The embodiment aims at providing a novel light-emitting module 1 and a button switch with the same, so that the wiring mode of the button switch is more convenient and efficient.

The button switch with lamp shown in fig. 1 is formed by connecting a button head 2, a middle seat 3, a switch module 4 and a light-emitting module 1. In this embodiment, the push-button switch uses one light emitting module 1 and four switch modules 4.

The middle seat 3 is connected to the button head 2, the light-emitting module 1 and the switch module 4 are connected to the other end of the middle seat 3, and the middle seat 3 is provided with a transmission member for transmitting pressure to the movable contact assembly of the switch module 4. The button head 2 is provided with a pressing portion and a driven portion, and the driven portion is changed in position by the movement of the pressing portion to apply pressure to the driver. In the electric automatic control circuit, a push button switch is used to manually issue a control signal to control a contactor, a relay, an electromagnetic starter, and the like.

By the illumination of the illumination module 1, a bright light is visible at the button head 2 to indicate the operating state of the button switch. The switch module 4 may include one or two sets of contact systems, where the contact systems include a movable contact component and two sets of static contact components, and the movable contact component and the static contact component contact to conduct a circuit or the movable contact component and the static contact component separate to disconnect the circuit after the button head 2 is pressed.

It should be noted that, although the present embodiment is described taking the push-button switch shown in fig. 1 as an example, the light emitting module 1 of the present embodiment may be used in other types of push-button switches.

Referring to fig. 2 to 4, the light emitting module 1 includes a housing assembly 11, a circuit board 121, a lamp bead 122, two contacts 13 and two reed bodies 14.

Referring to fig. 3, a middle cavity and two side cavities located at two sides of the middle cavity are formed in the housing assembly 11, and two opposite sides thereof are provided with a wire connection hole 1101 and an operation hole 1102 which are communicated with the corresponding side cavities, and a winding post 112 is further disposed in each side cavity. The circuit board 121 is clamped in the middle cavity, and a lamp bead 122 is electrically connected to the circuit board.

Referring to fig. 2 and 3, a contact 13 is disposed in a side cavity, the contact 13 is bent, one end of the contact 13 extends to an inner end of the wiring hole 1101 on a corresponding side, a boss 131 is disposed on an inner side of the contact 13, the other end of the contact 13 extends to be electrically connected to the circuit board 121, and a hook 132 is disposed on an inner side of the contact 13.

A reed body 14 is connected to a contact 13, a connecting port 141 at one end of the reed body 14 is connected to a hook 132, the middle of the reed body 14 is bent around the post 112, the end of the reed body 14 abuts against the boss 131, and the operation hole 1102 is opposite to an elastic touch part 143 of the reed body 14.

In the wiring process of the light emitting module 1, the rigid conductor with the insulating skin stripped or the flexible conductor with the wiring sleeve can be directly inserted into the clamping part between the tail end of the reed body 14 and the contact piece 13 without using tools, and the connection can be directly completed. When the wire is separated from the light emitting module 1, the wire can be loosened by pushing the elastic touch portion 143 of the compression spring sheet 14 through the operation hole 1102 by a tool. Thus, the wiring and the wire-stripping processes of the light-emitting module 1 are more efficient.

For example, referring to fig. 2 and 5, the housing assembly 11 may include a housing plate 113 and a cover plate 114, wherein the housing plate 113 has a recess for forming a middle cavity and a side cavity, and the cover plate 114 is coupled to the housing plate 113 and compresses the circuit board 121 and the contacts 13 within the housing plate 113. For example, corresponding lugs or ribs may be provided on the cover plate 114 to cooperate with the housing plate 113 to clamp the circuit board 121 and the contacts 13.

Preferably, with continued reference to fig. 2 and 5, the shell plate 113 is provided with a connection groove 1131, the cover plate 114 is provided with a connection rib 1141, and the connection groove 1131 and the connection rib 1141 can be connected by ultrasonic welding.

Preferably, a guide tube 111 is provided outside one end of the housing assembly 11, and the light emitting portion of the lamp bead 122 extends to the guide tube 111. In this way, the light can be better focused on the button head 2 of the push button switch.

Preferably, referring to fig. 2 and 3, two test holes 1103 may also be provided on the housing assembly 11, with one test hole 1103 facing a corresponding one of the contacts 13. In this way, the plug of the external multimeter can be inserted into the test hole 1103 to determine whether the light emitting module 1 can be normally electrified.

In a preferred embodiment, referring to fig. 4, the inner side of the contact 13 may be formed with a spacer 133. Accordingly, the other side of the spring body 14 away from the connection port 141 thereof may be bifurcated to form two support legs 142, and one support leg 142 is located at one side of the partition plate 133. Wherein, two wiring holes 1101 and two operation holes 1102 are provided on the same side of the housing assembly 11. Thus, the light emitting module 1 can form two paths to meet the indication requirements under different use scenes. For example, different indications of a long bright and a flashing light.

Therefore, the push button 15 has a certain movement range, and the push button 15 cannot be separated from the light-emitting module 1 and cannot accidentally fall into the light-emitting module 1. When the lead is detached from the light emitting module 1, the elastic touch part 143 of the pressure spring sheet 14 can be pushed only by pressing the push button 15, so that the lead is released.

In a preferred embodiment, referring to fig. 3, two sides of the circuit board 121 are respectively provided with a socket, and one end of one contact 13 extends into a corresponding socket, and the contact 13 and the circuit board 121 may be electrically connected by soldering.

In addition, in another embodiment, referring to fig. 6, two conductive spring plates 123 may be disposed on the circuit board 121, and the conductive spring plates 123 are electrically connected to the circuit board 121. For example, the conductive spring 123 has a good compression and expansion effect, and can be fixed on the circuit board 121 by reflow soldering. Correspondingly, the contact 13 is further provided with a pressing plate 134, and the pressing plate 134 presses the elastic sheet 123 to perform conductive connection. For example, the conductive spring 123 may have a bottom plate 1231 connected to the circuit board 121 and an arc spring arm 1232 bent to the upper side of the bottom plate 1231.

The application relates to the field of low-voltage electrical equipment, in particular to a light-emitting module 1 and a button switch. The light emitting module 1 includes a housing assembly 11, a circuit board 121, a lamp bead 122, two contact members 13, and two reed bodies 14. In the wiring process of the light-emitting module 1, the rigid conductor stripped of the insulating skin can be directly inserted into the clamping part between the tail end of the reed body 14 and the contact piece 13 to complete the connection. When the wire is separated from the light emitting module 1, the wire can be loosened by pushing the elastic touch portion 143 of the compression spring sheet 14 through the operation hole 1102 by a tool. Thus, the wiring and the wire-stripping processes of the light-emitting module 1 are more efficient.
