Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a push button switch. Background Art

[0002] A push button switch is a switch that uses a button to push a transmission mechanism to connect or disconnect the moving contact and the static contact and realize circuit switching. A push button switch is a main control electrical appliance with a simple structure and a wide range of applications. The push button switch in the prior art uses various spring structures to drive the components to reciprocate. However, since the button assembly and the spring are separately set, the spring needs to be pinched during assembly to prevent it from falling, making the installation more cumbersome and easy to fall. Utility Model Content

[0003] Based on the above problems, the utility model provides a push button switch which has a simple structure, stable spring pre-installation and is not easy to fall off.

[0008] The utility model is further configured as follows: a first semicircular ring portion is arranged on the bottom plate, and a second semicircular ring portion is arranged on the cover body at a position corresponding to the first semicircular ring portion; when the base is connected to the cover body, the first semicircular ring portion and the second semicircular ring portion are arranged relative to each other to form a limiting cavity, and the inner diameter of the limiting cavity is adapted to the outer diameter of the spring.

[0009] By adopting the above technical solution, when the cover body is installed on the base, the first semicircular ring portion and the second semicircular ring portion are relatively arranged to form a limiting cavity, so that the bottom of the spring is placed in the limiting cavity, and the front and rear positions of the spring are limited by the limiting cavity, which improves the accuracy of the assembly position. The assembled spring is not easy to shift, and the reliability of the structure is further improved.

[0010] The utility model is further configured as follows: a first mounting hole and a first guide rod are respectively provided at the left and right positions of the upper part of the base; a second guide rod connected to the first mounting hole is provided at the position of the cover body corresponding to the first mounting hole; a first through hole coaxially arranged with the first mounting hole is provided on the second guide rod; the first through hole and the first mounting hole are connected by bolts; a second mounting hole connected to the first guide rod is provided at the position of the cover body corresponding to the first guide rod; a second through hole coaxially arranged with the second mounting hole is provided on the first guide rod; the second through hole and the second mounting hole are connected by bolts.

[0011] By adopting the above technical solution, when the base and the cover body are assembled, the first guide rod corresponds to the position of the second mounting hole and is inserted along its direction, while the second guide rod corresponds to the position of the first mounting hole and is inserted along its direction. After insertion, the base and the cover body are fixed by bolts to complete the connection, which is easy to operate. The first mounting hole and the first guide rod are set on the base, and the second mounting hole and the second guide rod are set on the cover body, which prevents the operator from making assembly mistakes and improves the assembly efficiency.
