Introduction
Definition and importance of micro switches
Micro switches, also known as miniature snap-action switches, are small switches that are designed to operate rapidly with minimal force. These switches are highly reliable, efficient, and fast in their operation, making them widely popular in various industries and applications. They are often used in automation systems, appliances, control panels, medical devices, automotive applications, and more.
The importance of micro switches lies in their ability to quickly and accurately control electrical circuits. When the actuator of the micro switch is pressed, it lifts a lever that moves the contacts into the proper position. This movement triggers the switch to open or close the electrical circuit, enabling devices to function as intended. Micro switches feature a distinctive “clicking” sound when pressed, providing audible confirmation of their operation.
