发明名称 LONG TRAVELING BUTTON SWITCH WITH ENHANCED USER FEEDBACK
摘要 LONG TRAVELLING BUTTON SWITCH WITH ENCHANCED USER FEEDBACK A pushbutton switch including a keycap having a keycap top and a keycap plunger, a retaining bezel for guiding the keycap plunger and limiting the displacement thereof, a deformable elastomeric switch button supporting a contact pad, and a printed circuit contact pattern engageable by the contact pad when the switch button is deformed by the downward displacement of the keycap plunger. The deformation of the button switch tactile feedback, while impact of the keycap top against the retaining bezel provides audible feedback. The pushbutton switch is configured to limit the downward displacement of the keycap plunger to avoid excessive force on the printed circuit board.
