The micro switch is a type of switch that changes the direction of the current when your arm moves. You will learn about its technicality later. But first, let’s see where it is used. Micro switches are all around you. They are commonly used today.
Have you ever thought that when you open a refrigerator the light turns on and when you close, it turns off automatically? Is magic? Well, it is because of the micro switch that is installed in it. Every time you open and close it, the micro switch does that magic.
The same is similar to your car’s interior light. Micro switches have a variety of applications. Especially in the electronics industry, it is a revolutionary device that makes magic possible. Now the question is how that magic works. It’s where the technicality comes from.
A micro switch consists of three fixed terminals with a movable arm. These three terminals are generally known as C (common), N / O (normally open), N / C (normally closed). And due to its movable arm, which changes the direction of the current, it is also known as a Snap Action Switch. It is because it uses a spring to open and close the connection inside it.
There is a list of micro switches that are used for different purposes. It includes:
- Rocker switch
- ·Micro Switch
- Switch slide
- Door switch
- ·interruptor detection
- ·Interruptores limit
- ·Interruptor keyboard mechanical
- pressure switch
- ·interruptor rotary
- ·Interruptor active
Each of these switches has its own benefit of using it.
. Rocker Switch
Rocker switches are the most common type of switch used in electronic products such as computer power supplies, monitors, surge protectors, and many others. They consist of two indicator signs, that is, a circle for “ON” and a dashed line for “OFF”.
. Micro switch:
These switches are the magic switches used in washing machines, cars, refrigerators, doors, etc. They are used to detect the switching energy. It can detect the status of the doors whether they are open or closed.
. Slide switch:
A micro switch is called a slide switch when you use a slide arm to change the direction of the current. Remember that switch on your blue tooth headset. That is. Well, it is a small switch, there are switches larger than that with different slip points to change the current in multiple directions.
. Door switch:
As we have discussed the magic switch (Micro switch) They are used specifically on doors. They are used in closet doors to lighten, electric cabinet, refrigerators, car doors, microwave doors, etc.
. Detector Switch:
As the name suggests, the main purpose of a detector switch is to detect mechanical movement, that is, human operation, and convert it into electrical signals. Detector switches are a good alternative to encoders in some places to reduce costs.
An encoder is generally a type of position sensor. To determine the angular position of a rotating shaft, an encoder is used as in washing machines. Due to the rotational movement, it generates an electrical signal in digital or analog format.
. Limit Switches:
These switches are widely manufactured by China Micro Switch Manufacturer. They are used to count objects that pass through conveyor belts. Some other purposes for which it is used are as a safety interlock or as part of the control system used to control machinery.
. Mechanical keyboard switch:
I think you know that very well. For those of us who do not see what it is about. If you’re reading it on a PC, that keyboard of yours consists of these switches. Yes, all of its buttons consist of a dedicated mechanical switch dedicated to each key separately.
. Pressure Switch:
These switches are used in industries https://www.unionwells.com/ that deal with the flow of liquids or gases. It is established for a particular value of pressure of liquid or gas that passes through the pipe. When this pressure limit value is reached, the switch will automatically “ON” or “OFF” the electrical power. It is used strictly for security purposes.
. Rotary Switch –
You’ve seen these switches for a long time and played with them a lot. If you still have that old radio or music box of yours, you can easily recognize it. That big roller you have to manipulate frequency or volume is a rotary switch. Now also that fan regulator of yours is the same rotary switch.
Although micro switches have a wide range and infinite applications. But you must lose them carefully. To get the best micro switch, you can visit China Micro Switch Company.
