Analysis of touch switch structure
Time: 2016-08-05 10:14:49 Copyfrom: Dongguan Yu Chang Electronic Science and Technology Co., Ltd.
The touch switch is divided into two categories: the use of metal reed as said touch switch switch contact sheet, the contact resistance is small, the cluster 20mn. Feel good, there is "tick" crisp sound. 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 key is to rely on the touch switch structure moves down, make contact spring or conductive rubber block contact welding, forming path.
The operating force and reed touch switch and the state of the. Start force and compression distance is the reed Reed was reduced to 5. % a 70% when the operating force suddenly reduced, and accompanied by "tick" sound. Guide turtle rubber switch generally has two kinds of structure. The operating force curve varies with the geometry of the rubber block.
