Anonymous users2024-02-12It can be seen from the wiring diagram of the touch switch that it has power in and out, which must not be mistaken, and other aspects are the same as ordinary lamp wiring. One is connected to the live wire, one is connected to the bulb, and the other end of the bulb is connected to the neutral wire. Alternating current.
There is no positive and negative difference between the live line and the zero line column, as long as the two wires are not touched together, there is no strict requirement for which hole to connect.
Touch open-loop installation precautions.
When installing according to the wiring diagram of the touch switch, remember to ensure the safety during the installation. We recommend that it is best to have a professional electrician do the work. Before the specific installation, prepare all kinds of necessary tools in advance to facilitate the installation.
During installation, it is better not to operate with a screwdriver live.
and other operating tools must also be insulated.
The wiring diagram of the touch switch is also not complicated, and after installation, we recommend conducting an on-site inspection to ensure that it is safe to use after installation. The touch switch should also be maintained in the later stage, and do not squeeze it hard in daily life. In order to ensure its safety, regular maintenance is also necessary.
Remember not to touch the surface of the switch with water, although it has a certain waterproof effect, but after all, the switch is a long-term use of the device, it is inevitable that the phenomenon of aging will occur in advance.

Anonymous users2024-02-06Due to modern society, home decoration is becoming more and more exquisite, and the switches used by many families have become touch switches. And it's not hard to see that more and more public places can also widely use touch switches. It is true that touch switches are indeed more convenient to use than traditional switches, and they are also more beautiful than traditional switches in appearance.
As everyone knows, the touch switch is very cumbersome in the process of internal installation and wiring, and it is no exaggeration to say that the wiring of the touch switch is a great project. Let's take a look at the introduction of switch installation experts.
1. How to wire the touch switch
There is power in and out of the touch switch, don't make a mistake, and the others are the same as the ordinary lamp. One is connected to the live wire, the other is connected to the bulb, and the other end of the bulb is connected to zero. There is no positive or negative difference between the live wire and the neutral line binding post of the alternating current, as long as the two wires do not touch together, which hole can be connected.
It is best not to operate with electricity. If it is not operated live, it is necessary to pay attention to the screwdriver and other tools to be insulated, and pay attention to the fact that the tool cannot touch another wire during operation.
Second, the touch switch wiring**
The rectifier bridge composed of four diodes and the one-way thyristor VS constitute the main circuit of the switch, and the control loop of the switch is mainly composed of the integrated circuit M668. The 220V pulsating DC output by the rectifier bridge is limited by R1, VD5 is regulated, and the C1 filtered output is about 6V DC and sent to the 8th and 1st pin of the IC respectively to supply power to the IC. The human touch signal is sent to the touch sensing input terminal SEN of the IC through M, R7 and R8, that is, 2 pins, and the 7 pins of the IC is the trigger signal, and the output end TR will output a series of touch alarm delayed pulse signals, which are added to the gate of VS through C3 to make the VS turn on light.
If you touch the foot again, it will stop outputting a trigger pulse signal, and when the alternating current crosses zero, the light will go out.
The ICs of R4 and C2 internally trigger the external oscillation resistor and oscillation capacitor of the pulse oscillator. The synchronization signal of the IC is input by Pin 5 after the voltage division of R2 and R3. Pin 4 of the IC is the function selection end, and the VCC high level is connected now, and the touch function is:
Touch M once and the light will be on; Touch it again, and the light goes out. If you change the 4 pin to the VSS side low, it will be a 4-stop dimmer switch, and the brightness will be changed once at a time.
How to wire the touch switch? The above-mentioned switch installation experts gave a detailed explanation. In fact, the installation of the touch switch is difficult to say, and it is simple to say that it is simple.
Here, it is recommended that if you have a little understanding of the knowledge of circuit electricians, or have a certain foundation in switch installation, you can follow the above introduction to install the touch switch by yourself. However, if you don't understand the circuit and switch installation at all, you should go to the relevant store to find a professional switch installation master, so as to ensure both safety and the quality of switch installation.

