The technical solution adopted for the present invention to solve the technical problems is：The durable electric power driving switch includes pedestal, institute
State and sealed tube is fixed with pedestal, Feng Youyi sections mercury in the sealed tube；The lower section of the mercury is provided with and can closed
The main sliding plug slided in pipe；The sealed tube is externally provided with the sliding block that can drive the main sliding plug；The main sliding plug is in sealed tube
During interior lower limit position, in the sealed tube, the top of the mercury be equidistantly fixed with electric conductor, wherein, bottom
Electric conductor is electrically connected with the anode connector on the pedestal, and remaining electric conductor concatenates common connection again after a resistance respectively
Positive terminal on to the pedestal；When the main sliding plug slides into upper extreme position, mercury above main sliding plug simultaneously with
Each electric conductor is in contact.
Preferably, the sealed tube is glass tube, the electric conductor is in the annular shape parallel with sealed tube cross section, Gu
It is scheduled on the inside of sealed tube；So that user is it will be clear that the number for the electric conductor that mercury is touched, with
Current gear is determined, without making scale on the pedestal again.
Preferably, the sealed tube completely encloses, inside it in addition to the mercury, vacuum is formed；The main sliding plug
It is made up of ferromagnet, the sliding block is arranged in the chute on the pedestal, main sliding plug described in face, and the sliding block is by strong magnetic
Body is formed, and magnetic attraction is formed with the main sliding plug, and during so that the sliding block sliding up and down, the main sliding plug follows sliding block sealing
Slided up and down in stopped pipe；So as to so that the mercury in sealed tube is isolated from the outside completely, not only improve security, and simplify
The driving structure of the main sliding plug, moreover it is possible to make the design length of sealed tube be unlikely to long.
Preferably, the top of the mercury also covers a upper sliding plug that can be slided in the sealed tube, it is described
Upper sliding plug upwardly extends one section of insulation tube, and the upper end of the insulation tube connects a top sliding plug；The upper sliding plug center offers
With the through hole connected inside the insulation tube；The overall averag density that the upper sliding plug, insulation tube, top sliding plug are formed is less than water
Body；The electric conductor be arranged at around it is described closing inside pipe wall groove in so that the upper sliding plug in sealed tube on glide
When dynamic, not with the conductive body contact；Upper extreme position of the upper sliding plug in the sealed tube is higher than described in the top
Electric conductor.
The beneficial effects of the present invention are：The durable electric power driving switch in use, when the main sliding plug is in
In sealed tube during lower limit position, positive terminal, anode connector on the pedestal mutually disconnect；And when the main sliding plug is gradual
Upward sliding, and when mercury is gradually raised upwards, gradually increase with the electric conductor that the anode connector electrically conducts,
It can be seen from circuit relationships, mercury is per one electric conductor of more contact upwards, then the resistance between positive terminal, anode connector is just
Decline a shelves, when main sliding plug slides into upper extreme position, resistance is minimum between positive terminal, anode connector, circuit power
Reach maximum；Because during gear switch, in the absence of any rigid contact, therefore the switch is difficult to damage, prolonged resistance to
With.

Fig. 2 is the structural representation of this durable electric power driving switch embodiment two.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment one：
In the embodiment one shown in Fig. 1, the durable electric power driving switch includes pedestal 1, and envelope is fixed with the pedestal 1
Stopped pipe 2, Feng Youyi sections mercury 21 in the sealed tube 2；The lower section of the mercury 21 is provided with what can be slided in sealed tube 2
Main sliding plug 3；The sealed tube 2 is externally provided with the sliding block 4 that can drive the main sliding plug 3；The main sliding plug 3 is in sealed tube 2
During lower limit position, the top of interior, the described mercury 21 of the sealed tube 2 is equidistantly fixed with electric conductor 5, wherein, bottom
Electric conductor 5 is electrically connected with the anode connector 61 on the pedestal, and remaining electric conductor concatenates common again after a resistance R respectively
The positive terminal 62 being connected on the pedestal 1；When the main sliding plug 3 slides into upper extreme position, the mercury of the main top of sliding plug 3
Post 21 is in contact with each electric conductor 5 simultaneously.
In the present embodiment one, the sealed tube 2 is completely enclosed, inside it in addition to the mercury 21, forms vacuum；It is described
Main sliding plug 3 is made up of ferromagnet, and the sliding block 4 is arranged in the chute on the pedestal 1, main sliding plug 3 described in face, and described
Sliding block 4 is made up of kicker magnet, and magnetic attraction is formed with the main sliding plug 3, during so that the sliding block 4 sliding up and down, the main cunning
Plug 3 follows sliding block 4 to be slided up and down in sealed tube 3；So as to so that the mercury in sealed tube 3 is isolated from the outside completely, not only
Security is improved, and simplifies the driving structure of the main sliding plug 3, moreover it is possible to the design length of sealed tube 2 is unlikely to long.
Above-mentioned driving switch, the sealed tube 2 are glass tube, and the electric conductor 5 is in parallel with the cross section of sealed tube 2
Annular shape, it is fixed on the inside of sealed tube 2；So that user is it will be clear that the conduction that mercury 21 is touched
The number of body 5, to determine current gear, without making scale on the pedestal 1 again.
Above-mentioned durable electric power driving switch in use, when the main sliding plug 3 is in lower limit position in sealed tube 2
When, positive terminal 62, anode connector 61 on the pedestal 1 mutually disconnect；And work as the main 3 gradual upward sliding of sliding plug, and
When mercury 21 is gradually raised upwards, the electric conductor 5 to be electrically conducted with the anode connector 61 gradually increases, according to electricity
Road relation understands that mercury 21 contacts an electric conductor 5 more per upwards, then the resistance between positive terminal 62, anode connector 61
With regard to declining a shelves, when main sliding plug 3 slides into upper extreme position, resistance is minimum between positive terminal 62, anode connector 61, electricity
Road power reaches maximum；Because during gear switch, in the absence of any rigid contact, therefore the switch is difficult to damage,
It is durable in use.
Embodiment two：
For the embodiment two shown in Fig. 2, it is with the difference of embodiment one：Also cover the top of the mercury 21
The upper sliding plug 71 that one, lid can slide in the sealed tube 2, the upper sliding plug 71 upwardly extends one section of insulation tube 7, described exhausted
The upper end of edge pipe 7 connects a top sliding plug 72；The center of upper sliding plug 71 offers to be led to what the inside of insulation tube 7 connected
Hole；The overall averag density that the upper sliding plug 71, insulation tube 7, top sliding plug 72 are formed is less than water body；The electric conductor 5 is set
In in the groove of the inwall of sealed tube 2, during so that the upper sliding plug 71 sliding up and down in sealed tube 2, not with it is described
Electric conductor 5 contacts；Upper extreme position of the upper sliding plug 71 in the sealed tube 2 is higher than the electric conductor 5 of the top.Press
According to the scheme of embodiment two, when environment temperature is higher, and the expansion of mercury 21 raises, will enter in the insulation tube 7, and
Dilation is avoided to be contacted with the electric conductor 5；Thus, without considering to make the shelves because of the change of temperature or resistance R heating
Bit switch closure or power increase automatically.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution, it should be included in the scope of the protection.
