Abstract

The utility model relates to an improved pushing switch structure, which mainly adopts an elastic element having a moving part made of a bended metal material and moves inside a main body, and the two free ends of the moving part respectively has an supporting part by being extended, the supporting part is arranged inside the main body of the pushing switch. When the elastic element is pressed, the inner diameter of the moving part is slightly retracted, to lead the supporting part to generating an action of being pressed downward, so as to contact and break over with the two connectors of the pushing switch, to form an electrical character output, when a pressing element is not forced by external force, the elasticity of the elastic element can return the pressing element to an original position.

Description

Modified model push switch structure

Technical field

The utility model system relates to a kind of modified model push switch structure, relates in particular to a kind of simplification parts, and assembling saves time more, saving of labor and cost-effective push switch.

Background technology

The utility model applicant formerly and through checking and approving " modified model push switch structure " (push switch improved structure) utility application of No. 2457716 of bulletin, the push switch structure of being mentioned in this application that can be used as signal conduction or output signal includes: a body, one is configured in the two-terminal on the described body, one is configured in first flexible member of described body interior action, one is configured in described body interior and is positioned at the press element of first flexible member top, an and closure elements that is enclosed on the described body, when described press element is subjected to external force pressure, be pressed on first flexible member and drive the action of second flexible member, this moment, first flexible member promptly contacted conducting with two-terminal after being pressed down, form electrical characteristic output, when press element was not subjected to external force pressure, this was first years old, the elastic force of two flexible members itself can make press element be back to original position.

Though above-mentioned " modified model push switch structure " (push switch improved structure) utility application, has simple structure than general traditional push switch structure, and less contact point, and then reduce impedance significantly, cause signal can not be attenuated by push switch.But, this " modified model push switch structure " (push switch improved structure) utility application need use two flexible members, cost of manufacture is increased, and when assembling the time is also taken a lot of work and operation, in addition, because two-terminal is positioned at the motion space, press down area and have in limited time when second flexible member is stressed, often causing actual conducting two-terminal area is not contact fully, and causes the situation that signal output is interrupted to take place, and influences its virtual utility.

Summary of the invention

14a, 14b, is formed with an opening 15 that communicates with motion space 11 between this two retainings edge 14a, the 14b; Again described abundant 12a, 12b both sides and below respectively be provided with a

symmetrical location division

17a, 17b, 17c;

Respectively have

tabs

21a, 21b on this two-terminal 2a, the 2b, be extended with a contact site 22b who enters 11 li of motion spaces in the side of tabs 21b in addition, the contact site 22a of another tabs 21a then is connected in arbitrary junction surface 13a, and this two-

terminal

2a, 2b adopt pre-buried mode and body 1 integral injection molding;

This flexible member 3, be bent into by a metal material and had an

operating member

31,31 liang of free ends of this operating member respectively are extended with a

support portion

32a, 32b, this

support portion

32a, 32b are configured among above-mentioned junction surface 13a, the 13b, when flexible member 3 pressurizeds, these operating member 31 internal diameters produce minimal shrink, and causing

support portion

32a, 32b to produce an action that is pressed down can contact with above-mentioned

contact site

22a, 22b;

This press element 4, has a press section 41 on it, this press section 41 undertakes a neck 42 that is positioned at opening 15 places, undertake a compression part 43 on this neck 42, this compression part 43 is provided with the disposal area 44 of the above-mentioned operating member 31 of a connection, and

corresponding support portion

32a, 32b place are provided with a depressed area 46 below compression part 43; In addition, on described neck 42 or compression part 43, be provided with one and after pushing, produce the hole 45 that press element 4 has the sensation of being pressed down;
