Knowledge Sharing – About Micro Switches

The micro switch is a pressure-actuated quick switch, also known as a sensitive switch. Its invention is attributed to a man named Peter McGall in Freeport, Illinois, USA in 1932.
The working principle of the micro switch is that the external mechanical force acts on the action reed through the transmission element (push pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, an instantaneous action is generated, and the end of the action reed’s the moving contact and the fixed contact are quickly connected or disconnected.When the force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously.

The contact distance of the micro switch is small, the action stroke is short, the pressing power is small, and the on-off is fast. 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 push pin type, and can be derived from the button short stroke type, the button long stroke type, the button extra large stroke type, the roller button type, the reed roller type, the lever roller type, the short boom type, and the long boom type. and many more.
Micro switches are used in electronic equipment and other equipment in automatic control and safety protection devices that require frequent switching of circuits. They are used on various devices to sense “on” or “off” states.
It has been more than 90 years since the invention of the micro switch. Today, the micro switch has become an industrial necessity with an annual consumption of more than 100 billion pieces. It has long been closely related to people’s work and life. As an ordinary person, even if you and the micro switch, there seems to be no intersection, but as long as you want, in any home or public place, you can find at least one or more micros witches on your car, on the computer, on the rice cooker, on the air conditioner , washing machine, dishwasher, etc.
