Systems, methods and non-transitory computer-readable mediums are provided for determining data center resource requirements, such as cooling and power requirements, and for monitoring performance of data center resource systems, such as cooling and power systems, in data centers. At least one aspect provides a system and method that enables a data center operator to determine available data center resources, such as power and cooling, at specific areas and enclosures in a data center to assist in locating new equipment in the data center.

A mouse device includes a casing, a circuit board and two button modules. The circuit board is disposed within the casing. Each button module includes an electronic switch, a button lid, a first protrusion post, a second protrusion post and a buffering structure. The electronic switch is disposed within the casing. An end of the button lid is connected with the casing. The first protrusion post and the second protrusion post are disposed on the bottom surface of the button lid. The buffering structure is disposed on the casing and aligned with the second protrusion post. The second protrusion post is inserted into a buffering hole of the buffering structure. While the button lid is depressed or the pressing force is released, the buffering structure is contacted or not contacted with the second protrusion post along a first lateral direction and/or a second lateral direction.

A touch module includes a touchpad assembly and a connection assembly. The connection assembly includes a main body, plural first coupling plates and plural protrusion posts. When the connection assembly is accommodated within a computer casing, the plural first coupling plates are penetrated through plural first openings of the computer casing and the plural protrusion posts are inserted into the corresponding fixing structures. The plural protrusion posts and the corresponding fixing structures are collaboratively formed as a hinge structure. While the touchpad assembly is pressed down, the connection assembly is swung relative to the computer casing by using the plural protrusion posts as the pivotal shafts, so that the touchpad assembly is correspondingly swung. Due to the hinge structure, the touchpad assembly is swung along a fixed direction. Consequently, the touch module is operated stably.

A switch device includes an operating knob on which a tilting operation is performed, a detected portion that tilts with the tilting operation of the operating knob, a detection portion that detects movement of the detected portion, and a substrate on which the detection portion is arranged. The detection portion is aligned in an in-plane direction of the substrate and performs a switching operation upon detection of movement of the detected portion in the in-plane direction.
