Waterproof type switch and electronic device
A waterproof type switch includes: a waterproof sheet including a flat portion and a side wall portion disposed around the flat portion, an upper portion of the side wall portion coupled to an edge portion of the flat portion; a switch disposed below the flat portion; and an electronic component coupled to an upper surface of the flat portion, the electric component being used as a key top, wherein the waterproof sheet includes a rubber and a reinforcing plate including a first reinforcing plate disposed on the upper surface of the flat portion and coupled to the electric component.
1. A waterproof type switch comprising:
a waterproof sheet including a flat portion and a side wall portion disposed around the flat portion, an upper portion of the side wall portion coupled to an edge portion of the flat portion;
a switch disposed below the flat portion; and
an electronic component coupled to an upper surface of the flat portion, the electric component being used as a key top,
wherein the waterproof sheet includes a rubber and a reinforcing plate including a first reinforcing plate disposed on the upper surface of the flat portion and coupled to the electric component,
wherein a hole is formed so as to pass through the flat portion and the reinforcing plate.
2. The waterproof type switch according to claim 1 , wherein the water proof sheet is formed by integrating the rubber and the reinforcing plate.
3. The waterproof type switch according to claim 1 , wherein the waterproof sheet includes a flange portion extending outward from a lower end of the side wall portion, and a second reinforcing plate is disposed on an upper surface the flange portion.
4. The waterproof type switch according to claim 1 , wherein upon pressing the electronic component, the side wall portion of the waterproof sheet is deformed and a lower surface of the flat portion makes contact with the switch.
5. The waterproof type switch according to claim 1 , wherein the electronic component includes a biometric authentication module.
6. The waterproof type switch according to claim 1 , wherein the hole on the flat portion communicates with the electronic component.
7. The waterproof type switch according to claim 1 , wherein the flat portion includes a convex portion formed under a lower surface of the flat portion.
8. An electronic device comprising:
a housing; and
a waterproof type switch disposed in an opening portion of the housing, the waterproof type switch separating an inside and an outside of the housing,
wherein the waterproof type switch includes a waterproof sheet including a flat portion and a side wall portion disposed around the flat portion, an upper portion of the side wall portion coupled to an edge portion of the flat portion;
a switch disposed below the flat portion; and
an electronic component coupled to an upper surface of the flat portion, the electric component being used as a key top,
wherein the waterproof sheet includes a rubber and a reinforcing plate including a first reinforcing plate disposed on the upper surface of the flat portion and coupled to the electric component,
wherein a hole is formed so as to pass through the flat portion and the reinforcing plate.
9. The electric device according to claim 8 , wherein the water proof sheet is formed by integrating the rubber and the reinforcing plate.
10. The electronic device according to claim 8 , wherein the waterproof sheet includes a flange portion extending outward from a lower end of the side wall portion, and a second reinforcing plate is disposed on an upper surface the flange portion.
11. The electronic device according to claim 8 , wherein the waterproof sheet is attached through a water stop member so as to be attachable to and detachable from the housing.
12. The electronic device according to claim 8 , wherein the electronic component includes a biometric authentication module.
13. The electronic device according to claim 8 , wherein a peak position of a displacement-load characteristic of the waterproof sheet and a peak position of a displacement-load characteristic of the switch coincide with each other.
14. The electronic device according to claim 8 , wherein when a height of the side wall portion is L, the switch is disposed so that a peak of a displacement-load characteristic is located at a position of from (½)L to (⅔)L.
