Description
Technical field
The utility model relates to a kind of mains switch, definite says a kind of rotary power switch.
Background technology
The mains switch of selling in the market and using, it mostly is the spring contact of being made by copper sheet, utilize the elastic force of copper sheet to realize opening and closure of melting point, oxidation corrosion or temperature distortion along with copper sheet, make the elastic force of contact weaken loose contact and can not continue use, therefore it is little that this traditional mains switch ubiquity load, and fault is many, the defective that the life-span is short.
Summary of the invention
Therefore there is great demand in people to the long-lived mains switch of safe fault-free, up to now, also do not find about relevant report of the present invention, the inventor is through repeatedly development test, finally work out to have and use flexibly, safe and reliable, load is large, the rotary power switch that life-span is long, thus the present invention finished.
The purpose of this utility model just provides the rotary power switch that a kind of load is large, the life-span is long, to solve the many defectives of traditional old-fashioned switching load glitch, reduces production costs, and increases the service life.
Scheme of the present utility model is by base, left contact, right contact, connecting rod and roller contact form, its design feature is to be provided with loam cake in the upper end of base, loam cake is installed in the upper end of base by bolt, the left end of base is provided with left contact, right-hand member is provided with right contact, left and right sides contact is bolted respectively the upper end at base, the bottom of left and right sides contact is connected to respectively electric power connection line, central plate is equipped with at the middle part of left and right sides contact, central plate is provided with connecting rod, connecting rod is a square or circular elongate posts, the middle part of connecting rod is installed in the upper end of central plate by bolt, the left end of connecting rod is equipped with the left wheel contact, the right-hand member of connecting rod is provided with right roller contact, left and right sides roller contact is respectively by the two ends, the left and right sides that are installed in connecting rod of bolt activity, be provided with electric power connection line between the roller contact of the left and right sides, the right side of left contact is provided with banking stop, the left side of right contact is provided with the stop bit sheet, the left and right sides of connecting rod is provided with stay thimble, switch guy wire is equipped with in the bottom side of stay thimble, equipped use for ease of different product, also available handle replaces backguy, Drawing switch backguy left during use, connecting rod is parallel on the base, the left wheel contact of connecting rod left end is pressed on the left contact, and right roller contact is pressed in and has namely connected power supply on the right contact.During such as powered-down, backguy can be drawn to the lower right, make the rotation of connecting rod inhour, the roller contact at two ends, the connecting rod left and right sides all leaves the left and right sides contact of downside, has namely disconnected power supply.
The utlity model has the various control function, its method of attachment is as follows:
One, a switch motion can be controlled two electrical equipment simultaneously:
1, left contact 2 is connected connection with the left wheel contact, can controls an electrical equipment;
2, with right roller contact 10 be connected contact 12 and connect and can control another electrical equipment.
Two, control simultaneously two electrical equipment as not needing, also has another connected mode, exactly left wheel contact 3 and right roller contact 10 are together in series, left contact 2 and right contact 12 tap into respectively, outlet, left wheel contact 3 and right roller contact 10 have so just been eliminated in switching process, to losing of circuit, make the life-span of switch longer, performance is more stable.
The utility model is simple in structure, design ingenious, because the contact of roller type has been replaced traditional spring leaf, thoroughly changed the easily defective of aging corrosion, distortion of spring leaf, prolonged to greatest extent the useful life of switch, real genus is the first at home, and simultaneously development and use of the present utility model will have been filled up the blank of the domestic and international same industry.
Be described in further detail below in conjunction with accompanying drawing.
