ZJSHUYI Can the travel switch reset automatically?

Share This Post

The #travelswitch is also called the limit switch. In the travel control of the electromechanical equipment, its action does not require human operation. The main purpose is to use the collision or induction of some moving parts of the production machinery to make its contacts move, and issue control commands to achieve near and far. Distance travel control and limit protection.

The main structure of the #travelswitch is generally composed of three parts: the operating mechanism, the contact system and the shell: according to its structure, it can be divided into direct-acting type, roller type and micro-moving type; according to its reset method, it can be divided into automatic and non-automatic reset; Its contact properties can be divided into contact type and non-contact type. In order to be suitable for different working environments, the travel switch can be made into a variety of structural shapes

In actual production, there is also a non-mechanical contact switch called a proximity switch, which has the function of a travel switch. Its action principle is that when an object approaches a certain distance from the switch, an “action” signal is issued, and no mechanical external force is required. Proximity switches can be widely used in product technology, speed measurement, liquid level control, metal detection and other fields.

Because proximity switches have the advantages of small size, high reliability, long service life, fast action speed, no mechanical collision, no electrical wear, etc., they have been widely used in automatic control systems of electromechanical equipment. Various structural shapes of proximity switches

The #travelswitch is generally reset by itself. Its function is to turn on or off when the object presses the switch to make the switch move to a certain extent. When the object leaves the switch, the travel will automatically rebound and reset. Except for a few parts that require manual reset,

The reason why the travel switch does not reset:

1. Too much overtravel of moving parts or collision block, mechanical failure, switch collision block,

2. Impurities enter the inside of the switch, causing the mechanical part to be stuck,

3. The return spring of the switch fails, and the elastic force is insufficient so that the contacts cannot be reset and closed
