What is the principle of a dimmer switch? What are the characteristics?
Wall switches are commonly used in daily life, but as people's needs become increasingly diverse, various shades of light have emerged. As a result, dimmer switches have emerged, which can be gradually adjusted from almost no light to maximum brightness through knobs or sliders. The electronic dimming switch controls the degree of conduction by controlling and changing the phase angle of the thyristor, that is, the time when the power flows through the load. This changes the input voltage and current of the light source to obtain different intensities of light output. Using a single live wire input wiring method, it can directly replace existing wall switches.

Precautions for selecting microswitches
In military and civilian wireless equipment and automatic control equipment in production processes, various types of microswitches and other connectors are often needed to achieve manual or automatic circuit switching, connection or disconnection control, and to replace various complex circuits with a few circuits. With the development of science and technology, as well as the different requirements for installation, operation control, aesthetics, and reliable performance, the strict requirements for military equipment have led to an increasing variety of switch specifications.
The trend of micro switches
With the continuous development of China's economy and the continuous improvement of people's living standards, people's consumption concepts and levels have also undergone significant changes and improvements. Under this opportunity, the micro switch industry has also experienced rapid development. In 2018, the market size of China's micro switch industry increased year-on-year compared to 2017. From the development of market size in the past two years, it can be seen that the micro switch industry is in the process of development and is expected to maintain growth in 2019.
What do you know about the classification of microswitches?
In our daily lives, there are many different types of switches that we often see, but we may not necessarily understand. Next, we will introduce to you the classification of common switches? Microswitch
Introduction to microswitches, working reasons and loss measures
A microswitch is a type of switch that has a small contact spacing and a quick action mechanism, and uses a specified stroke and force to perform the switch action. It is covered by a casing and has a driving rod on the outside. Because the contact spacing between its switches is relatively small, it is called a microswitch, also known as a sensitive switch. The electrical text symbol is SM.
