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] A metal push-button switch is a switch that uses a button to actuate a transmission mechanism, causing the moving contact to connect or disconnect with the stationary contact, thus switching the circuit. The structure of a traditional metal push-button switch includes: a base, a bushing on the upper part of the base, and a metal housing outside the bushing. A set of wiring pins is located on the base, and a button is located on the top of the housing. A push rod is connected to the lower end of the button. A stationary contact is located at the top of the wiring pins, and a moving contact that engages with the stationary contact is located at the lower end of the push rod. To achieve a normally closed state, a locking mechanism (self-locking structure) is usually included inside the switch. The locking mechanism mainly consists of a locking groove, a locking plate, and a locking hook. A disadvantage of traditional metal push-button switches is their low internal space utilization; for example, a traditional 19mm metal push-button switch can only be made in a single color.

[0020] Reference Figure 1-6As shown, the small-volume metal push-button switch of this utility model includes a base 1, an inner shell 2 disposed on the upper end of the base 1, and a metal outer shell 3 disposed outside the inner shell 2. A set of wiring pins 4 are provided on the base 1, and a contact mechanism 5 is provided on the wiring pins 4. The contact mechanism 5 consists of a stationary contact and a moving contact.

[0021] The inner housing 2 is equipped with a transmission mechanism 6, and the metal outer shell 3 is equipped with a button 7. The button 7 pushes the transmission mechanism 6 to connect or disconnect the contact mechanism 5. The base 1 has clearance grooves 8 on both sides and a connecting post 9 integrally formed with the middle part of the clearance grooves 8. The connecting post 9 has a first hook 10 on both sides and a second hook 11 on the front. The inner housing 2 has a first elastic buckle 12 on both sides that connects to the first hook 10, and the metal outer shell 3 has a first hanging groove 13 that connects to the second hook 11.

[0022] Preferably, the transmission mechanism 6 includes a push rod 14 and a pressing ring 15 integrally formed on the top of the push rod 14, the pressing ring 15 being provided with a second elastic buckle 16. The bottom of the button 7 is provided with a second hanging groove 17 that connects to the second elastic buckle 16. Through the cooperation between the second elastic buckle 16 and the second hanging groove 17, a quick connection between the transmission mechanism 6 and the button 7 can be achieved.

[0023] Preferably, the push rod 14 is provided with a locking groove 18 and a locking rod 19 that cooperates with the locking groove 18. The locking rod 19 is provided with a spring 20. The connecting post 9 is provided with a slot 21 for fixing the spring 20. The base 1 is provided with a guide groove 22 for installing the push rod 14. Through the above structure, the space of the connecting post 9 and the base 1 is reasonably utilized to realize the assembly of the spring 20 and the push rod 14. The locking rod 19, the spring 20 and the locking groove 18 form a self-locking mechanism of the switch (i.e., a heart-shaped lock structure). This self-locking mechanism is a known technology and will not be described in detail here.

[0024] Preferably, the connecting post 9 has a guide hole 23 on the other side of the guide groove 22, and the pressing ring 15 has a guide post 24 that cooperates with the guide hole 23. The cooperation between the guide post 24 and the guide hole 23 improves the stability of the sliding of the push rod 14.

[0025] Preferably, the base 1 has two lamp feet 25 on each side, and an LED circuit board 26 is welded to the top of each lamp foot 25. Through improvements to the mounting structure of the base and inner shell, the base 1 has sufficient space to install more lamp feet 25, thus enabling the production of three colors.

[0026] Preferably, the pressing ring 15 has a first light-transmitting surface 27 between it and the second elastic buckle 16, and the top of the button 7 has a second light-transmitting surface 28. Through the first light-transmitting surface 27 and the second light-transmitting surface 28, the light from the LED circuit board 26 can be better refracted.

[0027] Preferably, the inner shell 2 has circumferentially arranged retaining ribs 29 integrally formed on its sidewall, which are used to fix it to the metal outer shell 3, thereby achieving a stable connection between the inner shell 2 and the metal outer shell 3.

[0028] Preferably, a sealing ring 30 is provided between the button 7 and the inner housing 2 to achieve the anti-switching performance.
