The key switch has the advantages of small contact resistance load, accurate operating force error, and diversified specifications. It has been widely used in electronic equipment and white goods, such as: audio-visual products, digital products, Remote control, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, money detector pens, laser pen buttons, etc. Because of the environmental conditions of the key switch (elastic force with pressure less than 2 times/environmental temperature and humidity conditions and electrical performance), large equipment and high-load buttons are directly replaced by conductive rubber or dome switch hardware shrapnel, such as medical equipment, TV. machine remote control, etc.
works Principle: The operating force of the key switch 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. Guide turtle rubber switch generally has two structures. The operating force curve varies greatly with the geometry of the rubber block.
