821st, the second flat guided way 822, first raise guided way 823 or the second and raise roller 854 on guided way 824；When first not
When the roller 854 of dynamic contact 85 is supported by the first flat guided way 821, the roller 854 of the second motionless contact 86 is flat by second
Guided way 822 supports, and now motionless the motionless of contact 86 of not moving contacting plate 852 or the second of the first motionless contact 85 connects
Contact 852 is close to moved end contact 84.
It is close in order that obtaining moved end contact 84 with the first motionless motionless contact 86 of contact 85 or the second, moved end contact
Part 84 includes：Moved end contact chip 841 above rotating disc 82, moved end contact chip 841 are used for tight with not moving contacting plate 852
Patch, moved end contact chip 841 are fixed with the mobile bar 842 through rotating disc 82, and mobile bar 842 is located on vertical direction, mobile bar
842 through there is contact spring 843, and the one end of contact spring 843 is fixed with moved end contact chip 841, and the other end of contact spring 843 is with turning
Moving plate 82 is fixed, and when moving contacting plate 852 is not close to moved end contact chip 841, contact spring 843 is compressed, moved end contact chip
841 and mobile bar 842 be made of conductive material, mobile bar 842 is used to form the moved end of controllable single-pole double-throw switch (SPDT).By
In when roller 854 raises guided way 824 from second and jumps to the first flat guided way 821, the flat guided way 821 of roller 854 to the first
Between have distance, same not moving contacting plate 852 also has distance between moved end contact chip 841, is returned even in contact spring 843
Again to moving contacting plate 852 does not drop on moved end contact chip 841 from higher position yet during original position, in the whole first motionless contact
Under the Action of Gravity Field of the motionless contact 86 of part 85 or the second, the first flat pair roller 854 of guided way 821 supports, while motionless contact
Piece 852 is close to moved end contact chip 841, and contact spring 843 is compressed.
In order to which the moved end contact 84 realized in rotation process can form the moved end of fixed controllable single-pole double-throw switch (SPDT),
Annulus is fixed with the bottom surface of rotating disc 82, rotating disc 82, which is adopted, to be made from an insulative material, and the rotary shaft of switch motor 83 passes through annulus
Center and contactless with annulus, annulus is connected with mobile bar 842 by wire, be fixed with switching chamber 811 bottom surface around with
Ring-type pedestal outside annulus, through there is a contact bar in horizontal direction on pedestal, contact bar be located at end in pedestal and
Annulus outer wall is close to and is dome-type structure, and the end that contact bar is located at outside pedestal, which passes through, a holddown spring, holddown spring one
End is fixed with pedestal, and the holddown spring other end is fixed with contacting bar, and annulus and contact bar are made of conductive material, are contacted
Bar is used for the moved end for forming controllable single-pole double-throw switch (SPDT), and holddown spring is in confined state.Due in rotation process, moved end
Not necessarily, therefore the moved end for forming fixed controllable single-pole double-throw switch (SPDT) is very troublesome for the position of contact 84, so circle is set
Ring, contact bar and pedestal so that the electricity of the band of moved end contact 84 in connection rotation is transformed into transversely movable contact bar
On, contact bar only sets a wire, and section long enough of the wire in switching chamber 811 just, can just form the controllable list of fixation
The moved end of double-pole double throw switch.Holddown spring enables contact bar to be moved under the rotation of annulus, also can guarantee that contact bar and circle
Ring is close to, and the end be close to annulus of contact bar be ball shape structure, can ensure annulus is relative contact bar rotation when annulus and
It is smaller to contact the frictional force of bar, avoids contact with bar well damage.
Due to, it is necessary to new first relay or the second relay are connected with high voltage power supply, therefore easily going out when changing

The screwed hole of connection is located between lid 12 and triggering chamber 14, and shell body 11 is recessed close to the face of lid 12 and compresses hole 16,
The diameter for compressing hole 16 is more than the diameter of screwed hole, and the perforation being aligned with compressing hole 16 is offered on lid 12；Each stop group
Part 5 includes：Stopper 51, stopper 51 are the circular arc bent to screw rod 46, and stopper 51 connects oriented screw rod 46 and extended
Moving cylinder 52, moving cylinder 52 is slidingly arranged on a guide rod 53, and end of the guide rod 53 away from stopper 51 is fixed on
On the round end of screw rod 46, the top surface position of screw rod 46 is higher than the top surface position of stopper 51, and moving cylinder 52 is fixed with one
Press block 54, press block 54 are median surface and median surface and the centerline parallel of screw rod 46 and be press block close to the face of screw rod 46
54 faces away from screw rod 46 are contact surface, press block 54 be it is trapezoidal, the big end of press block 54 close to stopper 51, press block 54
Small end positioned at compressing in hole 16, and the distance of contact surface to the center line of screw rod 46 held greatly of press block 54 be more than compress hole 16 partly
Footpath, the distance of contact surface to the center line of screw rod 46 of the small end of press block 54 are less than the radius for compressing hole 16, and guide rod 53, which passes through, to be had
One compresses spring 55, and the one end and screw rod 46 for compressing spring 55 are fixed, and the other end and moving cylinder 52 for compressing spring 55 are fixed；When
When the big end of trigger head 47 contacts with pulley 45, face of the stopper 51 away from screw rod 46 is more than to the vertical range of perforated base line
The radius of perforation；When the small end of trigger head 47 contacts with pulley 45, face of the stopper 51 away from screw rod 46 to perforated base line
Vertical range be less than perforation radius.Due to when the big end of trigger head 47 contacts with pulley 45 stopper 51 away from screw rod 46
Face to perforated base line vertical range be more than perforation radius, it is therefore desirable to lid 12 is separated with shell body 11, just must
Must rotary screw 46 so that the small end of trigger head 47 contacts with pulley 45, while face of the stopper 51 away from screw rod 46 is to perforating
The vertical range of center line is less than the radius of perforation, so, prevents from maloperation so that only in the wiring of switching circuit board 2
Lid 12 can be opened after post power-off.And this connected mode, disposable power-off and the release of lid 12 are realized, facilitates behaviour
Make so that operation is easier.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
