Factors affecting the lifespan of touch switches
Number of views:1522 Time: 2024-01-03

The popularity of various touch switches in PCB circuits and their lifespan is a crucial performance factor. The factors that affect the lifespan of touch switches are approximately as follows:


1. The usage environment, temperature, and humidity have a certain impact on the lifespan of the touch switch.


2. According to the pressure level, our light touch switch usually has a pressing force of 100GF/160GF/250GF, etc. The lighter the force, the higher the lifespan, and vice versa.


3. Overload current, excessive current can easily burn out the surface plating of the shrapnel and contact points. When the plating is damaged, lightly touching the switch can easily cause poor contact.


4. Processing technology: The processing technology strictly follows the specifications and procedures, and prevents the factors mentioned in the precautions.


By controlling the above points well, the service life of the touch switch is generally longer than that of our laboratory testing
