Metal touch switch is divided into two categories: the use of metal reed as a switch contact piece that the metal touch switch, contact resistance, cluster 20mn. Feel good, a "tick" crisp sound. The use of conductive rubber as a contact path switch is commonly known as the conductive rubber button switch. Switch feel good, but the contact resistance, generally 100 a 300n. The structure of the metal touch switch with light is to move downwards by the key to make the contact spring or the conductive rubber block contact with the solder joint to form a path, and the other key is provided with a halo of the LED light.
The operating force of the waterproof metal touch light push button switch depends on the state of the reed. The starting force is proportional to the compression distance of the reed when the reed is compressed to 5. Suddenly a decrease in operating force with% -70% accompanied by "ticking" sound. Guide turtle rubber switch generally have two kinds of structure. Operating force curve with the rubber block geometry is very different
