Button switch classification
Time: 2016-08-05 10:45:49 Copyfrom: Dongguan Yu Chang Electronic Science and Technology Co., Ltd.
Push button switch is divided into two big classes: using metal spring as the switch contact call button switch, contact resistance is small, feel is good, "tick" sound crisp. Conductive rubber is used as the switch of the contact path, and the conductive rubber is used as a conductive rubber switch. Switch feel good, but the contact resistance is large, generally in the 100 one 300n. The structure of key switch is on the button down, make contact spring or conductive rubber block contact welding, forming path.
The operating force and the reed key switch the state of the. Began to force and the spring compression distance is more than the reed compressed to 5% - 70% operating force suddenly reduces, and accompanied by a "tick" sound. Guide turtle rubber switch generally has two kinds of structure. The operating force curve varies with the geometry of the rubber block.
