Abstract
A kind of dual-power transfer switch, comprise switchboard, power contact, conversion equipment, it is characterized in that respectively there are two contacts of same power supply at the two ends of described switchboard, described conversion equipment is at the middle part of switchboard, conversion equipment is T-type structure, and its handle portion switches through axle, and handle portion another section after rotating shaft is connecting rod, the horizontal contact lever of connecting rod, termination is equipped with metal contact piece to feeler lever.The utility model adopts two contact, respectively has two contacts of same power supply at the two ends of switchboard, by lever operated, when feeler lever is placed in an end position, and the metal contact piece on termination and two the contact conductings of this end, this end power supply is connected; When feeler lever is placed in other end position, the metal contact piece on termination and another end two contact conductings, other end power supply is connected; When being placed in centre position, both sides not conductings.The utility model is applicable to ON-OFF control circuit technical field.
Description
Technical field
The utility model relates to ON-OFF control circuit technology, particularly relates to a kind of dual-power transfer switch.
Background technology
At present, no matter dual-power transfer switch is push-button switch switch and commutator, be all press after one end to the conducting of other one end, volume is mostly larger, contact underaction, and therefore switch cubicle is also large, thus on some control circui existing defects.
Above-mentioned existing switch in actual use, obviously has defect and exists, and need to be improved.Improving of the above-mentioned defect of the utility model thoughts is that spy concentrates on studies and coordinates repetition test, finally proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defect.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of dual-power transfer switch, to reduce volume of switch, effectively prevents loose contact, guarantees that equipment safety is produced.
For solving the problems of the technologies described above, the technical solution adopted in the utility model:
A kind of dual-power transfer switch, comprise switchboard, power contact, conversion equipment, it is characterized in that respectively there are two contacts of same power supply at the two ends of described switchboard, described conversion equipment is at the middle part of switchboard, conversion equipment is T-type structure, and its handle portion switches through axle, and handle portion another section after rotating shaft is connecting rod, the horizontal contact lever of connecting rod, termination is equipped with metal contact piece to feeler lever.
The utility model adopts two contact, respectively has two contacts of same power supply at the two ends of switchboard, by lever operated, when feeler lever is placed in an end position, and the metal contact piece on termination and two the contact conductings of this end, this end power supply is connected; When feeler lever is placed in other end position, the metal contact piece on termination and another end two contact conductings, other end power supply is connected; When being placed in centre position, both sides not conductings.
The utility model provides new solution on some commutation circuits and two-way control circuit, break ordinary tap one end to design to the thinking of the conducting of other one end, and can serve as air switch to use, when current is excessive, this switch is placed in the object that centre position realizes disconnecting.
The utility model is applicable to ON-OFF control circuit technical field.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In Fig. 1: 1-switchboard; 2-feeler lever; 3-metal contact piece; 4-connecting rod; 5-rotating shaft; 6-handle portion; 7-contact.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
embodiment:
As shown in Figure 1, a kind of dual-power transfer switch, comprises switchboard 1, power contact 7, conversion
Device, it is characterized in that respectively there are two contacts 7 of same power supply at the two ends of described switchboard 1, described conversion equipment is at the middle part of switchboard 1, conversion equipment is T-type structure, its handle portion 6 switches through axle 5, handle portion 6 another section after rotating shaft 5 is connecting rod 4, and the horizontal contact lever 2 of connecting rod 4, termination is equipped with metal contact piece 3 to feeler lever 2.
The utility model is the design of end actuating switch, respectively has two contacts 7 at the two ends, left and right of switchboard 1, when switch changer-over device is placed in left position, and two contact 7 conductings of left end, i.e. m1, m2 conducting in figure; When switch is placed in right end position, two contact 7 conductings of right-hand member, i.e. n1, n2 conducting; When being placed in centre position, both sides not conductings.