Anonymous users2024-02-051. Use the two ends of a wire to connect to the L1 of the two switches, and the two ends of a wire are connected to the L2 of the two switches, and these two wires are called double wires. Then use a wire to connect one end to the zero line and one end to the L of a switch, and cut off the lamp in the middle. The other switch is connected to a live wire.
2. Connect the L of two switches at both ends of a wire, and cut off the lamp in the middle. The L1 of both switches is connected with a fuse wire, and L2 is connected with a zero wire.
3. The other ones are the same as the ordinary lamp wiring. One is connected to the live wire, the other is connected to the bulb, and the other end of the bulb is connected to zero. There is no positive or negative between the live wire and the neutral terminal of the alternating current, as long as the two wires do not touch together, which hole can be connected.
It is best not to operate with electricity. If it is not operated live, it must be noted that screwdrivers and other tools should be insulated, and the tools should not touch other wires during operation.

Anonymous users2024-02-04There is a touch switch wiring methodSingle-wire touch switch and two-wire touch switch.
Touch switches are divided into resistive touch switches and capacitive touch switches according to the principle, and are divided into single live wire touch switches and double-wire touch switches according to the wiring mode.
Touch switch is a kind of wall switch designed by the principle of touch sensor chip, without traditional mechanical mechanism, because of its sturdy, wear-resistant, can be insulated, dust-proof, water-proof, and beautiful and novel in appearance, longer service life, quickly applied in many fields, become a hot technology, in many high-end hotels have been widely used.
When families choose a touch switch, the most important thing to pay attention to is whether to choose a single-fire touch switch or a zero-fire touch switch.
The so-called single-fire touch switch can directly replace the traditional switch in the home, because the traditional switch is also a live wire, and then a wire to household appliances (such as electric lights), so it is called a single fire, and its wiring is the same as the traditional switch wiring.
The single-fire version of the smart switch "integrates 1 "variable resistor" inside, which is connected in series with the bulb, if you want to turn off the bulb, the resistance is adjusted very large, close to the open circuit, but not the open circuit, there is still a small current in the line, which can supply power to the "control chip". The single-fire touch switch can only be connected to devices with less than 800 watts of power.
The so-called zero-fire touch switch refers to the control chip terminal of the neutral wire and the live wire connected to the switch at the same time.
When the lighting is turned off, there is still neutral and live wire power supply on the chip, and it supports devices with up to 2500 watts of power.
If you want to control high-power lighting, before choosing the switch, you should make sure that the zero wire is embedded in the switch, because the traditional switch will not have a neutral line when laying the wire, only the live wire and the outgoing wire.
After the Siemens MP277 touch screen OS is updated, the programs in you are gone, all you need to make sure you have a backup of the source program before you update the OS (factory reset). >>>More

Because there is a metal substance on the screen that can conduct electricity, when the finger touches it, the capacitance here changes, and the touch screen reaction is completed.
Touch screen:
Also known as "touch screen", "touch panel", is a kind of inductive liquid crystal display device that can receive input signals such as contacts, when touching the graphic buttons on the screen, the haptic feedback system on the screen can drive various connection devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio and video effects through the liquid crystal display screen. As the latest computer input device, touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It gives a new look to the multi-first, and is a very attractive new multi-interactive device. >>>More
To put it simply, a capacitive screen is more sensitive than a resistive screen, and it is a touch screen in the true sense. However, capacitive screens and resistive screens cannot be said to be good and bad, depending on their preferences. The capacitive screen is sensitive, so the operation on the screen only needs to be touched with your fingers and gently sliding, so generally mobile phones with capacitive screens do not have stylus, resistive screens, and you need to work harder on the resistive screen, most of the stylus we see are resistive screens, such as Nokia's latest flagship product N900 is a resistive screen, and Nuoji 5800 and other mobile phones such as Apple iPhone and Samsung i8910 are capacitive screens, and capacitive screens have stricter use conditions than resistive screens, such as temperature, Humidity and other theoretical, the use of capacitive screen ambient temperature requirements in 0-35, resistive screen in -15 to 45 This may be a bit exaggerated, and there are no such strict requirements in actual use, otherwise people's iphones will not be sold in slightly cold or hot countries, hehe.
