Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The following describes an implementation of the push switch according to the present invention in detail with reference to fig. 1 to 5. According to an embodiment of the present invention, a push switch is provided, which has a base 100, a terminal 200 and a fastener 300; the terminal block 200 is used for mounting a stationary contact of a contact switch or a circuit board of a signal switch in the base 100, and the fastener 300 is used for connecting the terminal block 200 with an external conductor.

Specifically, the base 100 is provided with a mounting hole 101 penetrating the inside and outside of the base 100; the terminal 200 is inserted into the mounting hole 101, and the bottom surface of the terminal 200 is recessed upwards to form a counter bore 201, and the counter bore 201 is suitable for being connected with a fastener 300 so that the terminal 200 is connected with an external conductor. Thus, foreign objects cannot enter the switch through the counterbore 201, i.e., into the base 100. The terminal 200 is different from a traditional through hole structure through the design of the counter bore 201, so that external foreign matters can be prevented from entering the switch, the protection capability of the switch is ensured, the phenomena of short circuit and the like are avoided, and the service life of the switch is prolonged.

The terminal 200 is inserted into the mounting hole 101 from the inside of the base 100, is tightly fitted in the base 100, and may be pressed by a cover or the terminal 200 may be riveted to the base 100.

According to some embodiments of the present invention, the top of the terminal 200 is connected to the circuit board 400; to accommodate the use of the circuit board 400, a movable brush may be disposed within the base 100 such that the brush and the circuit board 400 form a signal switch.

Optionally, in conjunction with fig. 3, the post 200 and the circuit board 400 are electrically connected through the elastic element 500. The elastic member 500 ensures that the circuit board 400 is always in contact with the brush. Specifically, the periphery of the terminal 200 is provided with a step 202, the elastic element 500 is sleeved on the terminal 200, one end of the elastic element abuts against the step 202, and the other end of the elastic element abuts against the circuit board 400. Further, the elastic member 500 may adopt a compression spring structure.

Of course, in other examples, in conjunction with fig. 4, the post 200 and the wiring board 400 may be electrically connected by riveting.

Referring to fig. 2, in order to ensure the reliability of the circuit board 400, two terminals 200 may be used for supporting the circuit board; correspondingly, two mounting holes 101 may be provided on the base 100 for mounting two terminals 200. In addition, the mounting hole 101 may be provided at the bottom of the base 100; thus, the circuit board 400 can be horizontally mounted, so that the brush can horizontally slide on the circuit board 400.

Further, referring to fig. 1 and 6, the push switch may be fastened to the base 100 through the cover 600 to seal the inside of the switch. After the cover 600 and the base 100 are fastened, the bump 601 of the pillar in the cover 600 can be inserted into the limiting hole 401 of the circuit board 400, and then the supporting surface of the bump 601 is pressed on the circuit board 400, so as to firmly fix the circuit board 400 on the terminal 200.

According to some embodiments of the present invention, the terminal 200 may be connected to the stationary contact 700, and a movable contact may be provided in the base 100 to cooperate with the stationary contact 700, so that the movable contact and the stationary contact 700 form a contact switch.

Alternatively, the terminal 200 is L-shaped, and the stationary contact 700 is connected to an inner sidewall of the L-shaped terminal. In this way, the movable contact can be contacted with or separated from the fixed contact 700 when moving in the horizontal direction, and the contact switch is turned on or off. Of course, to match the use of the push switch, two movable contacts are usually provided, two stationary contacts are also provided, and two corresponding terminals 200 can be provided.

Other configurations of the push switch according to embodiments of the present invention may employ existing structures, and are not described in detail herein.
