Touch-switch, is again key switch, when use, connects to switching manipulation pressuring direction switching function is closed with the condition that meets operating physical force, and in the time cancelling pressure, switch disconnects, and by metal clips, stressed variation realizes break-make to its internal structure.
Touch-switch is of many uses, and the operational environment of facing is also had nothing in common with each other, but its volume is little, and electricity gets an electric shock and affected by the fouls such as dust and cause malfunctioningly, so designed again waterproof light-touch switch, can stop that moisture, dust enter switch inside.
At present, waterproof light-touch switch (Chinese patent that application number is 201020651583.1 discloses a kind of water proof switch) on market, it comprises binding post, base, reed, cover plate and handle, between being characterized under base and cover plate, add water-proof silica-gel layer, this type of switch assembling is loaded down with trivial details, need between reed and water proof rubber, drop by pad pasting to prevent reed, and rubber is installed and also needed location, be limited to process technology restriction, waterproof effect is restriction to some extent also.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide the touch-switch that a kind of production process is simple, waterproof effect is outstanding.
For achieving the above object, the utility model provides following technical scheme: a kind of waterproof light-touch switch, comprise base, be arranged on the switch element on base and switch element is fixed to the cover plate on base, described base is provided with the conducting portion with external circuits conducting, described switch element comprise reed, handle and cover reed and handle between water-proof elastic layer, between described cover plate and base, be provided with fastening part, the end face that described cover plate and water-proof elastic layer are conflicted is provided with the pre-splenium of projection.
By adopting technique scheme, described cover plate is by pre-splenium and water-proof elastic layer interference precompressed, water-proof elastic layer preloading defeated reed makes reed can not slide and come off, reduce the film process in original production operation, promote touch-switch production efficiency, and the pre-splenium of projection is pressed into, water-proof elastic layer makes to conflict more closely between cover plate and water-proof elastic layer, contact-making surface is larger, improves the waterproof and dustproof performance of touch-switch.
This use is novel to be further set to: described pre-splenium arranges along cover plate end face for one week continuously, and the inside and outside limit of pre-splenium of described projection is provided with rounding.
By adopting technique scheme, described pre-splenium arranges along cover plate end face for one week continuously, precompressed water-proof elastic part to greatest extent, and the inside and outside limit of described pre-splenium arranges rounding, while making cover plate precompressed water-proof elastic part, can not crushed by pre-splenium edge, ensure touch-switch water resistance.
The utility model is further set to: described reed is with conducting portion activity conflict shape the one side being electrically connected and is provided with annular projection structure.
By adopting technique scheme, the stressed elastic waterproof layer that presses down of described handle, while flattening reed by elastic waterproof layer, the conducting portion of can more easily conflicting forms electrical connection, avoid reed to be pressed down the loose contact that may cause by large area, and in the time surprisingly entering dust in the course of processing, dust can be pressed down the depressed part falling in the middle of conducting portion by reed, remove the switch failure that dust may cause, make touch-switch more reliable and more stable.
The utility model is further set to: described base and cover plate snapping, and described fastening part is provided with several, and described fastening part comprises the catching groove on buckle, the cover plate on base, described buckle and catching groove size adaptation.
By adopting technique scheme, described base and cover plate be by suitable buckle, draw-in groove snapping, and when pre-splenium compression water-proof elastic part on described cover plate, water-proof elastic part provider is to restoring force, thereby it is tightr that buckle is connected with draw-in groove.
