Wall switch knowledge information
Common terms for switch sockets:
1. Multiple switches: Several switches are arranged in parallel, each controlling its own light. Often also called: double, triple, or one open, four open, etc. 2. Dual control switch: Two switches can control the same light in different positions, such as at the stairway, lobby, bedside, etc., which need to be wired in advance.
3. Luminous switch: The switch is equipped with a fluorescent or low-light indicator, which is convenient for finding the location at night. Special reminder: The disadvantages of this type of switch are: a. Illuminated switches are more expensive, and when used in conjunction with fluorescent lamps and ceiling lamps, the lights will flicker; b. Fluorescence depends on reflected light and will be darker in a few years.
4. dimmer switch: It can be switched and the intensity of the light can be adjusted through the knob. Note: Cannot be used with energy-saving lamps.
5. 10A: Meet the electricity quota for ordinary electrical appliances in the household.
6. 16A: Meet the requirements of household air conditioners or other high-power electrical appliances (water heaters). Note: The plug specifications of the electrical appliances you use.
7. Socket with switch: it can control the socket on and off; it can also be used as a switch alone. It is mostly used in common electrical appliances, such as microwave ovens, washing machines, air conditioners, etc., as well as individual control of mirror lights.
8. Frame and panel: assembled switch socket, color can be changed, easy to disassemble and free in style.
9. Blank panel: used to seal the check box reserved on the wall, or abandoned wall holes.
10. Cassette: Installed in the wall, pre-buried before wiring.
11. 146 type: twice the width of ordinary switch sockets, such as some four-position switches, ten-hole sockets, etc. Note: The long cassette can only be installed.
12. Multi-function socket: compatible with old-fashioned and foreign standard round-pin plugs, square-pin plugs, etc.
13. Conversion socket: Chinese standard electrical appliances adopt the national standard. If you go abroad to use, you need to go through the socket conversion and some voltage conversion.
14. Special switches: remote control switches, sound and light control switches, remote sensing switches, etc.
15. Information socket: refers to telephone, computer, TV socket. The plug-in modules on the back end are expensive because of the high market prices of genuine products. Note: Most of the fakes on the market are genuine when the power module is genuine, and the information socket is fake. This is where the huge profits come from.
16. Broadband TV socket: (5-1000MHZ) adapt to the high-frequency cable TV signal of individual communities, it has nothing to do with digital TV.
17. TV-FM socket: The function is the same as the TV socket, and the function of listening to FM radio is rarely used.
18. Tandem
TV socket: behind the TV socket panel with one or more TV signal distributors. Note: Depending on the electrical wiring, it is also called one-to-two, or one-to-three, one-to-four, etc. In addition, there are non-panel type distributors, and more than 50% of the returns are due to this.
19. Dual TV sockets: another satellite line and cable TV are installed in the home. In addition, dual telephone sockets are suitable for 2 numbers, and multi-port computer sockets are suitable for LAN wiring.
Principle of wall point switch
The touch switch is an intelligently controlled wall switch, which itself needs to consume a certain amount of power. In standby, the standby power of the single-fire smart switch is powered by the current flowing through the electronic ballast to the smart wall switch control circuit. If the standby input current is small, the standby circuit will not work. If the standby input current is large, it will cause problems such as cold flashing and red filament after the electronic ballast lamp is turned off.
What is the principle of the switch socket
An electronic switch refers to an operating unit that uses power electronic devices to make a circuit on and off, and includes at least one controllable electronic valve device. Digital electronic switch: It uses electronic components to form a bistable circuit. This kind of circuit is composed of useful integrated circuits composed of discrete components. There are also monolithic integrated circuits that are bistable. There are also many types, such as D flip-flops. JK triggers, such as thyristors, photoelectric switches, various switch-type digital sensors, can be used for switching power supplies, signal detection and identification, etc. Analog electronic switches are also called solid state relays, which have no contacts, long life, and are not restricted by the use environment. There are triodes in electronic switches, and the triode is cut off can be regarded as disconnection. The saturation of the triode can be regarded as on
