Abstract

The utility model relates to a key type wane switch. The key type wane switch comprises a casing, button components, a support, and a driving piece, wherein the two button components are respectively inserted on the left and the right sides of the support; the driving piece obliquely arranged in a cavity formed between the casing and the support; a slide sleeve component is embedded in a central groove of the driving piece, and a spring is located between the slide sleeve component and the inner end of the central groove; the external end of the slide sleeve component is tightly pressed on a springboard; a dynamic contact component is mounted in an external end hole of the springboard; and a static contact component is arranged below the dynamic contact component and connected with a lateral terminal. The utility model has the benefits that by adopting a vertical structure operation manner to connect and disconnect an operation conversion, dust can be prevented from entering the product; if the key type wane switch is applied outdoors or applied to a juice extractor, rain water and fruit juice can be prevented from entering the inner cavity, so that rain water and solid foreign matters are effectively blocked.

Description

A kind of piano type rocker switch

Technical field

The utility model relates to a kind of appliance switch, relates in particular to a kind of punch press, instrument and equipment, household electrical appliance of being applicable to, is used in particular for the piano type rocker switch of water dispenser, water purifier control.

Background technology

At present, in all kinds of punch presses, instrument and equipment, household electrical appliance and everyday devices, the indispensable needs of its structure possess various switch keys such as switch, control, conversion, and the key button stability of structure is directly connected to the reliability service and permanent application of equipment.As shown in Figure 2, the rocker switch of existing similar structures is generally by shell body 1, button assembly 1, terminal 1 and fixed contact assembly 1, springboard 1 and moving contact assembly 1, spring 1 and slide bushing assembly one 28 combinations; But this class formation is comparatively outmoded, is provided with at each assembly to lack reasonability, and simultaneously, it is inner that water and other impurity are very easy to get into switch, thereby cause product loose contact or electric leakage easily.Therefore, to above problem, need reasonably improve prior art.

The utility model content

To above defective, the utility model provides a kind of piano type rocker switch, is improved to the piano type structure of vertical pressing through the traditional operation mode that will have rocker switch button conversion now, has avoided water and other impurity to be prone to get into the inner defective of switch simultaneously.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of piano type rocker switch; Comprise shell body, button assembly, support, actuator; Said shell body top mounting bracket; This support left and right sides is inserted a button assembly respectively, the actuator that installation one is obliquely installed in the chamber between shell body and support, and said actuator central recess is embedded in slide bushing assembly and between this assembly and groove inner end, is provided with spring; Simultaneously, this slide bushing assembly outer end is pressed on the springboard, in the outer stomidium of said springboard a moving contact assembly is installed.Two height differences that button assembly raises up, one fixed contact assembly is set in said moving contact component placement below and this fixed contact assembly is connected with position, limit terminal.

The beneficial effect of the described piano type rocker switch of the utility model is: the operation conversion of adopting the mode of vertical stratification operation to switch on and off has novel structure, easy to operate, advantage such as cost is lower; Through the support entire upper surface except exceed the surface and two holes of the assembling that matches with button, all the other are all monolithic construction, it is inner to prevent effectively that dust from getting into product; If be applied in outdoor or juice extractor on can prevent that then rainwater or fruit juice from flowing into inner chamber, thereby reach the effect that waterproof is drenched and anti-solid foreign materials gets into preferably.

Embodiment

Shown in Fig. 1-4; The described piano type rocker switch of the utility model embodiment; Comprise shell body 1, button assembly 2, support 3, actuator 4; The support 3 be used to carry button assembly 2 is installed in said shell body 1 top, and it is inequality that these support 3 left and right sides are inserted the height that a button assembly 2 and this two buttons raise up respectively; The actuator 4 that installation one is obliquely installed in the chamber between shell body 1 and support 3; Said actuator 4 central recess are embedded in slide bushing assembly 11 and between this assembly and groove inner end, are provided with spring 10; Simultaneously; These slide bushing assembly 11 outer ends are pressed on the springboard 8; One moving contact assembly 9 is installed in the said springboard 8 outer stomidiums, is positioned at that below, moving contact assembly 9 corresponding positions is provided with a fixed contact assembly 7 and this fixed contact assembly 7 is connected with position, limit terminal 6, said shell body 1 bottom centre position place installation interposition terminal 5.During work; When pressing the button on the right; Button push actuator 4; It is high right low to make its state convert a left side to by the low right height in a left side, and actuator 4 drives the springboard 8 that is stuck on the interposition terminal 5 and the sub-assembly of moving contact assembly 9 through being enclosed within inner spring 10 and slide bushing assembly 11 in this process, and its state is changed; Moving contact assembly 9 converts off-state into by on-states original and position, limit terminal 6 and fixed contact assembly 7 sub-assemblies, and button assembly 2 is stuck in the button bit hole of shell body 1 after making up with support 3.The utility model promptly generally has big superiority by shell body 1, button assembly 1, terminal 1 and fixed contact assembly 1, springboard 1 and moving contact assembly 1, spring 1 and slide bushing assembly one 28 combinations than the rocker switch of existing like product.

Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection range of the utility model.
