A mouse device includes a lower casing, a circuit board, an upper casing, a button and an elastic element. The switch module is disposed on the circuit board. The circuit board is located over the lower casing. The upper casing has a slot. The upper casing and the lower casing are combined together. The button includes a push structure. The push structure includes a contacting portion corresponding to the switch module. The push structure is penetrated through the slot. The button is pivotally coupled to the upper casing. Consequently, the button is permitted to be swung relative to the upper casing. The elastic element is arranged between the contacting portion and the upper casing. Moreover, two ends of the elastic element are respectively contacted with the contacting portion and the upper casing. Consequently, the contacting portion is in contact with the switch element.

A replaceable key structure includes a key holder and a circuit board. The key holder is disposed above a circuit board. The key holder is formed with a mounting slot for selectively receiving a first key module or a second key module therein. A magnetic sensor and a contact connector are disposed on the circuit board positionally corresponding to the mounting slot of the key holder. The first key module has a shaft, and a magnetic element disposed on the bottom of the shaft. The magnetic sensor can output an analog signal when the magnetic element approaches. The second key module has a trigger switch which has two electrical terminals disposed on the bottom surface of the second key module. When the second key module is installed in the mounting slot, the electrical terminals can be electrically connected to the contact connector.

A terminal stand is provided. The terminal stand includes a base body, a movable part, a metal elastic part, a first signal element and a second signal element. One end of the metal elastic member includes two first abutments. The first signal element is disposed in a second receiving slot. One end of the first signal element includes a first contact portion and a second abutment. The second signal element is disposed in the second receiving slot. One end of the second signal element includes a second contact portion. The second contact portion contacts with the first contact portion and makes a signal circuit. When the movable member is pressed, the movable member drives the two first abutments to move, and the abutment drives the second abutment to move, with the first contact portion leaving the second contact portion, and the signal circuit is in an off-state state.

A device having a memory configured to store information indicating debounce times for the device's switches and having circuits configured to determine whether the switches are depressed and closed based on the debounce times. The debounce times are updated based on the age of the device and/or switch usage. The method for debouncing may be performed by a computer having computer-readable media directed to adjusting the debounce times based on the age of the device containing the switches.

A seat occupancy sensor includes: a first sensor group having a plurality of first sensor cells that are arrayed in a front-rear direction of a seat and become conductive as a load is applied thereto; a second sensor group having a plurality of second sensor cells that are arrayed in the front-rear direction, farther on a front side of the seat and closer to an end of the seat in a width direction than the first sensor group, and that become conductive as a load is applied thereto; and an electronic control unit. The electronic control unit determines that someone is sitting on the seat when both of at least one of the first sensor cells and at least one of the second sensor cells become conductive.

A keyboard device includes a base plate and a key structure. The key structure includes a keycap, a first connecting element, a second connecting element and a stabilizer bar. The first connecting element and the second connecting element are arranged between the base plate and the keycap and connected with the base plate and the keycap. The stabilizer bar is fixed on the first connecting element and the second connecting element. Since the stabilizer bar does not collide with the base plate to generate the unpleasant noise, the keyboard device of the present invention is capable of reducing the noise. Moreover, since the stabilizer bar is fixed on the first connecting element and the second connecting element, it is not necessary to install hooks corresponding to the stabilizer bar on the keycap and the base plate and the fabricating cost is reduced.
