Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a multi-way switch. Background Art

[0002] A tactile switch is an electronic switch, belonging to the category of electronic components, also known as a push-button switch. It first appeared in Japan [referred to as: sensitive switch]. When in use, it presses in the operation direction of the switch to meet the condition of the operating force, and the switch function is closed and connected. When the pressure is withdrawn, the switch is disconnected. Its internal structure realizes on-off by the force change of a metal elastic sheet.

[0003] For example, the Chinese patent with the publication number CN215299103U proposes a multi-way adjustment switch. Since the pressing cover of this component is pressed and controlled in any direction of the cross direction, it can ensure single-direction operation and non-operation in other directions, avoiding misoperation and wrong pressing. At the same time, it also avoids multiple tactile switches working simultaneously, improving the use and experience effect. The middle button for the fifth-direction control in the center has a different position from the other four directions and is pressed up and down, with different handfeel and pressing methods, so it can also be significantly distinguished from the other four directions to avoid misoperation and wrong pressing. It can be selected and installed according to different appearance, two-way, four-way or five-way and other different requirements for different customers. At the same time, the replacement is very simple, and it is not easy to misoperate and is more convenient to operate and use after adopting different configurations, improving the actual experience effect of users. It is most suitable for the field of automobile seat modification, and can be selected according to the different requirements of the number of switch directions of the control switch during the selection and installation of electric adjustment, ventilation, heating, massage, etc. of the seat during customer modification (common two-way, four-way and five-way controls).
