For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] This embodiment aims to provide a new switch module 1 and a push button switch having the same. By using the structure of the new static contact component 13 in the switch module 1, the wiring method of the push button switch is more convenient and efficient.

[0044] like Figure 1 As shown, the button switch is composed of a button head 2, a middle seat 32, a light-emitting module 31 and at least one switch module 1. The switch module 1 may include one or two contact systems, combined with Figure 3 The contact system includes a moving contact component 12 and two groups of stationary contact components 13. The moving contact component 12 moves after the button head 2 is pressed, and contacts or separates from the stationary contact component 13 to turn on or off the circuit.

[0045] The middle seat 32 is connected to the button head 2, the light-emitting module 31 is connected between the top of the switch module 1 and the middle seat 32, and the light-emitting module 31 is provided with a transmission member 311 to transmit pressure to the moving contact component 12 of the switch module 1. The button head 2 is connected to the top of the light-emitting module 31, and is provided with a pressing part 21 and a driven part, and the driven part changes position due to the movement of the pressing part 21 to apply pressure to the transmission member 311. In the electrical automatic control circuit, the button switch is used to manually send a control signal to control a contactor, a relay, an electromagnetic starter, etc.

[0046] Figure 1 and Figure 2 The self-locking push button switch is used as an example for explanation. When the push button switch is pressed for the first time, the switch is turned on and maintained, that is, self-locking. When the switch button is pressed for the second time, the switch is turned off. Figure 2 In the push button switch, more than two switch modules 1 can be connected together for use, and when the button head 2 is pressed, multiple circuits can be controlled to be on and off at the same time.

[0047] Reference Figure 3 , the switch module 1 includes a mounting base 11 and at least one contact system arranged in the mounting base 11, and one contact system includes a group of moving contact components 12 and two groups of static contact components 13. The switch modules 1 shown in the drawings of this embodiment all include two contact systems, one is a normally open contact system, and the other is a normally closed contact system, so as to be able to adapt to different scene requirements. However, the switch module 1 using the static contact component 13 described below in this embodiment can have only one normally open contact system without including a normally closed contact system, or can have two normally open contact systems. Alternatively, the switch module 1 of the static contact component 13 can have only one normally closed contact system without including a normally open contact system; or can have two normally closed contact systems.

[0048] Combination Figure 3 and Figure 4 The moving contact assembly 12 may include a push rod 121, a support frame 122, a tension spring 123, a spring 124 and two moving contact pieces 125, and both ends of the two moving contact pieces 125 are connected with moving contacts 126. Most of the push rod 121 is arranged in the mounting seat 11, and one end is exposed from the mounting seat 11 to contact the transmission member 311 of the light-emitting module 31. The upper end of the support frame 122 is connected to the push rod 121, and the lower end is connected to the upper end of the spring 124, and the lower end of the spring 124 is abutted against the inner bottom wall of the mounting seat 11.

[0049] The middle of the support frame 122 is provided with a long hole 1221 for a tension spring 123 to pass through; and the two sides of the support frame 122 are also provided with slots 1222. Among them, two moving contact pieces 125 are respectively provided on the two sides of the support frame 122, and one end is connected to the tension spring 123, and the other end is abutted in the corresponding slots 1222 of the support frame 122. In this way, when the push rod 121 moves to two different positions, the moving contact piece 125 and its moving contact point 126 also switch between the circuit connection position and the circuit disconnection position.

[0050] Reference Figure 3 and Figures 5 to 8 The static contact assembly 13 includes a contact piece 131 and a spring body 132. One end of the contact piece 131 is connected to a static contact point 133 that cooperates with the dynamic contact assembly 12, and the other end thereof extends to the wiring area of ​​the mounting seat 11; an extension portion 1311 is also formed on the contact piece 131, and the extension portion 1311 includes a hook 13111. The spring body 132 is connected to the contact piece 131 by bending, and at least one end is clamped on the hook 13111, and a strip opening 1321 and a wire pressing portion 1322 and a touch portion 1323 near the strip opening 1321 are formed. The touch portion 1323 drives the wire pressing portion 1322 to elastically deflect under the push of an external force, and the strip opening 1321 serves as a movable space at one end of the extension portion 1311 when the wire pressing portion 1322 deflects.

