Product Introduction ：

Travel limit switch, a position switch (also known as limit switch), is a commonly used small current main electrical appliances. Using the collision of the moving parts of the production machinery to make the contact action to realize the switch on or break the control circuit, to achieve a certain control purpose. Usually, this kind of switch is used to limit the position or stroke of the mechanical movement, so that the moving machinery according to a certain position or stroke automatically stop, reverse motion, variable speed motion or automatic round-trip motion.

Operating principle：

Stroke switch is the use of internal component collision, to achieve the function of opening or closing the circuit. Under normal circumstances, once the travel switch is opened, it will add a movement track to the mechanical movement. As long as the machine reaches the set position, it will automatically stop running or change the motion state.

Its working principle and structure are similar to buttons. Travel switch, also known as limit switch, is an automatic switch, is also the main commａnd of a kind of electrical appliances, usually travel switch is used to limit the position or travel of mechanical movement, so that the movement of machinery according to a certain position or travel to achieve automatic stop, reverse motion, variable speed movement or automatic round trip movement.

Function:

1. The travel switch mainly plays the role of chain protection in daily life. The most common examples are in washing machines and tape recorders.

In the process of washing machine dehydration (dry) speed is very high, if someone at this time due to failure to open the door of the washing machine or cover, after hａnd in again, it is easy to cause harm to people, in order to avoid this kind of accident, at the door of the washing machine or cover with the electric contact, once someone open the door of the washing machine or cover, automatically put the motor power, Even rely on mechanical linkage, so that the door or cover opened immediately "brake", forcing the rotating parts to stop, so as not to harm the person.

In recorders and VCRS, we often use fast forward or rewind, where the tape turns rapidly but stops automatically when it reaches its end. Here again the trip switch comes into play, but this time the action is caused not by a collision but by a sudden increase in the tension of the tape.

2, the stroke switch is mainly used in the industry to transfer the mechanical position into electrical signal, so that the running state of the motor can be changed, so as to control the mechanical action or used as a program control. It is combined with other equipment to form more complex automation equipment.

There are many such stroke switches on the machine tool, which can control the movement of the workpiece or the stroke of the automatic cutting tool to avoid collision accidents. Sometimes the travel switch is used to make the controlled object automatically reverse direction between two specified positions, so as to obtain continuous reciprocating motion. For example, when the car of automatic material transportation reaches the end point, it hits the trip switch, connects the overturned mechanism, and turns the material in the car out, and returns to the starting point. After reaching the starting point and touching the travel switch of the starting point, the circuit of the charging mechanism is connected, and the automatic loading is started. If it goes on like this, it becomes a set of automatic production lines, without human management, working day and night, saving the manual labor of people.
