What Is a Touch Switch?

Touch switch is an emerging product of scientific and technological development. He generally refers to a type of wall switch designed using the principle of a touch-sensing chip, which is a replacement for the traditional mechanical button-type wall switch. Touch switches that can be more intelligent and more convenient to operate have the incomparable advantages of traditional switches, and are a very popular decorative switch for home products.

Touch switches are classified into resistive touch switches and capacitive touch switches according to the switch principle. According to the wiring method, they are divided into single-fire wire touch switches and two-wire touch switches (fire wire and neutral wire). From a global perspective, most countries use single-fire wire wiring rules. Therefore, early touch switches were dominated by single-fire control. With the deepening of applications, the stability of zero and hot wire control is higher. The load is greater. The market is dominated by zero and fire control ^[1]

The touch switch is a kind of intelligently controlled wall switch, which itself needs to consume a certain amount of power. During standby, because the single-fire smart switch takes power by standby,

The touch-sensitive operation panel is rapidly applied in many fields because of its ruggedness, wear resistance, insulation, dust and water resistance, and its beautiful and novel appearance. However, many products using touch-sensing panels have encountered difficulties such as production debugging, touch-sensing panels are unstable in operation, and are prone to misoperation in humid and strong interference environments, causing customers to return goods.

Production debugging is difficult, and it is impossible to go to mass production. The touch-sensitive panel is unstable. It is easy to malfunction in a humid and strong interference environment, causing customers to return. The product has poor long-term work stability, and the product that has been debugged on the production line, after transportation or long-term work, changes in sensitivity or often erroneously increases the after-sales cost.

These reasons have caused many manufacturers to both hope to adopt this new technology and have doubts about whether products using this technology can work stably. Because simple trials of touch-sensitive panels often can't find anything wrong. Often, it is not until the customer uses it for a period of time after delivery that various problems will appear. This will inevitably bring cost and reputational losses to manufacturers.

The outstanding problem that customers encounter with touch-sensitive panels is sensitivity and reliability (no misoperation). It is difficult to maintain stability in various environments, especially for long-term work.

The mainstream technology of touch-sensing panels is implemented using capacitive sensing technology. Because the capacitance of the finger on the induction pad changes very little, and as the thickness of the isolated insulation panel increases, the size of the capacitance decreases exponentially. After approximately 5mm of tempered glass, a human finger can only bring about a capacitance change of less than 0.5PF. For such a small measurement quantity, changes in humidity, temperature, electromagnetic interference, and power supply interference will greatly affect the measurement results of the measurement circuit. Without special and professional treatment methods, it is difficult to ensure the stable operation of the touch-sensitive panel, especially the long-term stability in various harsh environments. ^[1]

The intelligent switch is based on the installation of ordinary switches and uses single fire wire control, and ordinary electricians can install it. Each switch can be said to be a separate centralized controller. There is no need to add any other equipment during installation, and the installation is quick and easy. We are more receptive.

1. Mutual control: All lights in the room can be controlled on each switch, and up to 27 channels can be controlled on each switch. 2. Illumination display: The status of all electric lights in the room will be displayed on each switch.

3, a variety of operations: can be manual, infrared remote control, remote operation (can control the lights in this room in other rooms).

Example 1: Before going to bed at night, I found that the child's room light is still on. You can immediately know which light in the child's room is on the smart switch in your room. Then you can manually or remotely control the smart switch in your room. control.

Example 2: For users of villas or duplex buildings, due to the large housing, they often return to their room to rest, and suddenly think that the lights in other rooms are not turned off. The smart switch will have a lighting display and remote control to solve such problems.

4. Home control: You can directly turn on the lights connected to the home switch.

For example: Just like the 3 on of a normal switch, you can directly press the lamp 1, lamp 2, lamp 3 to turn on and off the lamp.

5. Home position lock: all switches can be prohibited from operating the lights in this room

For example: If you are reading in the study room and you don't want to be disturbed by others, the smart switch can lock the light in your study room, allowing you to read the book with peace of mind.

6, all-off function: one button can turn off all the lights in the room or turn off the lights in any room.

For example: preparing to go out at night, it is troublesome to turn off the lights one by one like a normal switch. With a smart switch, go to the door and press the full key directly for 3 seconds to turn off all lights or turn off each room individually.

7. Power failure protection: When the power is off, all the lights will be turned off and there will be a sound prompt.

For example: if the light is on, and there is a sudden power failure, the smart switch will automatically turn off all the lights when a call comes in, and there will be a call reminder, and ordinary switches can't achieve such a function.

8. Status indication: The status indicator on the switch can be turned off separately, press any key to resume, without affecting other switch operations.

For example: the living room light is on at night, and the other room lights are on. I go to bed first. I do nt want the display on the panel of my room, but I do nt want to turn off the lights in the other room. The indicator is enough.

9. Automatic luminous: humanized automatic luminous is turned on when the smart switch leaves the factory

For example, when you come home at night, the smart switch panel will have a very humanized luminous luminous light to let you easily find the switch, unlike ordinary switches, feel the position of the switch with your hand.

10. Infrared remote control: You can use infrared remote control to remotely control all switches.

For example: when you are lying in bed, you want to turn off the lights in your room, just like turning off the TV, you can use the remote control to operate.

11, memory storage: built-in IIC memory, all settings are automatically memorized.

12. Quick setting: Set the name of each switch conveniently and quickly.

13. Easy installation: The installation dimensions and wiring methods are the same as ordinary switches, and two signal wires are required to connect the switches in parallel.

14. Affordable price: The number of switches required to install this switch is much lower than that of ordinary switches (usually one per room), and they can control each other without the need for ordinary dual-control installation methods, so many ordinary switches and wires can be saved.

15. Convenient maintenance: The failure of one switch will not affect the use of other switches. Users can simply install new smart switches and install them. Ordinary switches can be used directly during maintenance and will not affect normal lighting.

16. Good safety: The switch panel is a weak current operating system, no sparks are generated when the lamp is turned on / off, and it is safe to use in bathing and places prone to water.

17. Product size: Standard 86-type installation size, easy to replace ^[1] .
