The micro-switch is a switch that operates rapidly with a very small amount of force. The micro-switch is also called a miniature snap-action switch. It is extremely reliable, fast, and efficient to operate, and is also known as a miniature snap-action switch. It is impossible to create smart appliances without micro switches. They are used in many modern-day smart applications. Microswitches are often used as safety devices because of their reliability and sensitivity. They are used to prevent the closing of doors when something or someone is in the way and other similar applications.Get more news about dongnan switch kw3a,you can vist our website!

The micro switch has three pins: Common (C), Normally Closing (NC), and Normally Opening (NO). Here, the Common pin is an input pin, the NC pin is Output 1, and the NO pin is Output 2.

With its tiny contact gap, The micro switch is a snap-action precision switch for logic-level and power-duty loads. The switch has options like SPDT, SPNO, or SPNC, and offers power-duty switching through silver alloy contacts. Different electrical terminations are available, and logic-level control can be achieved by silver alloy or gold-plated contacts. How Does a Micro Switch Work? A micro switch is equipped with an actuator that lifts a lever when pressed to move the contacts into the proper position when depressed. When pressed, micro switches often make a “clicking” sound. Often, micro switches have mounting holes so they can be quickly mounted and secured into place. Due to their long life, they rarely need to be replaced and require little maintenance since they are such a simple switch.

The working principle of a micro switch is that when it touches an object, the contacts change position. Thus, the principle of operation of this switch is mainly as follows.

The normally closed pin of the circuit is opened and the normally open pin is closed when you press the lever of the switch. In the same way, when you open the lever of the switch, then the normally closed or NC pin of the circuit will carry the current, while the normally open or NO pin of the circuit can isolate electrically.

The tipping point mechanism is also the basic feature of the micro switch. So, this feature will help to generate certain tripping points and reset points wherever the contacts will change the state. Micro Switch Circuit Following is the circuit diagram for the micro switch. The circuit shown below uses a micro switch to control two LEDs with a battery. The micro switch has three terminals, which are C, NO, and NC. This circuit can be connected in the same way as the circuit shown below. There is no connection between the NO terminal and the common terminal of the switch when the lever is pressed. Therefore, the Green color will turn on once the lever is pressed.

After the lever has been raised, the common terminal and the NC terminal of the switch will be connected, so the NC terminal of the switch will not be connected, consequently the Blue color LED will turn on. Based on the application, we can use the switch in NO or NC mode.
