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 [0001] The invention relates to the technology in the field of micro switches, in particular to a micro switch capable of switching between audible and silent. Background technique [0002] The micro switch is a quick changeover switch actuated by pressure. Because the distance between the contacts of the switch is relatively small, it is called a micro switch, also known as a sensitive switch. Micro switches are widely used, such as computer mouse, car mouse, automotive electronic products, communication equipment, military products, test instruments, gas water heaters, gas stoves, small appliances, microwave ovens, rice cookers, floating ball equipment, medical equipment, Building automation, power tools and general electrical and radio equipment, 24-hour timers, etc. [0003] Micro switches are divided into audible micro switches and silent micro switches according to the classification of sound and silence. It is the sound that makes it noisy on certain...
