ABSTRACT:
A key sensing device comprises a first conductive contact and a second conductive contact spaced from one another by a low-force spacer element which includes a low-force aperture disposed between the first conductive contact and the second conductive contact. A third conductive contact and a fourth conductive contact are spaced from one another by a high-force spacer element which includes a high-force aperture disposed therebetween. The low-force aperture and the high-force aperture are configured to be aligned with a keyboard key so that a pressing of the keyboard key with a sufficient force causes contact between the first conductive contact and the second conductive contact through the low-force aperture and contact between the third conductive contact and the fourth conductive contact through the high-force aperture. The low-force aperture is larger in size than the high-force aperture.
