Abstract

The invention provides a key device capable of reducing pressing noise, and the device comprises a bottom plate, a key cap, a supporting rod, and a circuit board. The bottom plate is provided with a hole seat, and the hole seat is provided with a pivot hole. The key cap is disposed above the bottom plate, and the supporting rod is provided with a first rod part and a second rod part. The first rod part is pivoted to the key cap, and the second rod part passes through the pivot hole. The circuit board is disposed on the bottom plate, and comprises a first structure, a first elastic butting tongue piece, and a second elastic butting tongue piece. The first elastic butting tongue piece extends to the first structure in a direction perpendicular to the second rod part. The second elastic butting tongue piece extends to the first structure in a direction perpendicular to the second rod body, and is opposite to the first elastic butting tongue piece. The device can solve a problem that a key device is liable to generate noise in a pressing process.

Description

technical field [0001] The present invention relates to a button device, in particular to a button device capable of reducing pressing noise. Background technique [0002] Generally speaking, the keyboard layout has a plurality of key devices for the user to press to generate an input signal, so that the user can use the plurality of key devices to input characters, numbers, symbols and the like. The known key device can be provided with a support bar (linkbar), which is used to support the keycap of the key device to move up and down relative to the bottom plate, and the conventional support bar and the bottom plate are usually a shaft (shaft)-hole (hole) fit , and the shaft hole is usually a clearance fit. Therefore, when the key device is pressed, the above-mentioned shaft member and the hole wall of the hole often collide with each other to generate noise. Contents of the invention [0003] Therefore, one of the objectives of the present invention is to provide a but...
