You may be unfamiliar with the float switch, which is normal, because its name is too specialized, but it exists in our daily life and plays an indelible role. Today I will introduce you to the float switch. The working principle and magical effect of the ball switch
1. What is a float switch?
The float switch is a special kind of switch, because it does not require power supply. It is a pressure switch with a very simple structure. It is small in size, made of stainless steel or plastic, and has a long working life. It has been widely used in water treatment.
2.How the float switch works
The float switch does not need a power supply, its power is the magnetic force, and no additional mechanical connecting parts are needed. Its structure is a float, a main body and a magnet. When the measured object of the float switch floats the float, the float will start to move under the influence of buoyancy, and the main body will also move up. At this time, the magnet at the other end will control the switching action of the main body rod. This is the general working principle of the float switch. I think everyone will find it difficult to understand after reading it. This is normal, because this switch is an internal switch and is included in home appliances. There are not many opportunities for us to see it. Take the water heater and water dispenser as an example. When the water in the reservoir is empty, they will perform a pumping activity. Then the floating ball switch controls the pumping activity. It can accurately identify the water level and ensure timely pumping. Make sure the appliance is not burnt out. In this way, is it easy to understand?
3.The role of the float switch
The advantage of the float switch is that it can accurately measure the water level of the liquid, so it is generally used in the liquid detection of atmospheric or pressurized liquid storage tanks for signal transmission, such as liquid level alarms, which is very applicable. powerful. It can accept multi-point control, and its use location can also be determined by the customer. It does not need a power supply to ensure its environmental protection. Its lifespan is about 2 million times of switching. Whether it is the price of the product itself or the installation cost, it is very affordable and cost-effective. The protection level is very high, it can work under high temperature or high pressure conditions, and it has high safety, so you can use it with confidence.
