Pin forms access altogether.When motion bar 8 is when external force moves down, movable component is by compressive deformation, in activity bar assembly
Rotating block 9 contact and start turning with the upper lobes of bottom case boss 102；The meeting when movable component is perpendicular to movable contact spring component
There is dynamic balance, main elastic slice 11 no longer generates downward pressure effect to movable contact spring component, and the main elastic slice 11 of movable component is in most
Big decrement, main 11 elastic force of elastic slice is maximum, at this time movable block 13 auxiliary elastic slice 12 act on lower camber side and locating piece grooving 161 and
Bottom case grooving 111 contacts, because movable block 13 and two grooving inclined-planes are still not at plumbness, thus generate pushing power act on it is dynamic
On contact assemblies, and then occur small between sound contact when avoiding main elastic slice 11 is vertical with movable contact spring component from dynamic balance occur
Gap leads to switch circuit breaking or scintillation.When motion bar 8 continues the slight distance that moves down again, main elastic slice 11 has crossed dynamic balance point
Moment forms angle between position, with movable contact spring component and movable component, at this time at 13 cambered surface of movable block and two grooving face inclined-planes
In plumbness, downward pressure is no longer generated to movable contact spring component, it is main because main 11 elastic force of elastic slice is much larger than auxiliary 12 elastic force of elastic slice

When closely perpendicular to movable contact spring component, the lower lobes that rotating block 8 contacts bottom case boss 102 are started turning, when movable component is vertical
It will appear dynamic balance when movable contact spring component, main elastic slice 11 no longer generates upward pressure effect, movable component to movable contact spring component
Main elastic slice 11 be in maximum compressibility, main 11 elastic force of elastic slice is maximum, at this time movable block auxiliary elastic slice 12 act on lower camber side with
Locating piece grooving 161 and bottom case grooving 111 contact, because movable block 13 and two grooving inclined-planes are still not at plumbness, to produce
Pressure acts on movable contact spring component in life, and then avoids main elastic slice is vertical with movable contact spring component from sound contact when dynamic balance occur
Between there is minim gap and lead to switch circuit breaking or scintillation.When the continuation of motion bar 8 again up cross by slight distance, main elastic slice
Dynamic balance point position, moment forms angle between movable contact spring component and movable component, at this time movable block cambered surface and two grooving faces
Inclined-plane is in plumbness, no longer generates upward pressure to movable contact spring component, because main 11 elastic force of elastic slice is much larger than auxiliary elastic slice 12
Elastic force, the release of main 11 elastic force of elastic slice promotes movable contact spring component by downward active force and moment is slided down, the second contact 7 with
Normally opened plug-in pin 18 disconnects, and normally opened 18 open circuit of plug-in pin, the first contact 6 is contacted with normally closed plug-in pin 17, and normally closed plug-in pin 17 is logical
Road.Motion bar continuation up moves, and motion bar boss 81 contacts 15 with the second separation member and contacts and the second separation member 15 is pushed to enclose
It is rotated around cylinder, when movable contact spring component occurs once in a while that under motion conditions down, the second separation member 15 can not stir movable contact spring group
Part makes its slide downward, thus disconnect the second contact 7 with normally opened plug-in pin 18, normally opened 18 open circuit of plug-in pin, the first contact 6
It is contacted with normally closed plug-in pin 17, normally closed 17 access of plug-in pin.
Another kind avoids switch from occurring powering off in critical localisation or scintillation mode is in principles above, is lived using adjustment
The upper lobes contact position of rotating block 9 and bottom case boss 102 on lever component, makes rotating block 9 and movable component dynamic balance
The dynamic balance position formed between position elder generation and movable component and movable contact spring component, so that avoiding switching breaks in critical localisation
Electricity or scintillation.
When plug-in pin component only has normally closed plug-in pin 17, according to above-mentioned working principle, under normal conditions, the first contact 6 with
Normally closed plug-in pin 17 is kept in contact, and normally closed plug-in pin 17 keeps access with public pin 3；Motion bar 8 is pushed by external force, the first touching
Point 6 is disconnected with normally closed plug-in pin 17, normally closed plug-in pin 17 and public 3 open circuit of pin；When motion bar 8 is by the bullet of return springs 10
Power effect moves upwards, and the first contact 6 resumes contacts with normally closed plug-in pin 17, normally closed plug-in pin 17 and public 3 access of pin.
When plug-in pin component only has normally opened plug-in pin, according to above-mentioned working principle, under normal conditions, the second contact 7 with often
It opens plug-in pin 18 to remain open, normally opened plug-in pin 18 and public 3 open circuit of pin；Motion bar 8 is pushed by external force, the second contact 7 with
Normally opened plug-in pin 18 contacts, and normally opened plug-in pin 18 and public pin 3 form access；When motion bar 8 is by the bullet of return springs 10
Power effect moves upwards, and the second contact 7 is disconnected with normally opened plug-in pin 18, normally opened plug-in pin 18 and public 3 open circuit of pin.

Only one main elastic slice 11 forms, and remaining component structure remains unchanged, identical in the effect and embodiment one of main elastic slice 11.Implement
In example one, there are two types of solve switch to occur powering off or the mode of scintillation in critical localisation.One is: close to switch triggering
When position, rotating block 9 is contacted with bottom case boss 102, and the movable component compared with movable component of rotating block 9 is arrived first with movable contact spring component
Rotation is generated up to dynamic balance position, rotating block 9 rotates moment free component and movable contact spring component forms angle, to avoid living
Dynamic component and movable contact spring component, which form dynamic balance, leads to that powering off occurs in switch or scintillation occurs.Another kind is: opening close
When closing trigger position, rotating block 9 is contacted with bottom case boss 102, rotating block 9 movable component and movable contact spring group compared with movable component
Part evening reaches dynamic balance position, is connect at this time by 13 arc contact surface of movable block with locating piece grooving 161 and bottom case grooving 111
Touching generates pressure and acts on movable contact spring component, come avoid when main elastic slice 11 generates dynamic balance with movable contact spring component sound contact it
Between there is minim gap and lead to switch circuit breaking or scintillation.Embodiment two is due to using single spring-piece type movable component, so being
Occur powering off or scintillation to solve switch in the first manner.Remaining component effect is similar, repeats no more its course of work
