In view of the above, the technical solution adopted by the present application to solve the technical problem is: the utility model provides a heavy board dabs switch, includes apron, base, button, reed and pin, switch mounting is on the PCB board, its characterized in that: the base be provided with spacing pin portion and button portion, spacing pin portion links to each other with the button portion is perpendicular to become L shape, it is provided with the rectangle recess that is used for fixed switch to be located the slope of base bottom, the rectangle recess is located between spacing pin portion and the button portion, be provided with circular recess in the button portion, be provided with circular reed in the circular recess, circular reed and circular recess shape looks adaptation, circular reed top is provided with and is used for dustproof and waterproof's rubber membrane, the rubber membrane top is provided with the button, the button top is provided with the apron, the button runs through the apron and extends to outside the apron, the apron cladding is in the base upper end, spacing pin portion lower extreme both sides are provided with the pin.

The utility model discloses still further set up to, spacing pin portion wide in button portion, button portion one side is provided with the stopper, form the spacing recess that is used for inserting the PCB board between stopper and the spacing pin portion, and be provided with one-way sawtooth on the corresponding inner wall of spacing recess both sides.

The utility model is further arranged in that the circular groove is internally provided with a circular contact point.

The utility model is further arranged in that the round reed is in a shape of a spherical crown protruding downwards.

The utility model also further sets up to, the rectangle recess in be provided with a plurality of fixed orificess that are used for fixing.

Has the advantages that:

1. spacing pin portion links to each other perpendicularly with the button portion and becomes the setting of L shape, has transferred the side of PCB board with partly size of switch, only keeps pin portion just to weld on the PCB board, and the PCB board vacates the dedicated breach position of switch for the switch simultaneously, makes things convenient for the switch to place and also satisfies pleasing to the eye clean and tidy needs, has reduced the distance between switch and the PCB board, has satisfied the demand of market to frivolous switch.

2. The limiting grooves arranged on the two sides of the switch base facilitate the installation of the switch, the inner wall of each limiting groove is provided with one-way sawteeth, the one-way sawteeth can be used for a PCB and can only be inserted into the PCB to be extracted out, the switch is well stabilized on the PCB, the switch is prevented from falling due to instable installation when not welded, the switch can also be separated from the PCB when needing to be extracted out through transverse movement, and the switch is convenient to use and very simple.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.

As shown in fig. 1-4, the switch comprises a cover plate 1, a base 2, a button 4, a reed and pins 5, the switch is mounted on a PCB 7, the base 2 is provided with a limit pin 21 and a button 22, the limit pin 21 and the button 22 are vertically connected to form an L-shape, a rectangular groove 6 for fixing the switch is obliquely arranged at the bottom of the base 2, the rectangular groove 6 is arranged between the limit pin 21 and the button 22, a circular groove 24 is arranged in the button 22, a circular reed 3 is arranged in the circular groove 24, the circular reed 3 is matched with the circular groove 24 in shape, a rubber film 25 for dust and water prevention is arranged above the circular reed 3, the button 4 is arranged above the rubber film 25, the cover plate 1 is arranged above the button 4, the button 4 penetrates through the cover plate 1 and extends out of the cover plate 1, the cover plate 1 is wrapped at the upper end of the base 2, the pins 5 are arranged at two sides of the lower end of the limit pin 21, the limiting pin part 21 is wider than the button part 22, a limiting block 26 is arranged on one side of the button part 22, a limiting groove used for being inserted into the PCB 7 is formed between the limiting block 26 and the limiting pin part 21, unidirectional sawteeth 28 are arranged on the corresponding inner walls of the two sides of the limiting groove, a circular contact point 23 is arranged in the circular groove 24, the circular reed 3 is in a spherical crown shape protruding downwards, and a plurality of fixing holes 61 used for fixing are arranged in the rectangular groove 6.
