How to identify the quality of the tact switch

the quality of tact switch products is reflected in: .
1. the parts have high machining accuracy and the coating is good or bad;
2. the size of the on-resistance.
3. the hand feel is suitable for the level.
4. whether the service life meets the design points.
5. whether the security protection level meets the requirements of the usage scenario.
parts processing technology: the pin base material of the tact switch is copper tape or phosphor copper tape. after stamping, in order to prevent air oxidation and reduce circuit resistance, a plating process is required to solve the pin problem. in this link, stamping and electroplating will be directly related to the high precision of the terminal and the quality of the plating. so a premium tact switch is here to tightly control both processes.
