How to connect wires by touching the switch lightly
In the process of use, touch the switch gently to meet the operating force conditions and apply pressure to the switch to open and close. When the pressure is released, the four pin touch switch will be closed. The internal structure of the four pin touch switch relies on the metal spring to protect the stress, so as to achieve connection and disconnection. This is just one of the four foot touch switches. If you want to know more about the four foot touch switch, please continue to read!
In fact, the light touch four pin switch is the same type of switch as the light touch switch commonly used in our life. The light touch four pin key switch cannot lock itself during use. However, as long as we press it once, the signal of the four corner switch will change once.
How to connect the four corners of the light touch switch?
The four foot touch switch cannot be self-locking during use, but the signal of the four corner switch will change once the user presses it once. As for how to connect the four corners of the touch switch, this is very important for electricians, as follows:
1. Adjust the multimeter to the diode;
2. First, measure any two feet in the four corners to determine which two corners are conductive and which two corners are disconnected;
3. Press the key, measure any two feet, and then judge which two corners are conductive and which two corners are disconnected;
4. To start the disconnection, press the key to press the conductive feet as the two corners of the welding.
Wiring diagram of touch switch
The figure above shows the dimension diagram and circuit diagram of the four pin touch switch
According to the experience of professionals, direct welding can be carried out as long as it is diagonal.
It should be noted that: the working principle of the key switch is that when the key is pressed, the two patches are close to each other, that is, they are connected; When it is released, the patch is disconnected.
Operating principle of four pin key switch
The working principle of this switch is similar to that of an ordinary button switch. It is composed of normally open contacts and normally closed contacts. In a four pin button switch, the role of normally open contacts is that when pressure is applied to normally open contacts, the circuit is turned on; When the pressure is removed, the original normally closed contact is restored, which is called disconnection. This force is the action of opening and closing buttons with our hands. In a word, the working principle of the four pin key switch is well understood.
In fact, the working principle of the four pin light touch switch is similar to that of the ordinary button switch, which is composed of normally open contacts and normally closed contacts. In the four pin key switch, the function of the normally open contact is that when the pressure is applied to the normally open contact, the circuit will be turned on; When this pressure is removed, the original normally closed contact is restored, which is called disconnection. This force is the action of opening and closing buttons with our hands.
