Application of micro switch in home appliances|Air Purifier

The application of micro switch in air purifier

Before understanding the function of a micro switch in an air purifier, let’s see how the air purifier works.

We all know that air purifiers are a great way to improve the air quality in your home. They work by using filters to remove unwanted particles from the air. These filters can be made of different materials, such as activated charcoal or HEPA. The working principle of an air purifier is fairly simple. The device uses a filter that traps particles and then releases clean air back into the room.

The micro switch used in an air purifier is to realize the on/off situation of the circuit. When the button of the micro switch is triggered, the purifier starts to work; when the button is released, the purifier will power off and stop running running.

What is a micro switch?

micro switch structure

The micro switch is a tiny device that is made up of two metal contacts, a plunger, and a spring. When it is not being touched, the plunger rests on one contact. When the plunger moves to another contact, it completes an electrical circuit that activates something like a light or sound, or other devices. Although the micro switch has a small design, it is very sensitive to touch. From a certain perspective, micro switches are a type of sensor that detects changes in the environment and sends signals to other devices or systems based on those changes. Moreover, it is one of the most common electronic components. We can use micro switches in household appliances, electronic equipment, the automotive industry, power tools, etc.
