1. A waterproof micro switch, which is a contact structure with a small contact interval and a snap action mechanism for switching operation with a predetermined stroke and a predetermined force, which is covered by a housing, and the waterproof micro switch has a housing. The drive rod is outside it. With contacts: In the type of waterproof micro switch, the function of the switch is realized by the mechanical switch of the contacts, compared with the semiconductor switch with the characteristics of waterproof micro switch.

2. The external mechanical force acts on the action reed through transmission elements (through pins, buttons, levers, rollers, etc.), and when the action reed moves to the critical point, it will act instantaneously, so that the movable contact is in the action reed. Quickly open or close by means of fixed contacts at the end. When the force on the transmission element is removed, the action reed produces a reverse force, and when the reverse stroke of the transmission element reaches the critical point of the movement of the reed, the reverse action is completed immediately. Micro switches have small contact spacing, short stroke, low power and fast switching speed. The speed of the moving contact is independent of the speed of the transmission element.
