Detailed Description

The following describes the embodiments of the present application further with reference to the accompanying drawings. It should be noted that the descriptions of these embodiments are used to help understand the present application, but are not meant to limit the present application. In addition, technical features described below in the various embodiments of the present application may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the embodiment of the present application provides a tact switch 100, and the tact switch 100 specifically includes a switch housing 110 having an assembly space, a button assembly 120, and a plurality of switch pins 130. The button assembly 120 is assembled in the assembling space, and has a button member 121 protruding from the first surface of the switch housing 110. The switch pins 130 are vertically protruded on the second surface of the switch base 110, and one ends of the switch pins 130 extend into the assembly space to movably abut against the connecting piece 122 of the button assembly 120. The two opposite sides of the switch base 110 are also respectively protruded to form a supporting hanging table 10, and the two supporting hanging tables 10 are relatively located at two sides of the button member 121.

It should be understood that the switch housing 110 is mainly used to implement assembly and fixing of the whole components of the tact switch 100, and may have any structural shape, including but not limited to a cylinder or a cube as shown in fig. 1 and 2, and may also have any implementation form, including but not limited to a unitary structure or a detachable structure as shown in fig. 1 and 2. The above-mentioned button assembly 120 is mainly used for implementing the tact switch control function of the tact switch 100, and since the improvement point of the embodiment of the present application is not to change the specific implementation structure of the button assembly 120, it can be considered that the specific implementation structure of the button assembly 120 is not different from that of the existing tact switch, and the button assembly may also specifically include a button member 121 and a connecting member 122, where the button member 121 is in power connection with the connecting member 122, so that the connecting member 122 is abutted to connect with the plurality of switch pins 130 under the acting force of the button member 121.

Thus, the tact switch 100 of the embodiment of the present application may form a plugboard structural design, so that the tact switch 100 may be used for welding a bonding wire and a plugboard of an upper PCB, that is, it may be directly used for other mechanisms to match, so as to reduce the cost of the original SMT patch type tact switch to be provided with the PCB, and further, the tact switch 100 may be well applied in a device requiring frequent replacement or inconvenient use of SMT technology. Meanwhile, the two support hanging platforms 10 can play a role in well supporting and fixing the whole tact switch 100 when the PCB board plugboard on the tact switch 100 is welded for use.

In some examples, as shown in fig. 1 and 2, the switch base 110 includes a base 111 and a main cover 112 having a receiving slot, and the base 111 covers an opening of the receiving slot to form an assembly space. It will be appreciated that the two support stands 10 may be specifically formed on the main cover 112 in a protruding manner. In this way, through the detachable structural design between the base body 111 and the main cover body 112, the user can conveniently open the assembly space at any time, so as to perform corresponding disassembly and maintenance on the tact switch 100. Further, the two side walls of the base body 111 are detachably and fixedly connected with the corresponding inner walls of the accommodating groove body through the fastening structure 11, so that a user can conveniently open the assembly space at any time.

In some examples, as shown in fig. 1 and 2, the plurality of switch pins 130 are protruding on a side surface of the base 111 away from the bottom wall of the accommodating groove, and one ends of the two switch pins 130 extend to a side surface of the base 111 facing the bottom wall of the accommodating groove, and protruding on a side surface of the base 111 facing the bottom wall of the accommodating groove, so as to movably abut against the connecting piece 122 of the button assembly 120, so that the fixed assembly of the plurality of switch pins 130 can be realized through the base 111.

In some examples, as shown in fig. 1 and fig. 2, the two support hanging tables 10 are respectively concavely provided with different plugging guide grooves 12, and the opening direction of each plugging guide groove 12 is the same as the protruding direction of the plurality of switch pins 130 on the second surface of the switch base 110. Therefore, when the PCB board plugboard on the tact switch 100 is welded, the tact switch 100 can be more accurately spliced and fixed on the PCB board by the arrangement of different splicing guide grooves 12 and the cooperation of the guide posts of the PCB board.
