Once we mention limit switches, I believe we all probably know what limit switches are. With the development of science and technology, limit switches play an increasingly important role in our lives. So, what is the specific performance of limit switches? The next specific introduction for everyone, I hope you have gained Oh.
First, the role of limit switches - protection
The most important role of the limit switch must be its protection effect, limit switch is also known as the travel limit switch, mainly used to control mechanical equipment travel and limit protection. In practice, the travel limit switch is installed in a prearranged location, and when installed in the production machinery moving parts module hitting the stroke, the travel limit switch contacts act to effectively realize the switch between circuits.

Limit switch refers to a kind of circuit electrical apparatus that switches correctly according to the travel position of the moving parts, and the function principle of the limit switch is similar to the button. Widely used in all kinds of machine color aluminum doors and windows, lifting machinery, etc. to control their travel and terminal limit protection.
Second, the role of limit switches - daily life
With the continuous progress of society, electrical equipment is used in our daily life in large quantities, in many electrical equipment are inseparable from the use of limit switches, then what is the role of limit switches? The most important role of the limit switch is to chain protection of machinery.
There is nothing more common in life than limit switches in washing machines, tape recorders applications. When the washing machine dehydration in the speed is very high, if due to negligence to open the washing machine or cover after the hand into, very easy to cause injury to the human body, in order to effectively avoid such accidents, most washing machines are installed with electrical contacts, once the washing machine door or cover is opened, it will automatically power off, forcing the rotating parts to stop, effectively avoiding the occurrence of injury.
Third, the role of limit switches - industrial
The role of limit switch is also shown in the industrial field, mainly used to transform the mechanical displacement into electrical signals, so that the motor operating state can be effectively changed to control mechanical action or program control. The real use of limit switches is in industry, where they are used in conjunction with other equipment to form more complex and scientific automation equipment.
Limit switches on machine tools effectively control the movement of the workpiece and the automatic tool feed stroke to avoid collisions. The use of limit switches allows the controlled object to change direction automatically between the specified positions and get a constant reciprocating motion.
