AI Technical Summary
The existing button arm connection structure is prone to stress concentration, which can lead to a stiff, stuck, false or delayed pressing feel, loose or failed connections, shortened service life and increased maintenance costs.
The design employs an elastic support arm, combined with a limiting component on the inner wall of the housing and a guide platform, to ensure stability and elastic reset function during the pressing process, avoid stress concentration, and improve triggering accuracy and durability.
Improve the comfort of pressing, reduce accidental triggering and trigger delay, extend the life of button components, and reduce maintenance costs.
