Portion's rotation, two turning end of button 3 press energization end 2 under being respectively and lower press powers off end 4, and the lower section of button 3 is equipped in pedestal 1
The U-bracket of interior fixed setting, bracket have fore-stock plate 81 and after-poppet plate 82, and button 3 presses the bottom at energization end 2 under it
Drive block 9 is connected, for drive block 9 between front and back support plate, the front and back end of drive block 9 is equipped with pin shaft, and pin shaft activity passes through branch
The guide groove 11 that frame plate 8 is equipped with, guide groove 11 is in vertically arranged, and the bottom of guide groove 11 is equipped with bending part 12, drive block 9
Lower section is equipped with pressing plate 13, is connected between drive block 9 and pressing plate 13 by transmission arm 10, and the left end of pressing plate 13 is reset spring 25
Upward picking-up is hooked, the left end of pressing plate 13 is equipped with baffle 20, and the swingable setting of baffle 20 is simultaneously carried out after swing by torsional spring 23
It resets, the upper end of baffle 20 is connect by drive rod 22 with electromagnetic actuator device 21, and drive rod 22 described here is transmission iron
Core, baffle 20 are equipped with and compress platform 24, and when the switch is closed, the left end bottom of pressing plate 13 offsets with platform 24 is compressed, pressing plate
Balladeur train 14 is equipped with below 13 right end, balladeur train 14 makees up and down setting, the right end top of the bottom of balladeur train 14 and dynamic touch panel 17
Contact, dynamic 17 left end of touch panel, which can move up and down, to be threaded through on guide post 19, and the bottom for moving 17 middle section of touch panel is equipped with spring 18, moves touch panel
17 right end bottoms connect moving contact 16, and the lower section of moving contact 16 is equipped with static contact 15, when pressing energization end 2 by lower button 3 lower,
Moving contact 16 is contacted with static contact 15, and spring 18 is in impaction state, and pin shaft is fastened in the bending part 12 of card holding trough 11.
The working principle of the invention patent is：When needing makes to close the switch, lower by lower button 3 presses energization end 2, drives
Drive block 9 moves downward, and drive block 9 drives balladeur train 14 by right end downward actuation of the transmission arm 10 with dynamic pressure plate 13, pressing plate 13
It pushes, balladeur train 14 drives the right end downward actuation of dynamic touch panel 17, so that moving the moving contact 16 of 17 right end bottom of touch panel and being located at it
The static contact 15 of lower section contacts, and realizes that the closure of switch is powered, due to moving the right end downward actuation of touch panel 17, so that dynamic touch panel 17
The spring 18 of bottom is compacted, and the spring 18 being compacted can be supplied to 17 1 upward reaction forces of dynamic touch panel, this is upwards
Reaction force successively by dynamic touch panel 17, balladeur train 14, pressing plate 13, transmission arm 10, be ultimately transferred to drive block 9, transmitting
Cheng Zhong, since the right end of pressing plate 13 is by upward reaction force, so the left end bottom of pressing plate 13 can compress contact baffle 20
Side compresses platform 24, so that pressing plate 13 will not be influenced again by reaction force and continue to overturn, guarantees upward reaction force
Pressing plate 13 can be passed through and be transferred to drive block 9, when this upward reaction force is sent to drive block 9, on drive block 9
Pin shaft be placed exactly in the bending part 12 of 11 bottom of guide groove, the pin shaft reaction force upward by this is influenced so that
Pin shaft is fastened in the bending part 12 of 11 bottom of guide groove, realizes locking when closing the switch.
When switch is in above-mentioned closed-lock state, but appearance is leaked electricity, electric current can pass through electromagnetic actuator device
21, electromagnetic actuator device 21 drives baffle 20 to swing to the left by drive rod 22, so that the left end of pressing plate 13 loses and baffle 20
On the contact that compresses for compressing platform 24, pressing plate 13 is influenced by upward reaction force and continues to overturn, then upward
Reaction force cannot be passed up to drive block 9 again, and pin shaft fixation cannot also be made to be fastened on the curved of 11 bottom of guide groove
In folding part 12, pressing plate 13, which also can not be just continuously applied, gives balladeur train 14 1 downward active forces, moves touch panel 17 at this time no longer by under
The effect of pressure, the spring 18 of dynamic 17 bottom of touch panel being compacted just will drive dynamic touch panel 17 and be lifted up, so that moving contact 16
It is separated with static contact 15, realizes the disconnection of switch, guarantee the safety utilization of electric power of switch, after switching disconnection, electromagnetic actuator device 21
No longer apply active force to drive rod 22, baffle 20 is swung to the right by 23 reset response power of torsional spring to be resetted, while driving biography
Lever 22 resets, and reset spring 25 holds the left end of pressing plate 13 so that the left end of pressing plate 13 be located at baffle 16 keep out platform 20
Top, to guarantee going on smoothly for next manual closing switch.
When needing disconnects switch manually, apply downward active force to the lower power-off end 4 of pressing of button 3, so that transmission
Pin shaft on block 9 is deviate from out of 11 bottom of guide groove bending part 12, and drive block 9 is driven to move up, and moves touch panel 17 no longer at this time
By the effect of lower pressure, the spring 18 of dynamic 17 bottom of touch panel being compacted drives dynamic touch panel 17 to be lifted up, so that moving contact 16
It is separated with static contact 15, realizes the disconnection of switch.
