Because the scope of use of touch switches is very extensive, the places of use may be very large, such as public squares, large dance halls, etc., or it may be on very small electronic products, such as digital cameras, mobile phones, massagers, etc. Therefore, in order to adapt to different usage scenarios, the volume specifications of touch switches are divided into many categories. Traditional touch switches still have certain safety hazards, But now the fifth generation light touch switch has been developed, and the new type of light touch switch uses thin film as the contact point, solving many problems such as high resistance and poor touch. 4.5x4.5 is divided into three types of light touch button switches: plug-in, patch, and edge triangle. The size and height of the 4.5x4.5 light touch switch are mainly 3.8 and 5, which are generally four pin plug-in light touch switches. The size and height of the 4.5x4.5 patch touch switch mainly include: 3.2, 3.8, 4.0, 4.5, 4.8, 5.0, 5.5, 6.0, and 7.0. There are nine types of patch touch switches, generally only four feet, also known as four foot patch switches. The dimensions and heights of the 4.5x4.5 edge triangle light touch switch mainly include: 3.8, 4.3, 4.8, 5.0, 5.5, 7.0, 8.0, among which the height edge triangle light touch switch button, also known as the edge triangle light touch switch. 6x6 is divided into two types of light touch switch buttons: patch and plug-in. The size and height of the 6x6 patch light touch switch mainly include: 4.3, 4.5, 5, 5.5, 6, 7, 8, 9.5, 10, 12, and 13 eleven types of height patch button switches, mainly four foot buttons. The light touch 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 Major appliance, such as audio and video products, digital products, remote controls, communication products, household appliances, security products, games, computer products, fitness equipment, medical equipment, currency verification pens, laser pen keys, etc. Because the light touch switch directly replaces large equipment and high-load buttons with conductive rubber or pot switch hardware shrapnel due to environmental conditions such as elastic force less than twice the applied pressure/environmental temperature and humidity conditions, as well as electrical performance, such as medical equipment, television remote controls, etc.
