Classification and main uses of key switches
The key switch mainly refers to the light touch key switch, also known as the light touch switch. When in use, the switch function is closed and turned on by applying pressure to the operating direction of the switch to meet the conditions of the operating force, and the switch will be turned off when the pressure is removed. It is mainly composed of insert, base, shrapnel, button and cover. Button switches are more common, but button switches are not unique, and button switches are also classif

The key switch mainly refers to the light touch key switch, also known as the light touch switch. When in use, the switch function is closed and turned on by applying pressure to the operating direction of the switch to meet the conditions of the operating force, and the switch will be turned off when the pressure is removed. It is mainly composed of insert, base, shrapnel, button and cover.
Button switches are more common, but button switches are not unique, and button switches are also classified! It may be a secret that only many professionals know. Indeed, unprofessionals only know that there is only a metal sheet in the key switch, and others do not know. When using it, just tell the boss that you need a key switch, the boss will filter out a key switch, and then pay directly. Finally, install the key switch you bought home and use it.
So, how are key switches classified? Key switches can be classified into two types. One is what we often say, the inside of the key switch is made of metal sheets, which is called the key switch. It is also what we can often see. However, there is also a kind of key switch, which is different from the key switch we often talk about. The internal structure of this key switch is different from the key switch we usually talk about. This kind of key switch mainly uses electric rubber as the connection circuit, and then this is also called a key switch, but there is another name, which is a conductive rubber key switch. The use of this key switch is very good, but the resistance of this key switch is relatively much larger than that of the metal sheet key switch. Generally in the 100-300n.
The key switch has the advantages of small contact resistance load, accurate operating force error, and diversified specifications, and has been widely used in electronic equipment and white goods. 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.
The main uses of key switches are color TV sets, black and white TV sets, audio equipment, video recorders, video cameras, computers, game consoles, fax machines, walkie-talkies, batons, machine tool control devices, copiers, printers, electronic instruments, meters and other household appliances.
