related knowledge for Internal structure of micro switch

- Dec 12, 2018 -

The internal structure of the micro switch is introduced. Many people have a certain understanding of the micro switch. So, do you know what characteristics of his internal structure? The following small series will take you to see the internal structure of the micro switch and some related knowledge.

Simply put, the working principle of the micro switch is that the external mechanical force passes through the transmission component, such as pin, button, lever, roller, etc., and the force acts on the action reed, and the energy is accumulated to the critical point to generate the instantaneous action. , the moving contact at the end of the action reed is quickly connected with the fixed contact

Pass or disconnect. When the force on the transmission component is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneously completed.

Therefore, the main features of the micro-switch's contacts are: small spacing, short stroke, low power, and fast switching.

When the pin-type micro-switch is used as the basic type, the micro-switch can be divided into a button short stroke type, a button large stroke type, a button large stroke type, a roller button type, a lever roller type and the like.

In electronic equipment, etc., when used in automatic control of circuits that need to be frequently switched, and in safety protection devices, the micro switch can be divided into large, medium, and small. If it is divided according to different needs, it can be divided into waterproof type and normal type.
