Float switch installation requires you to mount the device with some way of fixing the cable above the tank or well. There is a mounting bracket available for the Kari Float Switch that uses a snug wedge to fix the cable into place. This bracket can be attached to a wall or a rail using a simple bolt or screw.

How to install a float switch for a pump?
We can help you calculate how much liquid level you’ll need to satisfy your pump’s requirements. Float switch installation requires you to mount the device with some way of fixing the cable above the tank or well. There is a mounting bracket available for the Kari Float Switch that uses a snug wedge to fix the cable into place.
How do you connect a float switch to a 3 way switch?
The powered wire from the manual switch is connected with the line terminal of the 3-way switch. Connect the bilge pump wire to the switched terminals of the 3-way switch. Now connect the float switch by connecting a wire to each switched terminal on the 3-way switch.
How do I install a float switch on my waterproof enclosure?
Once you’ve figured out the weight position and your switching levels, you’ll need to install float switch wiring to your waterproof enclosure. Make sure you seal the cable entrance with a cable gland. For wiring instructions, refer to the user manual, or our new float switch wiring guide.
How do you hook up a float to a well?
Once you have figured out your switch points, use a clip or a mounting bracket to secure the cable above the well or tank, with the bottom of the float hanging at the exact position needed (ground zero). Depending on your Kari model, wire up the cable to the appropriate terminals in your control panel box.
How do float switches work?
Let’s start with the most basic float switch: a two-wire, single-pole, single-throw float switch. The rising action of the float can either close (i.e., turn on) a “Normally Open” circuit, or it can open (turn off) a “Normally Closed” circuit. Installation scenarios might include a Normally Open float switch turning on a pump to empty a tank (Control Schematic 2), or a Normally Closed float switch turning off a pump that fills a tank (Control Schematic 1). In both schematics, terminal 1 in the control circuitry represents the landing point for the float switch’s (+) wire, and terminal 2 for the (-) wire.
What can you do with a Kari float switch?
Since that was so easy, let’s take a look at what you can do with a three-wire KARI series float switch: add an alarm signal! Instead of four wires for simple, two-level hysteresis, a KARI series 3H float switch gives you two-level hysteresis and an alarm using just three wires.
What happens when a Kari float tilts?
As the single KARI series float rises with the liquid level in the tank, it tilts to one side. The microswitches inside the float activate at factory-set angles as the float tilts, and the preprogrammed control circuitry responds accordingly.
How many wires are in a Kari float switch?
That’s right. With a KARI series 2L float switch, you get the same hysteresis control using one switch and two wires instead of two switched and four or six wires. “What is this Magic,” you ask? Simple: each KARI series float switch has multiple microswitches and control circuitry built into the float.
What level of liquid must be in a tank before a motor starts?
In fact, the liquid level in the tank must fall below low-level switch L before the motor will start. At that point, both the low-level and high-level switches will be closed, completing the circuit, and activating motor relay P to start the pump.
What happens when the liquid is below the switch?
When the liquid is below both switches, they are both closed; the pump runs, filling the tank. As the liquid fills past the first switch, it opens. However, seal-in relay A has been activated and closed, bypassing the now-open switch L (effectively “sealing it in”), so the pump continues to run until the high-level switch H opens. When the high-level switch opens, the motor relay P opens, stopping the motor, and seal-in relay A opens.
How much inrush current is needed for a motor starter?
For larger motors, inrush current (up to six or eight times full load current) becomes an important factor in the starting and maintenance of the motor, rendering contactors insufficient as stand-alone motor starters. Such motors need integrated controllers and overload protection in order to start safely and still be protected while running at full load. Fortunately, most motors of this size will either be controlled via a motor control center (MCC) or a dedicated control panel, both of which are fully capable of integrating control circuits and instruments like those shown above.
What is a float switch for a boat?
A bilge pump float switch turns the bilge pump on automatically when the water passes a certain level in the boat. Here are a few instructions on how to install a bilge pump float switch.
What position should a float switch be?
The float switch should be sitting equal with the bilge pump or slightly higher. The float switch sits in this position so that the bilge pump isn't activated until the water level reaches the pump.
How to change a float switch on a bilge pump?
First, connect the negative cable back onto the battery. Flick the switch on the 3-way switch to off. You shouldn't hear anything from the bilge pump. Position the switch to automatic and again the bilge pump should be off. The bilge pump should start working when the switch is in the manual position. Flip the 3-way switch to automatic again and fill the bilge with some water. As soon as the water level is passed, the float switch and the bilge pump should start to empty the water from the bilge. You now have completed the installation of the bilge pump float switch.
How to replace a manual bilge pump switch?
The powered wire from the manual switch is connected with the line terminal of the 3-way switch. Connect the bilge pump wire to the switched terminals of the 3-way switch. Now connect the float switch by connecting a wire to each switched terminal on the 3-way switch.
Can a float switch be used with a bilge pump?
When you buy your bilge pump float switch be sure that it is compatible with the bilge pump on your boat. A lot of bilge pumps will run on a 12V DC power and it is very important that your float switch is intended for the use of 12V power. Also be certain that the switch is rated slightly higher than the bilge pump's wattage draw.
Can you run a bilge pump wire through a switch?
When you are running the wires, try using an area that is out the way. Many people choose to run the wire through the bilge. Nonetheless, if you do it this way be sure to avoid running the wire where it will be continuously wet.
How to connect a float to a float?
Here is a simple step-by-step: 1 Attach float to mount inside dosing container. 2 Route the cable out from the top of the dosing container. 3 Connect wire leads to controller or other device.
What is a horizontal float switch?
Horizontal Float Switch: Commonly used to top off water, this type of float switch is usually attached directly to the line that supplies the top-off water. As the liquid level in the aquarium or sump decreases, the float opens and allows top-off water to enter the system.
What type of float switch is used in aquariums?
Here are the most common types of float switches used for aquariums today: Vertical Float Switch: This type of float switch is both simple to use and very reliable, since the float can only move upward and downward. It is commonly used for automatically topping off liquids in a dosing container or RO water in the sump.
What is a Float Switch?
A float switch is a device that identifies the level of fluid in a container of a tank. Therefore, it is also known as a water level controller. Nevertheless, it hangs at the topmost of the water surface. Additionally, a float switch behaves like a mechanical switch when the liquid level rises or goes down.
How Does a Float Switch Work?
The primary function of float switches is to close and open the circuit. Moreover, this happens when the level of the liquid goes up or down. Although, most of the float switches are closed since they have two cables running from the top of the device to complete the circuit.
How do You make a Float Switch at Home?
Making a float switch circuit board is very simple. Therefore, below are the materials you need and the procedure. Moreover, make sure you try to make a good quality float switch to serve you to the maximum.
Summary
Having read through the article, I believe you have the information about everything you should know about the float switches circuit. Additionally, it would be best to get the correct float circuit for your application to avoid failure. Nevertheless, feel free to visit us for more information.
