What is a microswitch?

A micro switch is a small contact interval and fast-moving mechanism, with the specified stroke and the specified force of the switch action contact mechanism, covered by the shell, its external drive rod of a switch, because the switch contact spacing is relatively small, so the name of a micro switch, also called a sensitive switch.

A micro switch is a mechanical electronic component, also known as a micro trigger switch or limit switch. It usually consists of a spring, a moving contact, a static contact, and an adjustable firing pin. Microswitches are widely used in industrial control and home appliances.

What are the applications of the microswitch?

In household appliances, a micro switch is widely used in washing machines, air conditioning, refrigerator, oven, microwave oven, electric ovens, water dispensers, and other household appliances. In these household appliances, the micro switch can detect and control the linkage of various parts, so as to realize automatic control, improve production efficiency and ensure production safety. For example, the door lock in the refrigerator is realized through the micro switch, when the refrigerator door is closed, the micro switch contacts merge, and the circuit forms a closed state, telling the system that the door has been closed; The door lock of an electric oven is also used with micro switch technology, which can ensure that the door is close to the main body and avoid the hot gas interference between the oven and the baking pan, affecting the normal use.

Microswitches in industrial control are widely used in machine tools, automatic assembly lines, automatic measuring equipment, material handling machinery, processing equipment, and other fields. In this mechanical equipment, a microswitch can realize the control and monitoring of its circuit or mechanical structure. For example, a micro switch on a conveyor can detect the position, speed, and stop status of a moving item; When the object on the conveyor belt reaches the micro switch, the switch is triggered, and the notification system controls the conveyor belt and the mechanical automatic processing behind it. Microswitches are also widely used in smart devices such as robots and drones. In the UAV, the flight distance can be controlled by installing microswitches beside the steering gear and motor to ensure the stable flight of the UAV.

Microswitch is a very common and very important electromechanical component. Its appearance makes the automatic control of various mechanical equipment more simple and reliable. Through continuous in-depth research and technological innovation, the performance of microswitches has been improved, which provides important support for modern production and intelligent control.
