The travel switch is an electrical switch that converts mechanical signals into electrical signals, and is used to convert the transmission of mechanical action information. The main components of the travel switch are micro switch, return spring shaft, striker, lever and roller.
The composition of the travel switch includes a reaction force system. The travel switch is a kind of position switch (also known as limit switch), which is a commonly used low-current master electrical appliance. It uses the collision of the production mechanical moving parts to make the contacts move to make or break the control circuit to achieve a certain For the purpose of control, usually, this type of switch is used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse movement, variable speed movement or automatic round-trip movement according to a certain position or stroke.
The travel switch is mainly used to convert the mechanical displacement into an electrical signal, so that the running state of the motor can be changed, so as to control the mechanical action or be used for program control. There are many such travel switches on the machine tool, which are used to control the movement of the workpiece or the automatic feed Stroke, avoid collision accidents, use the travel switch to automatically reverse the direction of the controlled object between the two specified positions, so as to obtain continuous reciprocating motion.
The process switch is mainly used to convert the mechanical displacement into an electrical signal, so that the running state of the motor can be changed, so as to control the mechanical action or be used for program control.
The real use of the travel switch is in industry, where it cooperates with other equipment to form more complex automation equipment.
There are many such travel switches on the machine tool, which are used to control the travel of the workpiece movement or automatic tool feed to avoid collision accidents. Sometimes the travel switch is used to automatically reverse the direction of the controlled object between the two specified positions, so as to obtain continuous reciprocating motion. For example, when the trolley that automatically transports the material reaches the end, it touches the travel switch and turns on the overturning mechanism, and the material in the car is turned over and returned to the starting point. After reaching the starting point, it touches the travel switch at the starting point, turns on the circuit of the loading mechanism, and starts automatic loading. If it goes on like this, it becomes an automatic production line, which does not need human supervision, and works around the clock, saving people’s manual labor.
