Information

The basic concept is: the human body induces electricity and voltage on the same screen. When touching the body or pressing the self-locking switch, the buffer level will be cropped, amplified and reshaped into a standard MOS pulse signal.

When the touch delay time exceeds 32ms and is less than 332ms, the control loop part of the operation logic is in the switch operation state. When the touch delay time exceeds 332ms, a part of the control loop of the control logic is in the dimming operation state, and the phase angle of the single pulse of output conduction changes for a period of time in the middle of 41°~159°. , And divided into fast according to the perception of the human eye. Slow and pause these three processes.

After the touch is completed, the color memory will establish a memory for the phase angle. If the applied touch time is greater than 32ms but less than 332ms, and the power circuit is off, the phase angle remains in this part of the memory to ensure that the power circuit is below it. When it is turned on once, the phase angle originally selected will be maintained, and the light source will maintain the original chromaticity. Turn on the synchronization of single pulse and voltage, the lock-in amplifier ensures that the digital clock in the power circuit works normally, which is also caused by it. In addition, the power supply circuit also has a remote control function (that is, the remote side is turned on) and a function of gradual sleep (that is, from bright to dark, and finally off), the duration of which is set by an external circuit.

Advantages of self-locking switch compared with traditional switch

Self-locking switch, low noise and long life. With backlight, and the anti-discharge effect is very good. Self-locking switches do a good job in these aspects. 1. The function of the self-locking switch is to make proper wiring. The specific phase difference sequence is to connect the left end to zero and the right end to the fire grounding device.

2. First, you should correctly understand the wiring of the switching power supply at home, and then you can install the switch, and according to the requirements of our country, red, green and yellow respectively represent the three-phase live zero line. , Blue represents the neutral point (Neutral point), and the two colors of yellow and green are wire connectors (maintenance wires). Everyone must be aware of this, otherwise the installation will not be able to connect to the power source.

3. It must be noted that if the wire connector cannot receive the live wire or the neutral wire, it will cause a safety production accident. Although the live and neutral wires may be incorrectly connected, there are potential safety hazards.

4. Fast wiring: insert the stripped wire knot into the wiring hole to connect, no need to use screws to install the card, and no need to use special tools (such as electric switch knife). There is a reed in the wiring hole, which will be stuck when pulled out in the opposite direction. It is more convenient to insert on one side. It is necessary to poke the surgical thread removal hole or press the surgical thread removal button to remove the thread.

Frequently Asked Questions about Touch Application:

1. The self-locking switch stipulates that screws should not be fixed. Remove the control panel and store the screws. Third-party screws will be compatible with machines and equipment.

2. Self-locking switch cannot be used. It may be that the main gate has not been opened yet, so the inspection can be performed.

3. The integrated IC of the self-locking switch is the key component. It is recommended to choose products with quality assurance and high sensitivity produced by well-known brand manufacturers.

4. The wiring methods of self-locking switches of different well-known brands are different, so be sure to pay attention when buying.

5. The self-locking switch has different installation methods, which can be selected according to application requirements.

How to fix the self-locking switch does not work

There are many reasons for the failure of the self-locking switch, which may be caused by the poor contact of the contacts. The switching power supply must be disconnected, and then the contacts must be cleaned and cleaned for maintenance. The circuit board will be burned and must be replaced. It is recommended to contact professional and technical personnel for actual operation. Maybe the switch is stuck. You can turn off the switch power supply, and then remove the switch control panel to see if there is dirt stuck.