[0051] Correspondingly, the mounting base 11 is provided with a surrounding plate 111, a wiring hole 112 and an operating hole 113 corresponding to any set of stationary contact components 13. The surrounding plate 111 is provided for the spring body 132 to bend around it, and the wiring hole 112 is provided for the wire 4 to pass through, so that the wire pressing part 1322 of the spring body 132 is pressed against the wire 4. The operating hole 113 is provided for the end of a push rod 5 to extend into and press the contact part 1323 of the spring body 132.

[0052] During the wiring process, one end of the wire 4 can be passed through the wiring hole 112 of the mounting seat 11, and the end of the wire 4 can press the wire pressing part 1322 of the spring body 132 to complete the wiring; or a tool such as a screwdriver can be used to press the touch part 1323 of the spring body 132, so that the wire pressing part 1322 of the spring body 132 can be tilted first, and then the end of the wire 4 inserted by the spring body 132 can be pressed to complete the wiring. In the process of releasing the wire 4, one end of the top rod 5 of a tool such as a screwdriver is inserted into the operating hole 113, and the contact part of the spring body 132 is pressed to deform it, so that the wire 4 can be released. In this way, the wiring operation of the switch module 1 and the push button switch or the operation of releasing the wire 4 is simpler and more efficient.

[0053] For example, refer to Figure 4 There are two upper and lower rows of slots 1222 on both sides of the support frame 122. Figure 3 and Figure 4 The normally open contact system is shown, one end of the moving contact piece 125 is stuck in the lower slot 1222 of the support frame 122, and a moving contact point 126 is arranged on the other end of the moving contact piece 125, and a static contact point 133 is arranged on the bottom surface of one end of the contact piece 131 facing the moving contact point 126. In addition, Figure 5 The normally closed contact system is shown, one end of the movable contact piece 125 is stuck in the upper slot 1222 of the support frame 122, and a movable contact 126 is arranged below the other end of the movable contact piece 125, and a static contact 133 is arranged on the top surface of one end of the contact piece 131 facing the movable contact 126. In this way, the support frame 122 can be used for both the normally open contact system and the normally closed contact system, and has strong versatility, which reduces the manufacturing cost of the switch module 1 and the push button switch as a whole.

[0054] It should be noted that, although the present embodiment describes the switch module 1 by taking the self-locking push button switch as an example, the switch module 1 can also be used for other push button switches such as ordinary push button type, mushroom head type, self-reset type, rotary handle type, indicator light type, light symbol type and key type, that is, all kinds of push button switches having the switch module 1 described in the present embodiment fall within the protection scope of the present application.

In this way, one end of the spring body 132 is engaged with the hook 13111 of the contact member 131.

[0056] In a preferred embodiment of the switch module 1, continue to refer to Figure 3 , Figure 5 and Figure 6 The front side of a curved section of the contact piece 131 is attached to an inner wall of the mounting seat 11, and the back side of the curved section is formed with an extension portion 1311; the extension portion 1311 also includes an insert plate 13112 with a groove 131121, the insert plate 13112 passes through the strip-shaped opening 1321, and the groove 131121 of the extension portion 1311 is plugged into a boss 114 on the inner side wall of the mounting seat 11. In this way, the contact piece 131 is limited by the insertion of the groove 131121 of the contact piece 131 and the internal boss 114 of the mounting seat 11.

[0057] In a preferred embodiment of the switch module 1, continue to refer to Figure 3 , Figure 5 and Figure 6 The spring body 132 is bifurcated at the end of the strip-shaped opening 1321 to form two pairs of actuating portions 1323 and wire pressing portions 1322, and one actuating portion 1323 corresponds to one operating hole 113, and one wire pressing portion 1322 corresponds to one wiring hole 112. Accordingly, the mounting seat 11 is provided with two wiring holes 112 and two operating holes 113 corresponding to a set of static contact components 13. In this way, using a contact member 131 and a set of contact systems including the contact member 131, the on-off control of two circuits can be realized at the same time.

[0058] In a preferred embodiment of the switch module 1, continue to refer to Figure 3 , Figure 5 and Figure 6 The bottom end of the contact member 131 extends to form a support foot 1312, and the support foot 1312 is pressed on the inner bottom wall of the mounting seat 11.
