Embodiment, belongs to the scope of protection of the invention.
As Figure 1-Figure 5, the invention discloses a kind of electromagnetic switch of manual-automatic integrated, including：Fixed base 1, line
Iron core 7, first switch circuit 2 and interior pendulum assembly 3 are enclosed, wherein, fixed base 1 plays branch as the basis of whole electromagnetic switch
Support and the effect of mounting bracket；Iron-core coil 7 for being connected with DC circuit is arranged on the fixing card 5 of fixed base 1；First
On-off circuit 2 is used to be connected with external circuitses, and external circuitses are the circuit that the electromagnetic switch needs to control；Interior pendulum assembly 3
The iron core of permanent magnet 17 and 12 and iron-core coil 7 can produce magneticaction, i.e., can attract each other or mutually exclusive, iron core
The first connection piece 18 of interior pendulum assembly 3 can turn on first switch circuit 2 during the iron core adhesive of coil.During work, by coil
Iron core 7 is connected with DC circuit, and now, iron core can produce a stabilizing magnetic field so that iron core one end is that N poles one end is S poles, iron
The N poles of core can repel with the N poles of the first permanent magnet 17, and the S poles of iron core can attract with the N poles of permanent magnet 17, put interior pendulum assembly
Dynamic, when iron core and 12 adhesive of permanent magnet, the first connection piece 18 is away from first switch circuit 2 so that first switch circuit 2 can not
Connection, now electromagnetic switch disconnection；When iron core and the first permanent magnet 12 repel, interior pendulum assembly 3 is to the side away from iron-core coil 7
To swing so that the first connection piece 18 is close to first switch circuit 2, until the first connection piece 18 and first switch on-off circuit 2
Laminating, first switch circuit 2 is connected, electromagnetic switch conducting, makes external circuitses formation loop；When the voltage reversal of DC circuit
When, then interior pendulum assembly backswing, so as to realize that electromagnetic switch disconnects and turned on.
Electromagnetic switch disclosed herein can make interior pendulum assembly 3 swing and controlled to electromagnetic switch by way of power supply
System, it is not necessary to which operator's pressing reaches the state for changing electromagnetic switch to change the state of elastic component, thus it is guaranteed that electromagnetism is opened
The quality of pass, to extend the service life of electromagnetic switch.In addition, the electromagnetic switch in the application can also realize manual control, with
Ensure electromagnetic switch normally using when that can not be controlled by power supply mode.
In a further embodiment, the electromagnetic switch also includes the second switch circuit 4 being arranged in fixed base, should
Second switch circuit 4 is used to be connected with test circuit, and test circuit is to detect the circuit of the electromagnetic switch state.In order to realize pair
The control of second switch circuit 4, the interior pendulum assembly has the second permanent magnet with the iron core generation magneticaction of iron-core coil 7
17, and connect piece 11 with can connect second switch circuit 4 second.In order to ensure the interior pendulum assembly 3 of the electromagnetic switch
What can be stablized is waved, and the magnetic force direction of the second permanent magnet 17 and iron core is set to the magnetic force with the first permanent magnet 12 and iron core
In the opposite direction, with ensure it is interior pendulum assembly 3 swung back and forth between first switch circuit 2 and second switch circuit 4.
During work, after iron-core coil 7 is connected by coil electrode 6 with DC circuit, the first permanent magnet 12 and iron core phase
Reprimand and the second permanent magnet 17 then with iron core it is attracting when, interior pendulum assembly 3 is then swung to the direction of the first permanent magnet 17, until second forever
Magnet 17 is pulled together with iron core, now, and the first connection piece 18 turns on first switch circuit 2, electromagnetic switch conducting, and the
Two connection pieces 11 are away from second switch circuit 4, and second switch circuit 4 is not turned on, and test circuit can not form loop, now operate
The state of test circuit is denoted as electromagnetic switch conducting state by person；When the voltage reversal of DC circuit, the first permanent magnet 12 with
Iron core is attracting, and the second permanent magnet 17 then repels each other with iron core, and interior pendulum assembly 3 is swung to the direction of the second permanent magnet 17, the first connection
Piece 18 then disconnects away from first switch circuit 2, i.e. electromagnetic switch, and the second connection piece 11 turns on second switch circuit 4, warns
Operator's state disconnects for electromagnetic switch.To sum up, interior pendulum assembly 3 is put between first switch circuit 2 and second switch circuit 4
Dynamic, when being rocked to first switch circuit 2, electromagnetic switch conducting, second switch circuit 4 is disconnected, and detection means is not turned on；When
When being rocked to second switch circuit 4, second switch circuit 4 is turned on, and detection means conducting, first switch circuit 2 is not turned on, the electricity
Magnetic switch disconnects.
By setting second switch circuit 4, the person of being convenient to operation detects the current state of the electromagnetic switch, as disconnects shape
State or conducting state, the problem of preventing maloperation extend the service life of the electromagnetic switch.
In addition, after iron core and the adhesive of the first permanent magnet 12, if disconnecting DC circuit, under the magneticaction of permanent magnet, the
One permanent magnet 12 also may proceed to absorption with iron core, and not turn off, and similarly, after iron core and the second 17 adhesive of permanent magnet, not change
It will not also be disconnected during time variant voltage direction, therefore, a direct power supply can be avoided, reach the purpose of energy-conservation.When need change electromagnetic switch
During state, then only need to change the voltage direction of the pulse of one fixed width, it is not required that maintain a direct-furnish of DC circuit
Electricity.
In the particular embodiment, indicator lamp is connected in test circuit, it is convenient to realize warning function by indicator lamp
Operator observes, i.e., when indicator lamp is bright, then the electromagnetic switch is off-state, when indicator lamp does not work, then the electromagnetic switch
For conducting state.A kind of specific alarming device is merely provided in the application, in practice can according to the need for difference in inspection
Survey on device and connect different instruction devices, and in protection domain.
The structure of disclosed second switch circuit 4 in the application specifically includes two left of shell fragment electrodes, the two bullets
The positive pole and negative pole of connecting test circuit are distinguished in right contact 15 of left of plate electrode, in order to realize electromagnetic switch state-detection
Effect, left of the two shell fragment electrodes are not connected, it is necessary to be connected the two shell fragment electrodes for left by the second connection piece 11.
When the second connection piece 11 is not connected with two left of shell fragment electrodes, detection circuit is not turned on, and illustrates that first switch circuit 2 is led
Logical, electromagnetic switch is conducting state.
On the basis of above-mentioned technical proposal, it is right that first switch circuit 2 disclosed herein includes two shell fragment electrodes
Piece, right of the two shell fragment electrodes can be turned on by the first connection piece 18,16 points of the left contact of two right of shell fragment electrodes
Not Lian Jie external circuitses positive pole and negative pole.In order to realize the effect of electromagnetic switch, right of the two shell fragment electrodes are not connect,
Need to connect the two shell fragment electrodes for right by the first connection piece 18.When the first connection piece 18 is right not with two shell fragment electrodes
When piece is connected, external circuitses are not turned on, and illustrate that first switch circuit 2 disconnects, electromagnetic switch is off-state, now, and second opens
Powered-down road 4 is turned on, and detects circuit communication.
Merely provide the concrete mode of a kind of first switch circuit 2 and second switch circuit 4 herein, its core for this two
