What is an industrial limit switch?

The limit switch, a type of position switch (also known as a travel switch), is a commonly used small current main electrical appliance. The collision of the production of mechanical moving parts makes its head contact to achieve the connection or breaking of the control circuit to achieve a certain control purpose.

What does a position switch do?

Limit switch is in industry, where it works 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 movement of the workpiece or the stroke of the automatic tool feed to avoid collisions. Sometimes the travel switch is used to automatically commutate the controlled object between the two specified positions, resulting in a continuous reciprocating motion. For example, when the automatic material transport car reaches the end point and touches the position switch, the overturning mechanism is connected, and the materials in the car are overturned out and returned to the starting point. After arriving at the starting point, I touched the limit switch of the starting point, connected the circuit of the charging mechanism, and began to load the car automatically. Always in this way, it has become a set of automatic production lines, without human management, working day and night, saving people's physical labor.
