Before using the light touch switch, we must detect it. This is to prevent the light touch switch from breaking down after installation. So how to detect it? Let's give you a detailed introduction.
Light touch switch terminals with lamp can be divided into straight foot, bend foot, welding plate type, fast connection and so on. When the light touch switch is detected, the two pens are connected with the two lead wires of the light emitting diode, such as the pin is deflected half, and there is a bright spot in the light emitting diode, indicating that the light emitting diode is positively connected. At this time, the positive pole is connected with the black pen (connected with the positive pole of the battery in the table); and the negative pole is connected with the red pen (connected with the negative pole of the battery in the table).
The manufacturer of miniature light touch switch introduced that the two pens should be adjusted and connected with the light emitting diode. This is the reverse access, and the needle should not move. If the meter needle is deflected to the head or does not move regardless of the forward or reverse access, the light emitting diode is damaged.
A good light touch switch is also very important for the life of the whole product. For example, computer keyboard, remote control and so on. If it is a poor quality light touch switch, the metal shrapnel will lose its elasticity and become ineffective after frequent press. Therefore, it is also very important to select the light touch switch. The key factors affecting the quality of light touch switch with lamp are the protection, solderability, reliability of conduction, life, handle, production process and installation size of light touch switch.
Micro Touch Switch Company introduced that the competition in the light touch switch industry is very fierce. Sometimes the tested objects move to the proximity switch one after another at a certain time interval, leaving one after another, so they repeat constantly.
