Description

Technical Field

[0001] This utility model belongs to the field of switches, and in particular relates to a metal push button switch. Background Technology

[0002] Combination metal push-button switches typically combine the upper part of a metal button with a tactile switch. The button assembly on the upper part of the metal button is used to press the button on the tactile switch to open or close the circuit. Traditionally, the upper part of the metal button and the tactile switch are usually fixedly connected and cannot be disassembled. If the tactile switch is damaged, the entire switch must be replaced, which is costly and inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a modular metal push-button switch that is easy to disassemble, assemble, and maintain.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a base, a metal shell disposed on the base, and a button assembly disposed within the metal shell. The lower end of the base is disposed on a switch mounting base. The switch mounting base is provided with a tactile switch and hanging slots are provided on both sides corresponding to the tactile switch. Hooks connected to the hanging slots are provided on both sides of the base. The button assembly includes a button cap and a positioning ring disposed at the lower end of the button cap. A push rod for pressing the button of the tactile switch is provided at the lower end of the positioning ring.

[0005] The button assembly includes an illuminated PCB board with terminals soldered on both sides. The lower end of each terminal is located in a positioning groove inside the hook and has a socket. The switch mounting base has pins on both sides, and the upper end of each pin is inserted into the socket.

[0006] It also includes a self-locking mechanism, which includes a heart-shaped groove on the side of the push rod and a spring plate on the base, wherein the spring plate is provided with a locking rod that cooperates with the heart-shaped groove.

[0007] The lower end of the cap is provided with a conical sealing ring.

[0008] The bottom of the switch mounting base is provided with a buffer spring, and the buffer spring is provided with a support post that abuts against the tactile switch.

[0009] The advantages of this utility model of combined metal push button switch are as follows: the tactile switch and the upper part of the metal button are very convenient to disassemble and assemble. Simply install the tactile switch into the switch mounting base and then insert the hook into the hanging slot.

[0010] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0019] Reference Figure 1-8 As shown, the present invention relates to a combined metal push-button switch, comprising a base 1, a metal housing 2 disposed on the base 1, and a push-button assembly 3 disposed within the metal housing 2. The lower end of the base 1 is mounted on a switch mounting base 4, which houses a tactile switch 5, and has hanging grooves 6 on both sides corresponding to the tactile switch 5. Hooks 7 connected to the hanging grooves 6 are provided on both sides of the base 1. The push-button assembly 3 includes a button cap 8 and a positioning ring 9 at the end of the button cap 8. The positioning ring 9 is slidably mounted within the cavity of the base 1 and adapts to the cavity to ensure the stability of the button cap 8 when pressed. A push rod 11 is provided at the lower end of the positioning ring 9 for pressing the button 10 of the tactile switch 5. The reset of the push rod 11 after pressing is accomplished by the tactile switch 5.

[0020] Preferably, the button assembly 3 includes an illuminated PCB board 12. Terminal blocks 13 are soldered to both sides of the illuminated PCB board 12. The lower ends of the terminal blocks 13 are located in the positioning groove 14 inside the hook 7, and have insertion ports 15 at their lower ends. The switch mounting base 4 has pins 16 on both sides. The upper ends of the pins 16 are inserted into the insertion ports 15, and the lower ends of the pins 16 are used to connect to an external power cord. When the hook 7 is hooked into the hanging groove 6, the upper ends of the pins 16 are also inserted into the insertion ports 15, thereby achieving a quick connection with the illuminated PCB board 12.

[0021] Preferably, it also includes a self-locking mechanism 17, which includes a heart-shaped groove 18 on the side of the push rod 11 and a spring piece 19 on the base 1. The spring piece 19 has a locking rod 20 that cooperates with the heart-shaped groove 18. This structure allows for self-locking after the push rod 11 is pressed, thus enabling the tactile switch 5 to be pressed continuously. The self-locking mechanism 17 is traditionally known as a heart-shaped lock structure, and its working principle is well-known technology and will not be described in detail here.

[0022] Preferably, the lower end of the button cap 8 is provided with a conical sealing ring 21 to achieve waterproofing of the switch. At the same time, the elasticity of the conical sealing ring 21 can be used to quickly reset the button cap 8 after it is pressed.

[0023] Preferably, the bottom of the switch mounting base 4 is provided with a buffer spring 22, and the buffer spring 22 is provided with a support post 23 that abuts against the tactile switch 5, so that the tactile switch 5 has a buffering effect when pressed, and also plays a positioning role for the tactile switch 5.

[0024] The above description is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
