AI Technical Summary
The prior art does not increase the contact area of the contact point and the upper cover and reduce the stroke, resulting in unresponsive buttons and inconsistent pressing feel anywhere on the plane, or the pressing is unresponsive.
A foot switch is designed, by setting a spring between the upper cover and the lower cover, and increasing the contact area between the upper cover and the contact plate, reducing the pressing stroke, and using the spring force to achieve rapid reset, while installing a baffle at the bottom of the upper cover to limit the position.
It effectively solves the problems of non-response buttons and inconsistent hand feel, ensuring that the force and reset are consistent when pressed at 360°, improving the user experience.
