1. The function of the spring in the travel switch is a kind of sensor, which is mainly used to detect and control the position, status or action of electromechanical equipment during operation, and to control the operation state of electrical appliances by judging the output signal of the travel switch. The spring in the travel switch is an important component, which plays the following two roles.
1. Protect electrical appliances.
One of the main functions of the springs in the travel switch is to protect the electrical appliance. In the process of using electrical appliances, due to external reasons or the reasons of the electrical appliances themselves, sometimes there will be overcurrent or overvoltage. At this time, the spring can play a buffering role, by adjusting the position of the electrical appliance, so that the electrical appliance can avoid being damaged in the case of overcurrent or overvoltage, so as to protect the safe use of the electrical appliance. 2. Control electrical appliances.
Another major role of the springs in the travel switch is to control the electrical appliance. In the process of using electromechanical equipment, it is often necessary to control the operating status of electrical appliances according to different needs. In this process, the spring in the travel switch can control the operation status of the electrical appliance by adjusting the position of the electrical appliance and outputting the corresponding signal, so as to realize the operation of the electromechanical equipment according to the predetermined program. Second, the principle of the spring in the travel switch.
The principle of action of the spring in the travel switch is actually very simple, it plays the role of protecting and controlling the appliance by using elastic deformation. When there is a problem with the external environment or the electromechanical equipment itself, the spring in the travel switch will undergo corresponding elastic deformation and be conducted to the travel switch, so as to control the operation and stop of the electrical appliance. In addition, the springs in the travel switch are usually coordinated with other components through the mechanical structure to complete the work. In the process of normal use, the spring in the travel switch needs to be maintained and replaced periodically to ensure its reliability and service life. To sum up, the spring in the travel switch is an important element in the travel switch, which not only plays the role of protecting electrical appliances, but also realizes the automatic control of electromechanical equipment by controlling electrical appliances. Therefore, it is necessary for manufacturers and users of electromechanical equipment to strengthen the research and maintenance of the springs in the travel switches.
