1. 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.
