2 Structure

The touch switch is divided into two categories: the metal spring is used as the touch switch of the switch contact piece, and the contact resistance is small, and the cluster 20Mn is used as the switch. Feel good, with "tick" sound. Conductive rubber

A switch used as a contact path is called a conductive rubber switch. Switch handle is good, but contact resistance is large, generally in 100 300n. The structure of the touch switch is moved downward by the keys

The contact spring or conductive rubber block contacts the welding pad to form a passage.

The operating force of the touch switch is related to the condition of the reed. Start force and compression distance is the reed Reed was reduced to 5. The operating force suddenly decreases when% 1 70%, accompanied by "drip"Answer sound. Guide turtle rubber switch generally has two kinds of structures. The operating force curve varies greatly with the geometry of the rubber block.
