Abstract
The utility model relates to a water-proof micro switch which comprises a base and an upper cover, wherein a circuit electrode is embedded in the base, a reed is placed in the base, a water-proof pad is arranged above the reed and concave inwards, the middle at the bottom surface of the water-proof pad is provided with a small circular groove, a button is arranged in the water-proof pad, the middle of the upper cover is provided with a circular hole, and the diameter of the circular hole is identical to that of the upper part of the button; four corners above the base are respectively provided with a locating column, four corners of the upper cover are respectively provided with a locating hole, and the base is fixedly connected with the upper cover by the matching of the locating column and the locating hole; and the upper surface of the upper cover is provided with a driving handle slot close to the circular hole, and a driving handle is placed in the driving handle slot of the upper cover. The water-proof micro switch has the benefits of having functions of watertightness, moisture protection and harmful gas corrosion protection by the sealing of the water-proof pad, thus avoiding the short circuit or invalidation of the switch due to moisture, splashing and damage of harmful gas, greatly prolonging the service life of the switch, and saving maintenance cost for users.
Description
Technical field
The utility model relates to a kind of household electrical appliance assembly, relates in particular to a kind of waterproof micro switch.
Background technology
Along with improving constantly of people's life, various electrical equipment have entered places such as kitchen, parlor and toilet one after another in a large number, make people's life easier and quick like this.Can be for electrical equipment, so environment for use is very harsh to the requirement of appliance switch.Regular tap is easy to occur situations such as " electric leakage ", " short circuit ", " inefficacy " and takes place owing to there is not water-proof function under the environment of humidity, be with inconvenience for people's life, also may endanger people's life or health simultaneously.For this reason, provide a kind of appliance switch with water-proof function particularly important.
The utility model content
The purpose of this utility model provides a kind of waterproof micro switch, and having solved regular tap can not waterproof, protection against the tide and etch-proof problem.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of waterproof micro switch, comprise pedestal and loam cake, described base interior is inlaid with circuit electrode and is placed with reed, the reed top is provided with collision mat, and collision mat indent and middle part, bottom surface have circular sulculus, and button places in the collision mat, the button bottom cooperates with circular sulculus, the loam cake middle part has circular hole, and Circularhole diameter is identical with the button upper diameter, and button top places in the loam cake circular hole and exposes to cap surface; The pedestal top respectively is provided with reference column for four jiaos, and loam cake respectively is provided with location hole for four jiaos, and pedestal cooperates to fix with location hole by reference column with loam cake and is connected; Be provided with the driving handle slot near the circular hole place above the loam cake, driving handle is placed in the driving handle slot.
The beneficial effects of the utility model are: by the sealing of collision mat, make sensitive switch possess waterproof, protection against the tide and etch-proof function, thereby avoided because of moist, dabble and the infringement of pernicious gas causes the short circuit or the inefficacy of switch, greatly prolong the useful life of switch, saved user's maintenance cost.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the front exploded view of the described waterproof micro switch of the utility model embodiment; Fig. 2 is the three-dimensional broken away view of the described waterproof micro switch of the utility model embodiment; Fig. 3 is the assembled formation figure of the described waterproof micro switch of the utility model embodiment.
Among the figure: 1, pedestal; 2, reed; 3, button; 4, collision mat; 5, loam cake; 6, driving handle; 7, reference column; 8, location hole; 9, driving handle slot; 10, circular hole; 11, circular sulculus; 12, circuit electrode.
Embodiment
As Figure 1-3, the described a kind of waterproof micro switch of the utility model embodiment, comprise pedestal 1 and loam cake 5, described pedestal 1 inside is inlaid with circuit electrode 12 and is placed with reed 2, reed 2 tops are provided with collision mat 4, collision mat 4 indents and middle part, bottom surface have circular sulculus 11, button 3 places in the collision mat 4, button 3 bottoms cooperate with circular sulculus 11, loam cake 5 middle parts have circular hole 10, circular hole 10 diameters are identical with button 3 upper diameter, and button 3 tops place in the loam cake circular hole 10 and expose to loam cake 5 surfaces; Pedestal 1 top respectively is provided with reference column 7 for four jiaos, and loam cake respectively is provided with location hole 8 for 5 four jiaos, and pedestal 1 cooperates to fix with location hole 8 by reference column 7 with loam cake 5 and is connected; Be provided with driving handle slot 9 near circular hole 10 places above the loam cake 5, driving handle 6 is placed in the driving handle slot 9.
Contact between collision mat 4 and the base 1 closely, the circuit electrode 12 and the reed 2 of base 1 inside are isolated fully with the external world, prevented liquid, moisture and entering of pernicious gas completely and, prolonged the useful life of switch greatly the erosion of switch circuit electrode 12 and reed 2.
