Abstract
The utility model discloses a double-phase switch, belonging to a safety device for a circuit, mainly composed of two single-phase switches which are combined and linked. The utility model is characterized in that the two single-phase switches are installed on the same insulating plastic base; the two single-phase switches are connected into a whole by an insulating plastic member and are controlled by an operating lever (or a draw rod) The utility model can overcome the defect that the live wire and the ground wire of an illumination or electric apparatus circuit are easy to be installed by mistake, can eradicate the human casualty accident caused thereby, and can replace the existing single-phase switches.
Description
The utility model relates to a kind of Double-phase switch, and it belongs to a kind of circuit safety device, mainly comprises the architectural feature of two single-phase switch combinations of ground wire and live wire interlock.
At present, the line switching of extensive use has backguy and seesaw type etc., adopts the open and close of single-phase control electric light and electrical equipment.Be that switch must be installed on the live wire in theory, but in real life, because the quality of installation personnel and operational procedure are observed problems such as not tight, the probability that causes live wire can not enter switch reaches about 50%, for human casualty accident has been buried hidden danger, therefore countless human casualty accident has appearred.Lesson is heavy, must cause that people pay much attention to.
The purpose of this utility model is the drawback that will overcome above-mentioned live wire and the easy misloading of ground wire, eradicates the human casualty accident that causes therefrom, and a kind of Double-phase switch is provided.
The purpose of this utility model realizes by following measure: two single-phase switchs are installed on the same ambroin base, join together with an ambroin spare between two single-phase switchs, control opening or closing of live wire and ground wire respectively simultaneously by operating lever (or pull bar).
Be from the above advantage of the present utility model: the circuit installation and maintenance are convenient, close Double-phase switch after, electrical equipment is all not charged, safe and reliable.
Concrete device of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the new Double-phase switch vertical view that proposes of this practicality;
Fig. 2 is in link tester electricity condition end view according to the new Double-phase switch that proposes of this practicality;
Fig. 3 is in circuit off-state end view according to the new Double-phase switch that proposes of this practicality.
Below in conjunction with accompanying drawing, describe the details and the working condition of concrete device of the present utility model in detail.
As seen from Figure 1, the utility model is mainly formed by 1, the 2 combination interlocks of two single-phase switchs, respectively two single- phase switchs 1,2 are installed on the same ambroin base 3, join together with an ambroin spare 4 between two single- phase switchs 1,2, by operating lever (or pull bar) 5 controls.
As seen from Figure 2, when operating lever (or pull bar) 5 drive two single- phase switchs 1,2 to the bottom right by the time, live wire 6 and ground wire 7 are connected respectively simultaneously.
As seen from Figure 3, when operating lever (or pull bar) 5 drove two single- phase switchs 1,2 to upper right pull-up, live wire 6 and ground wire 7 disconnected respectively simultaneously, and at this moment, electric light or electrical equipment 8 are not charged, for safety, add ambroin lid 9 on the base 3.The utility model can be made stay-supported or seesaw type etc.
