Abstract
The utility model relates to an on-off state displaying switch including a switch body. The switch body is provided with a power switch and is also provided with a first detection switch, a dry cell, a first indication lamp, a second detection switch and a second indication lamp. The first detection switch, the dry cell and the first indication lamp are connected together in series and are connected with the power switch in parallel. The second detection switch is connected with the second indication lamp in series. A series circuit composed of the second detection switch and the second indication lamp are connected with an electric device controlled by the power switch in parallel. The switch body is also provided with a protection shell used for covering the first detection switch and the second detection switch. The upper end of the protection shell is hinged to the upper end of the switch body. The first detection switch and the second detection switch are both press-button-type self-locking switches. By adopting the above structure, the on-off state display switch provided by the utility model can detect on-off states of the switch in different conditions and is also dustproof and waterproof.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of break-make display switch.
Background technology
In daily life, often can run into power-off or apparatus failure; sometimes people can not make clear now whether opening of appliance switch; if in the situation of power-off; if do not have personnel seeing; after may switching on, electrical equipment is opened thereupon; waste electric energy; if apparatus failure; if now maintenance personal removes maintain electrical devices; must first go to check the situation of switch on and off; otherwise maintenance personal's personal safety is had to great hidden danger, and this loaded down with trivial details inspection job step is many, the time is long, very inconvenient.
Summary of the invention
The purpose of this utility model is to provide the quick display switch on off operating mode of a kind of energy, safe and reliable break-make display switch.
The technical scheme that realizes the utility model object is as follows:
A kind of break-make display switch, comprise Switch main body, described Switch main body is provided with mains switch, on described Switch main body, be also provided with the first sense switch, dry cell, the first indicator light, the second sense switch and the second indicator light, described the first sense switch, dry cell and the first indicator light series connection in parallel with mains switch, described the second sense switch is connected with the second indicator light, and described the second sense switch is in parallel with the electrical equipment that the series circuit of the second indicator light is controlled with mains switch.
On described Switch main body, be also provided with protective cover, the upper end of described protective cover upper end and Switch main body is hinged, after described protective cover puts down, mains switch, the first sense switch and the second sense switch is covered.
The maximum working voltage of described the first indicator light is 5V.
The maximum working voltage of described the second indicator light is 220V.
Described the first sense switch and the second sense switch are push button self-lock switch.
After adopting said structure, the utility model is the in the situation that of power-off, open the first sense switch, if the first indicator light is bright, mains switch is opening, otherwise be off-state, the in the situation that of mechanical disorder, open the second sense switch, if the second indicator light is bright, illustrate that mains switch is opening, otherwise be off-state, realize thus the detection to mains switch on off operating mode under different situations, convenient and safe reliable, protective cover has prevented that the first sense switch and the second sense switch are by the situation of false touch, also played dustproof, the effect of waterproof.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
