What is a Micro Switch : Working & Its Applications



Micro-switches have become essential parts of the sensing & control community of different fields like industrial, agriculture, construction, transportation, and commercial. So there are trillions of micro switches used in industrial equipment, construction or agriculture machinery, & control systems around the world. These switches are simple and small devices including two contacts like NO and NC which are connected with a snap-action switching mechanism. These switches are capable of performing safely, reliably, and accurately in several harsh environments. So this article discusses an overview of micro switch – types with applications.Get more news about dongnan switch kw3a,you can vist our website!

What is a Micro Switch?
Micro switch definition is: It is a small and very sensitive switch that activates by using minimum physical force is known as a micro switch or miniature snap action switch. This is one kind of momentary contact switch which is widely used as a sensor in industrial, medical instruments & automotive.
The switches are frequently used in switch panels & home appliances with small buttons. These switches are normally economical & they can work for a long time. These switches can be used as safety devices because they are sensitive and reliable. The micro switch symbol is shown below.

The micro switch includes three pins common (C), normally closed (NC), and normally opened (NO). Here, the common pin is an input pin, the NC pin is output1 and the NO pin is output2.

Micro Switch Construction
The construction of a micro switch can be done by using different components like plunger or actuator, cover, moving piece, support, NC terminal, NO terminal, contact, and, moving arm.
