A mouse device includes an upper cover, an intermediate cover, a lower cover, a circuit board, and two switches. Two protrusion posts of the upper cover are respectively penetrated through two perforations of the intermediate cover. Two first pivotal parts of the upper cover are respectively connected with two second pivotal parts of the intermediate cover. The upper cover is fixedly connected to an annular sidewall of the lower cover. The circuit board and the two switches are disposed on the lower cover. When the upper cover is rotated relative to the intermediate cover through the two first pivotal parts and two second pivotal parts, one of the two switches is triggered by the corresponding protrusion post so as to generate a corresponding electronic signal. The use of the present mouse device can prevent from introducing foreign matters, reduce the depressing force and avoid erroneously triggering the switch. |

1. A mouse device, comprising:
an upper cover comprising two protrusion posts and two first pivotal parts, wherein the two protrusion posts and the two first pivotal parts are disposed on an inner surface of the upper cover; an intermediate cover disposed under the upper cover, and comprising two perforations and two second pivotal parts, wherein the two protrusion posts are respectively penetrated through the two perforations, wherein the two second pivotal parts are respectively connected with the two first pivotal parts, so that the upper cover is rotatable relative to the intermediate cover; a lower cover disposed under the intermediate cover, and connected with the intermediate cover; a circuit board disposed over the lower cover, and arranged between the intermediate cover and the lower cover; and two switches disposed on the circuit board, wherein when the upper cover is rotated relative to the intermediate cover in a first direction or a second direction, the corresponding switch is triggered by the corresponding protrusion post so as to generate a corresponding electronic signal. |
