[uffetembo]

Thank you so much… going to instal one tomorrow in Libala

Best video on how to connect float switch using contactor ❤❤

[manuellastrollo]

great video. super easy to understand. hope to see more

[tjaartduplessis]

thank you for easy understanding the wiring diagram

[elvinesotieno]

Indeed it a wonderful video. If provide me with the refrigerator repair techniques too brother. You are really good at Electrical

[MrJonsi]

What modelling software are you using?? So clean and simple!

[ramborums]

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?

[jameslue-a-king]

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...

[simontsegay]

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.

[danielteyehuago]

Wow! This is very educative and thanks for sharing it with us...

[ArmanIBae]

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!

[SmokeyRidgeTrader]

awesome video and very helpful thank you💯
