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.

Principle of Dimming Switch

A dimmer switch is an electronic device that intelligently changes lighting, and the brightness can be gradually adjusted from almost no light to maximum brightness through a knob or slider. Dimming switch controls the voltage of the lamp by adjusting the resistance value inside it. Its basic principle is to change the voltage applied to the load, which is accomplished by single or bidirectional thyristor. By manually adjusting the potentiometer to change the phase angle applied to the control stage, the conduction degree of the thyristor is controlled, which completes the purpose of changing the voltage.

Advantages of Dimming Switch Products

1. The appearance is exquisite, the craftsmanship is meticulous, and the colors and patterns can be customized according to user preferences.

2. The backlight effect points you in the direction of progress in the dark, practical and thoughtful.

3. Each switch button of the dimmer switch fully meets the corresponding light source of 5-00 watts.

4. Each switch button with a super large capacity can store 20 key values of the controller.

5. The dimming switch has diverse control methods, which can achieve touch control, on-site remote control, and remote control.

Dimming switch usage safety warning

Before installation and disassembly, please make sure to cut off the main power supply.

2. Before installation, ensure that the circuit is not short circuited or connected incorrectly.

3. When installing and using dimmer switches, attention should be paid to waterproofing, steam resistance, and impact resistance.

4. Do not use sharp objects to scratch the touch panel.

5. Do not use excessive force when turning on or off the dimmer switch to avoid crushing the touch panel.

6. When cleaning, please use a dry cloth for wiping, and do not wipe with damp or corrosive substances. Otherwise, there is a risk of electric shock and corrosion damage to product components.

7. It is strictly prohibited to use the dimmer switch under overload, otherwise it may cause heating, burning or fire.

Application of Dimming Switch Requirements

Dimming switches can meet people's different needs for lighting brightness at different times and can directly replace existing wall switches. Suitable for public places such as family rooms, apartments, hotels, hospitals, etc. With the improvement of living standards, people cannot do without light, let alone the demand for the quality of light. The demand for dimming can be roughly divided into three categories:

1. The need for functional adjustment of lighting, such as the entrance foyer, conference room, etc;

2. The embodiment of comfort and lifestyle style in home life, such as lighting
