Different silicone keys work differently, and the causes of failure are different. The following Cushwa Electronics will introduce the causes of failure of different silicone keys and the solutions to the failures encountered.

A. Metal spring-type silicone keys Working principle: the external press to the spring a force, the spring conveys the external force to the spring below the metal sheet a force, the metal sheet is connected to the circuit board by pressure to achieve the role of connectivity.
 Failure causes.
 1, the metal sheet surface dirt Solution: cleaning the surface dust impurities with alcohol.
 2, the spring is not properly positioned solution: adjust to the correct position.
3, the metal sheet corrosion, fracture, defective solution: replace the metal sheet.
 Second, improved conductive silicone keys
Cause of failure.
 1, conductive material surface dirt Solution: Clean the conductive material with alcohol.
2, conductive material wear and tear solution: conductive material and circuit board contact points to increase some conductive material;.

To sum up: in the face of the problem of silicone key failure, you should find out where the problem lies, first of all, is the spring type or conductive type? The only way to find out where the problem lies is to choose the right solution, such as: choose to clean up the metal sheet after the surface dirt with alcohol. In order to effectively avoid the waste of silicone keys that can not be used after the failure.
