The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism, and a contact mechanism that performs the switching action with a specified stroke and a specified force. Small, hence the name micro switch, also called sensitive switch, snap switch. Pressure actuated quick switch. For door switches in anti-theft systems, etc.
The external mechanical force acts on the action reed through transmission elements (pressing pins, buttons, levers, rollers, etc.) point to switch on or off quickly.
When the force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously.
The contact distance of the micro switch is small, the action stroke is short, the pressing power is small, and the on-off is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element.
Notes on the use of microswitches< /strong>
1. Pay attention to the environment where the micro switch is placed
If we place the power switch in a room containing corrosive gas, some electronic components in these electronic products are easily corroded, which will seriously affect the life of the entire electronic product. If the environment near our electronic products is too humid, it is easy to cause some electronic components to rust, the entire circuit board to be in series, and even the entire electronic equipment to be damaged by leakage.
2. Prevent foreign objects from entering.
For example, if some common indoor animals such as cockroaches, geckos, and spiders enter these power switch components, these animals themselves, like the human body, are objects that are easily conductive, and it is very easy for the entire circuit board to be disordered, resulting in the failure of the entire electrical appliance. Not a very rare case of many electrical failures.
3. Don't be too violent when using it.
The micro switches of electronic products are generally relatively small, and the internal structure is very precise. If the user uses too much force, it is easy to damage the precise structure. In addition, the switch cannot be pressed all the time. Such behavior will easily cause them to appear. Failure, the switch response is not sensitive enough in the future use.
Since the micro switch appeared on the market, it has been applied to many electronic product fields at a very fast speed, such as digital products, home appliances, medical equipment, toy products, etc. It has become a very common electronic component in our daily electronic products. , then, when we use this type of electronic components, we should pay attention to the three points planned by Ogo Electronics to improve the switch life.
