Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat switches, in particular to a vehicle seat switch with an elastic arm structure. Background Art

[0002] A car seat switch is a device used to adjust and control the position and function of a car seat. Modern car seat switches usually have multiple functions, including adjusting the front and rear position of the seat, backrest angle, height, lumbar support, etc. Car seat switches generally include a button assembly, a slider, a switch upper shell, a toggle switch, a two-way toggle switch, a circuit board assembly, and a switch bottom plate. By pushing the button assembly left and right or front and back, the slider is driven to move between the toggle switch or the two-way toggle switch shell and the switch upper shell. The toggle switch is connected to the corresponding circuit board assembly to realize the corresponding function. In actual use, it is found that after frequent movement of the slider, it is difficult to completely reset the slider, so that the slider cannot maintain dynamic balance, resulting in the slider being stuck and eventually damaged. The service life of the seat switch is greatly reduced. At the same time, the overall pushing action needs to be further optimized, and improvements are made in this regard. Utility Model Content
