-- What is a micro switch -- one
A micro switch is a contact mechanism with a small contact interval and a quick-action mechanism. It uses a specified stroke and a specified force to switch. It is covered by a shell and has a driving rod on the outside. Because of the contact spacing of the switch It is relatively small, so it is called a micro switch, also called a sensitive switch. The electrical text symbol is: MS.
-- The working principle of the micro switch--
The working principle of the micro switch is: the external mechanical force acts on the action reed through the transmission element ((press pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, it produces an instantaneous action to make the action The moving point at the end of the reed and the fixed contact are quickly connected or disconnected. When the force on the transmission element is removed, the action reed produces a reverse action force. When the reverse stroke of the transmission element reaches the critical point of the reed, the reverse action is completed instantaneously. The contact spacing of the micro switch is small, the action stroke is short, the power is small, and the on and off is rapid. The action speed of the moving contact has nothing to do with the action speed of the transmission element. The micro switch is based on the pin type, which can be derived from the button short stroke type, the button large stroke type, the button large stroke type, the roller button type, the reed roller type, the lever roller type, the short moving arm type, the long moving arm type, etc. Microswitches are used in electronic equipment and other equipment for automatic operation and safety protection of switching circuits. Micro switch is divided into large, medium, small, according to different needs can have waterproof type (put in the liquid environment to use) and ordinary type, the switch connects two lines, for electrical appliances, machines and so on to provide on-off operation, widely used in the mouse, household appliances, industrial machinery, motorcycles and other places, the switch is small, but plays an irreplaceable role.
Micro switch is widely used in automobile control, home appliance control, industrial control field. A variety of installation dimensions to meet different installation requirements.

The touch switch is called the key switch, also known as the sensitive switch. When in use, the switch function is closed and turned on by pressing the switch operation direction under the condition of satisfying the operation force. When the pressure is removed, the switch is turned off. Its internal structure is turned on and off by the force change of the metal elastic sheet.

The difference between the working principle of the light touch switch and other key switches
The light touch switch with light can turn on the switch, and there is also an indicator light to let you know clearly whether the switch has been turned on.
Custom micro switch, customers need to provide what technical parameters
As the performance of the micro switch is constantly upgraded, the functional configuration has also been significantly improved. Therefore, the use will become more and more common. Then, some customers will customize the micro switch according to the purpose, in order to be consistent with the application scenario.
