US 12,451,307 B1 · Button-switch assembly for AR-VR device

Abstract

A button-switch assembly provides a preloaded force design with an enhanced tactile feel while also providing a non-wobbly (stabilized) configuration and water/dust protection functions. Features of the button-switch assembly include excellent tactile feel through a stack up of a soft rubber layer of a deflection web and a hard PET film shim layer, a consistent pre-loaded push force through use of an angled deflection web, a button flange that minimizes rotation of the button while providing a consistent tactile feel even when the edge of the button is depressed, double sided sealing adhesive layers that seal off the opening in the housing for accepting the button to prevent water/dust from entering the opening, and gluing the button to the rubber deflection web in variable thicknesses to provide a stable tension force to minimize wobble of the button when depressed.

Dependent claims

A button-switch assembly, comprising:

a button;
a housing with a hole adapted to accept the button;
a key mat frame disposed beneath the button, the key mat frame comprising an injection part and a rubber layer, the key mat frame having a pocket centered beneath the button;
a shim actuator placed in the pocket;
a switch beneath the shim actuator;
a printed circuit board beneath the switch;
and
a double sided adhesive between the housing and the key mat frame and between the key mat frame and the printed circuit board to provide a seal that prevents water of dust from accessing the printed circuit board around an outer surface of the key mat frame,
whereby depressing the button deflects the key mat frame and the shim actuator to depress the switch.
