The waterproof micro-switch

The waterproof micro-switch is a contact structure having a minute contact interval and a snap-action mechanism, and performs a switching operation with a predetermined stroke and a predetermined force, and waterproof micro switch is covered with a casing and having a drive rod outside thereof. There are contacts: In the type of waterproof micro switch, compared with the semiconductor switch with the characteristics of waterproof micro switch, the function of the switch is realized by the mechanical switch of the contact.

Working principle

The external mechanical force acts on the action reed by the transmission element (by pin, button, lever, roller, etc.), and when the action reed is displaced to the critical point, an instantaneous action is generated, so that the movable contact and the touch at the end of the action reed The point is quickly turned on or off.

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 critical point of the action of the reed, the reverse action is instantaneously completed. The micro switch has a small contact pitch, a short stroke, a small power, and a quick on/off. The speed of the moving contact is independent of the speed of the transmission element.

Application field 

Waterproof micro switches are widely used in a variety of cold, humid, dust and harsh environments. Such as cars, spraying equipment, etc.
