Abstract
The invention relates to the technical field of switches, in particular to a knife switch. The knife switch comprises a contact and a contact knife, wherein the contact is fixedly connected with the contact knife; the contact is an elastic steel sheet and of Y shape; and the contact knife is a copper sheet. The knife switch provided by the invention has the advantages of simple structure, convenience in use and strong practicability; the contact is in surface contact with the contact knife so as to ensure enough contact pressure between the contact and the contact knife, avoid the deformation, heating and damage of the contact, save the maintenance time, reduce the maintenance cost and make application and promotion easy.
Description
Technical field
The present invention relates to a kind of technical field of switch, especially a kind of knife switch.
Background technology
Original knife switch contact elasticity is poor, and relatively difficulty is recovered in the distortion back, makes that contact and the contact knife contact-making surface under the "on" position is not enough, thereby causes that heating and sparking damage, and has prolonged maintenance time, has increased the expense of maintenance.
Summary of the invention
In order to overcome the deficiency that original knife switch maintenance time is long and maintenance cost is high, the invention provides a kind of knife switch.
The technical solution adopted for the present invention to solve the technical problems is: a kind of knife switch, comprise contact and contact knife, and contact is fixedly connected with contact knife.
According to another embodiment of the invention, comprise that further contact is an elastic steel sheet, and be the Y type.
According to another embodiment of the invention, comprise that further contact knife is a copper sheet.
The invention has the beneficial effects as follows: this knife switch is simple in structure, and is easy to use, practical; Contact contacts with contact knife formation face; Having guaranteed has enough contact pressures between contact and the contact knife, avoided distortion, heating and the damage of contact, has practiced thrift maintenance time; Reduce the expense of maintenance, be easy to application.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
1. contacts, 2. contact knife among the figure.
Embodiment
Like Fig. 1 is structural representation of the present invention, and this knife switch comprises contact 1 and contact knife 2, and contact 1 is fixedly connected with contact knife 2, and contact 1 is an elastic steel sheet, and is the Y type, and contact knife 2 is a copper sheet.
During use, contact 1 is an elastic steel sheet, and is the Y type, so when closing a floodgate, contact 1 can tightly be clamped contact knife 2, the 2 one-tenth faces of contact 1 and contact knife that guarantee contact, and contact-making surface increases, and has avoided contact 1 heating to damage.This knife switch is simple in structure, and is easy to use, practical; Contact contacts with contact knife formation face, and having guaranteed has enough contact pressures between contact and the contact knife, has avoided distortion, heating and the damage of contact; Practice thrift maintenance time, reduced the expense of maintenance, be easy to application.
Claims (3)
