The solution to the problem of high resistance on the touch switch

Why do we use the tactile switch to have a high resistance value? What is the reason? Let's give you a detailed introduction below.
At present, many customers don't know much about the resistance value of the switch. Generally, the resistance value of the switch is controlled below 30 m Euro, so the touch function and life of the switch are very outstanding, but some of the switches have high resistance value after passing the furnace temperature and life test.
If the resistance is high, it means that the touch area of the shrapnel and PIN foot of the switch is too small, and the touch area is too small to cause the switch not to touch. Once the switch is not touched, it will be bad. Therefore, we should be careful about the resistance of the switch, the shrapnel and PIN foot on the plating requirements are relatively high, plating resistance will be low.
When the switch passes the life test, the shrapnel will wear out. If the electroplating is thin, the resistance will be high and the switch will be bad.
