The micro switch in the mouse is located on the circuit board under the button. When the button is pressed next time, the metal reed in the micro switch triggers once, and sends a signal to the computer, then resets and completes a click. Because fretting is a pure physical device, every click actually causes wear and tear, which is why some manufacturers take the number of clicks as a mouse life parameter.
Micro-switch is a kind of pressure-activated fast switch, also known as sensitive switch. Its working principle is that the external mechanical force acts on the action spring through the transmission element, and accumulates the energy to the critical point, resulting in instantaneous action, so that the dynamic contact at the end of the action spring and the fixed contact can be quickly connected or disconnected.
What are the important roles of micro-switch
When the action force on the transmission element is removed, the action spring produces the reverse action force. When the reverse stroke of the transmission element reaches the critical point of the action of the spring, the reverse action is completed instantaneously. The contact spacing of the micro switch is very small, and it has the characteristics of short travel, small power and quick on-off.
Micro-switch is widely used in electronic equipment, instruments, mines, power systems, household appliances, electrical equipment, as well as military fields such as aerospace, aviation, naval ships, missiles, tanks and so on.
