Abstract
The invention discloses a switchable sound/soundless micro-switch, comprising a shell, a movable contact, a fixed contact, an arch resilient sheet, a sliding switching piece, a fixing piece and a key. The shell has a sound position and a soundless position; the sliding switching piece is located below the arch resilient sheet, and can be slidably arranged between the sound position and the soundless position; and a convex part is arranged on the surface of the sliding switching piece. Therefore, when the sliding switching piece is at the soundless position, the convex part is located below the arch resilient sheet, and the arch resilient sheet is used for stopping a working stroke position of pressing the arch resilient sheet downward, so as to prevent the arch resilient sheet from producing sound, and the soundless mode is realized. When the sliding switching piece is located at the sound position, a space is formed between the sliding switching piece and the arch resilient sheet, so that the sound is produced at the working stroke position of pressing the arch resilient sheet downward, and a sound mode is realized. The sound mode and the soundless mode can be freely switched according to user demands, so that the use requirements of a user can be met, and convenience is brought to the utilization of the user.
Description
Technical field
The present invention relates to the sensitive switch art, refer in particular to a kind of changeable sound/noiseless sensitive switch.
Background technology
