Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, the embodiment of this application provides a BUTTON switch that sealing grade is high, and this BUTTON switch BUTTON that sealing grade is high includes ebonite shell 1, the up end of ebonite shell 1 is provided with the opening, be provided with soft glued membrane 2 in the opening, be provided with ebonite BUTTON 3 in the soft glued membrane 2, the hardness that the shell 1 was used for guaranteeing to the outside adoption ebonite, middle soft glued membrane 2 is the movable part, and innermost ebonite BUTTON 3 is used for gaining in strength for this BUTTON switch's wearing and tearing are little, long service life.

The contact surface of ebonite shell 1 and flexible glue membrane 2 sets first inclined plane into, the part of flexible glue membrane 2 and ebonite shell 1 contact sets the second inclined plane into, first inclined plane and the contact of second inclined plane for increase ebonite shell 1 and flexible glue membrane 2's area of contact has strengthened tensile ability, prevents that water or steam from entering into in the ebonite button 3.

The hard glue can be PBT, ABS, PA, PP or PC, the soft glue can be TPE, TPU or TPS, and the soft glue film 2 in the embodiment is TPE.

On the basis, the edge of the soft rubber film 2 is provided with the reverse buckle 4, the reverse buckle 4 is in close contact with the hard rubber shell 1, the contact area between the hard rubber shell 1 and the soft rubber film 2 is increased, and the tensile strength is enhanced.
