Abstract
A switch device includes a first rubber dome, a second rubber dome, and a slider disposed on the first rubber dome and the second rubber dome. The slider presses the upper surface of the first rubber dome, causing deformation of the first rubber dome when the slider is moved toward the first and second rubber domes, and presses the upper surface of the second rubber dome, causing deformation of the second rubber dome when the slider is further moved toward the first and second rubber domes in a state in which the first rubber dome is subjected to the deformation. A thick portion is formed on each side of the second rubber dome so as to increase the thickness on the each side of the second rubber dome. Each side of the second rubber dome is in a direction in which the first and second rubber domes are aligned.
Claims6
A switch device comprising:
- a rubber dome sheet including:
- a base;
- a first rubber dome protruding from the base and forming a first upper portion having a first upper surface;
- and
- a second rubber dome protruding from the base and forming a second upper portion having a second upper surface;
- and
- a slider disposed on the first upper surface of the first rubber dome and the second upper surface of the second rubber dome, wherein
- the slider presses the first upper surface of the first rubber dome, causing deformation of the first rubber dome in a case where the slider is moved toward the first rubber dome and the second rubber dome, and the slider presses the second upper surface of the second rubber dome, causing deformation of the second rubber dome in a case where the slider is further moved toward the first rubber dome and the second rubber dome in a state in which the first rubber dome is subjected to the deformation, and
- a thick portion is formed at a side wall of the second rubber dome between the second upper portion and the base and positioned along an imaginary line between a center of the first rubber dome and a center of the second rubber dome, said thick portion having a thickness that is greater than that of other portions of the side wall that are not positioned along the imaginary line.
