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, conducting portion and cover plate, described conducting portion comprises static contact and pin, described pin runs through base setting and has 2 at least, described static contact is arranged on the centre position that the inner and described static contact of base is fixed on pin, described switch element comprises reed, handle and water-proof elastic layer, described water-proof elastic layer is arranged between reed and handle, the two ends that described reed is set to arch and described reed are connected with pin, described cover plate is provided with the installing hole supporting with switch element and securing member, described handle is 0.4 times to 0.7 times that water-proof elastic aspect is amassed towards water-proof elastic layer one end area.
By adopting technique scheme, described handle is stressed to be pressed down the reed that water-proof elastic layer drives described water-proof elastic layer to press down described arch and makes described reed middle part touch static contact, described pin, static contact forms and is electrically connected to reed, thereby realize the effect of folding circuit, the pressure that described handle causes described water-proof elastic layer to be subject to towards the too small meeting of an end area of water-proof elastic layer is too concentrated, described water-proof elastic layer is easily crushed by handle, described handle causes the described reed area that is stressed excessive and affect life-span of reed towards the excessive meeting of an end area of water-proof elastic layer, therefore described handle is set to 0.4 times to 0.7 times of water-proof elastic layer towards an end area of water-proof elastic layer, make handle decentralized to the pressure of water-proof elastic layer, reduced the suffered pressure of described water-proof elastic layer, thereby avoid described water-proof elastic layer to break in frequent pressurized process and cause the waterproof of described touch-switch, anti-dust performance lost efficacy.
The utility model is further set to: described handle is provided with chamfering towards its edge, one end of water-proof elastic layer.
By adopting technique scheme; when described handle contacts with water-proof elastic layer; its engagement edge arranges the stressed cushioning effect that plays that chamfering can be to water-proof elastic layer; further the described water-proof elastic layer of protection can stressedly too much not cause its breakage in high-frequency use procedure, extends the useful life of described touch-switch.
The utility model is further set to: described static contact is provided with annular projection structure towards the one side of reed.
By adopting technique scheme, when described reed is pressed down, to first touch described annular projection structure and form electrical connection, while avoiding described reed to press down, by base, in injection moulding process, may be occurred burr pad to live and cause the loose contact of described touch-switch internal electrical, in addition when described touch-switch surprisingly enters dust, dust can be forced into the bottom of annular projection structure when reed presses down, prevent dust pad between reed and static contact and cause its loose contact, making described touch-switch more reliable and more stable.
The utility model is further set to: described installing hole is set to counterbore, and described securing member is located in installing hole, and described securing member is installed rear its head lower than the outer surface of described cover plate.
By adopting technique scheme, described securing member just can not expose outside cover plate, protects carrying that described securing member can be in the touch-switch course of processing, collision and damages.
The utility model is further set to: described securing member is set to rivet, and described rivet and base are integral type setting.
By adopting technique scheme, described rivet and base are integral type setting reduces the manufacturing procedure of described touch-switch, avoids described touch-switch to be broken in unnecessary processing handling process.
