Tact switches are divided into two categories: tact switches that use metal reeds as switch contact pieces, the contact resistance is small, and the cluster is 20mn. Feels good, has a "tick" crisp sound. A switch that uses conductive rubber as a contact path is customarily called a conductive rubber switch. The switch feels good, but the contact resistance is large, generally 100-300n. The structure of tact switches is to move down by the key, so that the contact reed or the conductive rubber block contacts the solder piece to form a path.
The operating force of tact switches is related to the state of the reed. The starting force is proportional to the compression distance of the reed. When the reed is compressed to 5% to 70%, the operating force suddenly decreases, accompanied by a "tick" sound. Rubber switches generally have two structures. The operating force curve varies greatly with the geometry of the rubber block.
