Working principle and classification of waterproof micro switch

1. The waterproof micro switch is an external mechanical force that acts on the action reed through transmission elements (pressing pins, buttons, levers, rollers, etc.) 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. Micro switches are used in electronic equipment and other equipment, such as automatic control and safety protection of frequently changing circuits

2. According to the function: normally open type, normally closed type, conversion type

3. According to the waterproof grade: IP50, IP67

4. According to the volume: small, ultra-small.
