1. Protection

The most important role of the limit switch must be its protection effect, the limit switch is also known as the travel limit switch, which is mainly used to control the stroke of mechanical equipment and limit protection. In practical application, the stroke limit switch is installed in a pre-arranged position, and when it is installed in the production of mechanical moving parts module impact stroke, the stroke limit switch contact action to effectively switch between circuits.

Limit switch refers to a kind of circuit electrical appliance that correctly switches according to the travel position of moving parts, and the principle of action of the limit switch is similar to that of a button. It is widely used in all kinds of machine color aluminum doors and windows, lifting machinery, etc., to control their travel and terminal limit protection.

2. Daily life

With the continuous progress of society, electrical equipment is widely used in our daily life, and many electrical equipment are inseparable from the use of limit switches, so what is the role of limit switches? The most important function of the limit switch is to interlock the machinery.

The most common thing in life is that the limit switch is applied in washing machines and tape recorders. When the washing machine is dehydrated, the speed is very high, if the washing machine or cover is opened due to negligence, the hand is put in, it is easy to cause harm to the human body, in order to effectively avoid this kind of accident, most washing machines are installed with electrical contacts, once the washing machine door or cover is opened, it will automatically cut off the power, force the rotating parts to stop, and effectively avoid the occurrence of injury.

3. Industry

The role of the limit switch is also manifested in the industrial field, which is mainly used to convert the mechanical displacement into an electrical signal, so that the operating state of the motor can be effectively changed to control mechanical actions or program control. The real role of the limit switch is in the industry, and other equipment to form a more complex and scientific automation equipment.

The limit switch on the machine tool effectively controls the movement of the workpiece and the automatic feed stroke to avoid collision accidents. The limit switch is used to make the controlled object automatically reversible between the specified positions, and the continuous reciprocating motion is obtained.
