Background

The touch switch is a common switch component in electrical equipment and has the characteristics of sensitive action, high parameter precision, small volume and the like. The structure of the touch switch is as disclosed in patent document, and a manufacturing method (application number: 2016610339696. X) thereof includes: an insulating layer, the lower surface of which is covered with a non-conductive substance; a conductive member provided over the insulating layer; a metal contact piece which is arranged in the accommodating space and is provided with a convex part in the middle; an operation pressing point which concentrates the force of the external force pressing the switch on the middle part of the metal contact piece; and the protective layer is arranged on the insulating reinforcement layer and fixes the operation pressing point and the metal contact piece in the accommodating space. The protective layer in the touch switch has limited buffering and damping effects, the touch switch belongs to a device with a relatively precise structure, and when the touch switch is impacted, the touch switch is easy to damage, and the service life of the touch switch is influenced.

The second micro switch and the third micro switch are respectively provided with a contact, and then the contacts are pressed by the movable contact piece to realize the connection or disconnection of the first micro switch and the third micro switch. In the mechanism, though the movable contact piece is arranged to press the contact of the micro switch, the contact can be prevented from being directly impacted, but the mechanism has some defects: when a harder movable contact piece is adopted, the movable contact piece is difficult to form a buffering effect, and the impact force born by the movable contact piece can be directly transmitted to a contact, so that the micro switch is damaged; when the soft movable contact is adopted, although the movable contact can be well deformed to form buffer when being impacted, the micro switch is effectively protected, the soft movable contact can cause delay and sensitivity reduction to influence the usability of the touch switch because the movable contact is required to be greatly deformed when being pressed to drive the contact to move. At present, for the problem, the conventional technical means is to install a spring on a touch switch to support a movable contact, and as disclosed in patent literature, a power type micro switch (application number: 201310386666.0) is provided with a spring between a button and a push rod, so that when the button is impacted, a good damping effect can be achieved through deformation of the spring, and a switch element is effectively protected.
