2nd, background technology
The word explanation of switch is opening and closing.It also refers to that one can make open circuit, make current interruptions or make
It flows to the electronic component of other circuits.Most common switch is the electromechanical equipment for allowing people to operate, wherein having one or several electricity
Sub- contact.The " closed " closed of contact represents electronic contact conducting, it is allowed to which electric current flows through；" open circuit " open of switch represents electricity
Sub- contact is not turned on forming open circuit, does not allow electric current to flow through.
And change-over switch is a kind of to be available for two-way or two-way above power supply or the device for switching of load transfer.Change-over switch
Formed by more piece contact combinations, in the electrical apparatus, be used for non-frequently connecting with disjunction circuit, switch on power and load,
Measure three-phase voltage and control rotating and star delta starting of low capacity asynchronous motor etc..These parts pass through bolt
Fasten as an entirety.
But in life, the conversion of circuit is carried out by electromagnetic relay sometimes, electromagnetic relay is a kind of
Electronic control device, there is control system to be also known as input circuit and be also known as output loop by control system for it, be commonly used to certainly
In dynamic control circuit, it is actually to be gone to control larger current, one kind of higher voltage with less electric current, relatively low voltage
" automatic switch ".Therefore play automatically adjust in circuit, safeguard protection, the effect such as change-over circuit.When electromagnetic relay works it
Afterwards, circuit produces conversion, but the circuit before some working environments need to be switched to is operated, or work at present electricity
Road produces failure, it is necessary to quickly disconnect, and now, mode only manually could realize circuit switching, and electromagnetic relay
Manual switching circuit is very hard, and the degree of difficulty that operates is bigger, takes time and effort.
It quickly can directly switch electromagnetic relay circuit on the market now, manual switching circuit can be carried out,
Easy to operation, manual circuit switching switch easy to use is not found also, is had to be developed.
3rd, utility model content
In order to overcome the weak point of available circuit control element, the utility model provides a kind of manual circuit switching and opened
Close.
What the technical solution of the utility model was realized in.
A kind of manual circuit switching switch of this programme, including shell and electromagnetic relay, the electromagnetic relay with it is outer
Shell inner bottom part is fixedly connected, and the electromagnetic relay includes magnet coil, movable contact and stationary contact, and the movable contact is located at electromagnetism
Between coil top and stationary contact bottom；
The cover top portion is provided with through hole, and connecting rod is provided with the through hole, is provided with knob at the top of the connecting rod, institute
State connecting rod bottom and be provided with the buffer head for making movable contact be separated with stationary contact for depressing movable contact；The knob bottom is close
Locating rod is provided with the position of connecting rod, the outer casing top surface is provided with the positioning hole being used cooperatively with locating rod.
Spring is provided with connecting rod between the knob bottom and cover top portion, the spring is all the time in stretching shape
State, the spring top are fixedly connected with knob bottom, and the spring bottom end is fixedly connected with outer casing top surface.
It is of the present utility model to be beneficial in that：The device structure is simple, easy to use, quickly can directly switch electricity
Magnetic relay circuit, manual switching circuit can be carried out, it is easy to operation.
4th, illustrate
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
5th, embodiment
Brief description is made to specific embodiment of the present utility model below in conjunction with the accompanying drawings.
A kind of manual circuit switching switch as depicted, including shell 1 and electromagnetic relay 2, the electromagnetic relay 2
It is fixedly connected with the inner bottom part of shell 1, the electromagnetic relay 2 includes magnet coil 3, movable contact 5 and stationary contact 4, described dynamic tactile
Point 5 is between the top of magnet coil 3 and the bottom of stationary contact 4；
The top of shell 1 is provided with through hole 6, and connecting rod 7 is provided with the through hole 6, and the top of connecting rod 7 is provided with rotation
Button 9, the bottom of connecting rod 7 are provided with the buffer head 8 for making movable contact 5 be separated with stationary contact 4 for depressing movable contact 5；It is described
The bottom of knob 9 is provided with locating rod 11 on the position of connecting rod 7, and the top surface of shell 1 is provided with to be coordinated with locating rod 11
The positioning hole 12 used.
Spring 10 is provided with connecting rod 7 between the bottom of knob 9 and the top of shell 1, the spring 10 is in all the time
Extended state, the top of spring 10 are fixedly connected with the bottom of knob 9, and the bottom of spring 10 is fixedly connected with the top surface of shell 1.
The course of work of this example：When using the utility model, magnet coil 3 is connected in the first circuit, stationary contact
Point 4 is connected on second circuit, and when the first circuit normal work, magnet coil 3 works, and movable contact 5 is attracted by magnet coil 3
Get off, movable contact 5 is separated with stationary contact 4, when the first circuit does not work, the resilience of movable contact 5 contacts with stationary contact 4, makes second
Circuit communication, second circuit start to run well.
Now, if it is desirable, for example：When overhauling first line or the quick disconnection of second circuit needs, turn
Dynamic knob 9, connecting rod 7 rotate in through hole 6, locating rod 11 is turned on positioning hole 12, then the insertion of locating rod 11 positioning
In hole 12, move down connecting rod 7, the buffer head 8 of the bottom of connecting rod 7 depresses movable contact 5, movable contact 5 is divided with stationary contact 4
From realization attracts movable contact 5 to separate equivalent effect with stationary contact 4 after being powered with magnet coil 3, and movable contact 5 divides with stationary contact 4
From rear, second circuit disconnects, and now the spring 10 of extended state can avoid connecting rod 7 up and down, realizes the longitudinal direction of connecting rod 7
The purpose of positioning, when needing to connect second circuit again, upper pull-turn button 9, connecting rod 7 is moved up, while make locating rod 11 de-
Go out in positioning hole 12, and turning knob 9, then unclamp, the spring 10 of extended state effectively avoids connecting rod 7 from voluntarily rotating, and makes
Locating rod 11 will not rotate, more stable, now pressure of the movable contact 5 due to losing buffer head 8, voluntarily resilience, movable contact 5 with
Stationary contact 4 contacts again, realizes that second circuit connects, can realize when magnet coil 3 loses effect in two circuits
Between independently switch, use simpler convenience.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
