Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically a metal push-button switch. Background Technology

[0002] The 8B metal push button switch is a metal push button switch with an opening diameter of 8mm. Due to its small size and reliable performance, it is widely used in home appliances, electronic equipment, lighting equipment, industrial control and other fields, and can be used as a control button, start button, reset button, etc.

[0003] However, existing metal push-button switches still have the following technical problems when in use:

[0004] (1) Most products on the market are too small to be made without lights, but in complex operation panels or poor lighting environments, users have difficulty quickly locating and identifying specific switches.

[0005] (2) Many self-locking switches rely on a combination of multiple parts such as springs and sliders, which are complex in structure, occupy a lot of space, are cumbersome to assemble, and are prone to jamming or failure after long-term use.

[0006] (3) In traditional 8mm switches, the LED circuit and the main circuit (normally open NO, normally closed NC, common terminal COM) are separate, which means that more pins are needed, resulting in an increase in the size of the switch body;

[0007] (4) Traditional switches are fixed by welding, which is not conducive to modular production and later maintenance, and is difficult to disassemble and repair later.

[0008] Therefore, a metal push-button switch is proposed to solve the aforementioned problems. Utility Model Content

[0009] The purpose of this invention is to provide a metal push-button switch to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a metal push-button switch, comprising a light-transmitting cover, an upper pressure spring fixed to the lower end of the inner part of the light-transmitting cover, a contact rod fixed to the bottom of the light-transmitting cover and below the upper pressure spring, a bushing snapped onto the outside of the light-transmitting cover, a heart-shaped part fixed to the side wall of the light-transmitting cover, a locking hook, a side pressure spring, and an elastic sheet fixed inside the bushing, the upper end of the locking hook being fixedly connected to the side wall of the heart-shaped part, the upper end of the side pressure spring being fixedly connected to the lower side of the light-transmitting cover, a base snapped onto the lower end of the bushing, and a C-pin, an LED pin, and a NO pin fixed to the side wall of the bushing, all of which are inserted into the interior of the base;

[0011] An LED light is fixed to the upper end of the base;

[0012] A button is snapped onto the upper end of the light-transmitting cover. After the base, bushing and light-transmitting cover are assembled, an outer shell is snapped onto the outside. A nut is threaded onto the outside of the outer shell, and a socket is sleeved onto the lower end of the outer shell.

[0013] The lower end of the light-transmitting cover is inserted into the inside of the bushing.

[0014] The lower end of the bushing is inserted into the upper end of the base.

[0015] An O-ring is fitted onto the outer surface of the housing above the nut.

[0016] There are two side compression springs in total.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1) This product uses a unique and eye-catching ring-shaped light symbol, allowing users to easily identify it among many switches, thus improving the efficiency and accuracy of human-computer interaction. This advantage is particularly evident in emergency situations or when rapid operation is required.

[0019] 2) This product uses a purely mechanical structure of heart and lock hook to achieve the function of "press to lock, press again to unlock" with the fewest parts. The simpler the structure, the lower the failure rate, the more frequent the operation, and the longer the service life.

[0020] 3) The ingenious design of the circuit and structure of this product allows one pin to be used for two functions, directly reducing one physical pin. This enables complex functions to be implemented in an extremely small size of 8mm, greatly saving the layout space of the switch body. Reducing the number of pins means that the difficulty and workload of soldering and wiring are reduced.

[0021] 4) This product uses connectors, so installation is as simple as inserting the connector into the switch; no soldering is required. This greatly simplifies the assembly process on the production line, improves production efficiency, and when the switch is damaged or needs to be upgraded, it can be replaced simply by unplugging the connector, achieving "plug and play" and greatly reducing the difficulty, time, and cost of after-sales maintenance.
