What is a Float Switch?
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.

What can I use instead of a float switch?
The CheckPoint CP2-110 is an economical, reliable alternative to the traditional float-level switch. Because of its design, there will be no moving parts in the water to wear out, and the sensor probes will not foul, plate, or deteriorate, regardless of water quality.
What are the different types of float switches?
There are two types of float switches: stem-mounted float switches and cable-suspended float switches.
How long does a float switch last?
Most maintenance technicians expect them to fail two or three years into service. That’s why the Kari Float Switch is so awesome.
It can have up to four switch points in a single float, built-in hysteresis to handle the logic, and doesn’t need to be secured to conduit since you usually only need one.
Why do float switches fail?
Poor maintenance: A poorly maintained float switch can fail over time due to the debris that accumulates on its surface. Insufficient rating: A float switch has a rating to indicate the electrical load that it can handle.
How many amps does a float switch use?
The most common float switch rating is a 50-watt switch with maximum “do not exceed” parameters of 1 amp, 265 volts and 50 watts.
Do float switches need power?
Also known as liquid-level sensors, these products contain a hermetically sealed reed switch within a stem.
An external float, with a magnet inside, passes over and activates the reed switch as the liquid level moves up and down. This is shown in the below diagram. No power supply is required to operate these switches.
How accurate is a float switch?
When mounted vertically, this basic design provides a consistent accuracy of ±1/8 inch. Multi-station versions use a separate reed switch for each level point being monitored. Side-mounted units use different actuation methods because of their horizontal attitude.
What is the rule of floating switch?
The Rule float switch is robust durable and perfectly designed for controlling water pumps. When the water level is low the switch sits idle but as the water level increases the floating arm rises with the water and once the maximum level is reached the switch is activated.
