What kind of switch is the metal key switch and what needs to be known? Today we will give you a detailed introduction.
This article will introduce some contents about metal key switches, including the introduction, construction, performance, classification and other details of metal key switches.
Let's first understand what a metal key switch is and what its brief introduction is.
Metal push-button switch refers to the switch that uses the button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. Metal button switch is a simple and widely used master electric appliance. In the electric automatic control circuit, it is used to manually send out control signals to control contactors, relays, electromagnetic starters, etc.
With the rapid development of microelectronics technology, control technology is becoming more and more perfect and mature. As the core component of industrial control, metal button switch has more and more powerful control function, smaller and smaller size, and more and more reliable operation. Human-machine interface (HMI) has completely broken the traditional operation mode of button, signal lamp and so on. The equipment operation interface is more popular, friendly, flexible and diverse, and its powerful storage function and communication ability bring unthinkable benefits and convenience to the manufacture and users of equipment. It is a general trend to replace the traditional equipment operation interface. At present, the frequency converter used for ordinary motor speed regulation has far exceeded its control technology. Early single metal button switch control mode developed rapidly toward sensorless vectorization and direct distance control, which made it widely used in all walks of life.
Metal button switches are also widely used, but they are second only to light touch button switches. In some large machine tools or elevators and other mechanical and electrical appliances, they are used more frequently. Due to the corrosion resistance of metal button switch, the dust and water proof effect is very good, and the metal key cap, as well as the internal structure of the switch lead to its long service life.
The main supporting fields of metal button switch with lamp are electronic control equipment, lifting equipment, heavy machine tool equipment, power electronic equipment, transportation vehicle, aerospace, ship, household appliances, etc.
