What is the core principle of micro switch

There are many kinds of microswitches with hundreds of kinds of internal structures, which can be used in various occasions. Although the microswitches are small in size, they have important application value in the fields of electronics, instrumentation, aerospace, power systems, home appliances and so on. Many people may think that its design is very complicated, but its core principle is the same, so let's understand what is the core principle of the micro switch!

1, through the micro power to complete the disconnection or connection. When there is touch or sound in the outside world, the built-in mechanical force of the micro switch will be opened, and then the force transmission will be completed through its internal parts, so that the moving contact and the static contact can be quickly disconnected. On or on. Therefore, based on this concept, the sensitivity of the micro switch is also constantly improving.

2. When the force acting on the micro switch is continuously reduced, the corresponding reaction force will also become smaller. At this time, it is easier to complete some reaction actions, so as to accurately control the micro switch. Therefore, compared with traditional switches and microswitches, the advantages are all-round, which is why many electronic product and equipment manufacturers choose to use microswitches.

3. The stroke of the micro switch is very short, so its operation accuracy is very high. In the future, the standards will be higher. Only in this way, the quality and technology of the micro switch can be continuously improved, and can better serve the domestic manufacturing equipment.

The micro switch is small in size and large in effect, which can be seen everywhere in our daily life. Such as notebook mouse, car mouse, automotive electronic products, communication equipment, military products, testing instruments, natural gas water heater, gas water heater, gas stove, small household appliances, microwave oven heating, rice cooker, water pump pressure switch and other mechanical equipment supporting facilities, medical equipment, building intelligence, pneumatic tools, general electrical equipment and wireless mechanical equipment, 24-hour timer, etc.

Application of micro switch switch wiring

Generally speaking, the micro switch has three points. One is a common point, one is a switching point, and one is a closing point. A common point is like a neutral line in a power outlet. The switching point and the closing point are the points at which the power switch is turned on, facilitating the flow of current. The closing point is naturally the contact that breaks the current. Just connect the corresponding point to the corresponding part. Although the micro switch wiring method seems very simple, but still need to do the corresponding countermeasures in advance. When buying a micro switch, we have to consider a variety of factors to measure. Such as the size of the manufacturer, quality, after-sales and other factors.
