Wall switch as people focus on the home environment becomes more than a variety of lighting 1. Switch: several switches side by side, each controlling their own lights. Often said: double, triple, or an open, four open and so on. 2. The dual-control switch: the two switches in different locations can be controlled in the same light, as explained in the stairs, halls, bed and so on, to be pre-wired. 3. Luminous switch: fluorescent lights or dim light wall switch board with the switch, easy to find location at night. Special note: The disadvantage is that such a switch: a light switch is more expensive, and fluorescent lamps, ceiling lamps when used in conjunction with, there will be lights flicker; b fluorescence by reflected light, a few years later is darker... 4. dimmer switch: You can switch and light intensity can be adjusted by the knob. Note: Can not be used in conjunction with energy-saving lamps. Above Hebei Extension of communication Power Equipment Manufacturing Co., Ltd. to offer hope to the industry to help a friend. Constitute principles switch socket: If you want to switch socket reasonable and scientific improvements wall switch 118, will be carried out some research constitute their principle and works, the only way to design a socket to be able to meet people's needs. Next, I to multifunction smart socket for example, described some of the principles of its constitution, and how it works. Constituting multi-socket module mainly consists of a microcontroller system, the state detection module and power module configuration. Specific structure as shown below: switch socket detection module typically includes current sensing, temperature sensing and voltage detecting these parts. Through the observation of the figure, we can also learn to control core of the system is a single chip, it is through the keyboard input value and each corresponding detection signal processing, so that the LCD displays the results, through the relays socket Open and disconnect function. led wall switch | wall switch | Vicki appliances provided by the Hebei Tianyi Electric Co.
