Abstract

Provided is a key switch structure wherein a membrane sheet (7) having a movable contact point (7e) and a stationary contact point (7d) is provided between a housing (5), which supports a key top (1) so as to allow the key top to be pushed downward and a base plate (8). The movable contact point (7e) is brought into contact with the stationary contact point (7d) by a downward push to the key top (1), so that a switch is closed. In the key switch structure, the inside of a device's main body is completely shielded from outside air, and water is completely prevented from entering the inside of the device's main body. A plate (6) provided with a plurality of attachment holes (6g) corresponding to fixing pins (5f) of the housing (5) is provided on the membrane sheet (7), so that the fixing pins (5f) are secured in the attachment holes (6g) of the plate (6).

Description

technical field [0001] The present invention relates to a key switch structure in a keyboard device such as a personal computer. Background technique [0002] In recent mobile devices such as notebook personal computers (hereinafter referred to as "device bodies"), long-term portability is possible due to longer battery life, and all-weather devices are required. In order to realize this requirement, techniques for obtaining drip-proof properties and further water-repellent properties are required. For example, even when the keys are operated outdoors in rainy weather, there is a demand for a technology capable of preventing rainwater from entering the main body of the device from the keyboard. [0003] Figure 4 It is a cross-sectional view of a conventional key switch in consideration of this requirement, Figure 5 It is an exploded perspective view of a conventional key switch. [0004] As shown in this figure, the existing key switch structure consists of the followin...
