Metal push-button switch refers to a switch that uses a button to push the transmission mechanism to connect or disconnect the moving contact and the static contact and realize circuit switching. The metal button switch is a main electrical appliance with simple structure and wide application. In electrical automatic control circuits, it is used to manually send 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 push button switches have increasingly stronger control functions, smaller and smaller sizes, and faster and more reliable operation. The human-machine interface (HMI) has completely broken the traditional button, signal light and other operating modes, making the equipment operation interface more user-friendly, flexible and diverse, and its powerful storage function and communication capabilities have brought unimaginable benefits and convenience to equipment manufacturers and users. It is a general trend to replace the traditional equipment operation interface; the control technology of the frequency converter currently used for ordinary motor speed regulation has far exceeded the early single metal button switch control method, and is rapidly developing in the direction of sensorless vectoring, direct torque control, etc., making it widely used in all walks of life.
The application range of metal button switches is also very wide, but second only to the touch button switches, they are more commonly used in some large machine tools or daily elevators and other mechanical appliances. Due to the corrosion resistance of metal button switches, they are very dustproof and waterproof, and their metal keycaps and internal structure of the switch also have a long service life.
The main supporting fields of illuminated metal button switches are electronic control equipment, lifting equipment, heavy machine tool equipment, power electronic equipment, transportation vehicles, aerospace, ships, household appliances, etc.
