Description
Technical field
The present invention relates to a kind of mains switch, definite a kind of rotary power switch of saying so.
Background technology
The mains switch of selling in the market and using; Mostly be the spring contact of making by copper sheet, utilize the elastic force of copper sheet to realize opening of melting point with closed, along with the oxidation corrosion or the temperature distortion of 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 safety 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 big; The rotary power switch that life-span is long, thus the present invention accomplished.
The object of the invention just provides the rotary power switch that a kind of load is big, 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 invention is made up of base, left contact, right contact, connecting rod and roller contact, and its design feature is to be provided with loam cake in the upper end of base, and loam cake is installed in the upper end of base by bolt; The left end of base is provided with left contact, and right-hand member is provided with right contact, and left and right sides contact is respectively by the upper end that is bolted to base; The bottom of left and right sides contact is connected to electric power connection line respectively, and central plate is equipped with at the middle part of left and right sides contact, and central plate is provided with connecting rod; Connecting rod is a square or circular elongate posts, and the middle part of connecting rod is installed in the upper end of central plate by bolt, and 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, and left and right sides roller contact by the movable right ends that is installed in connecting rod of bolt, is provided with electric power connection line between the roller contact of the left and right sides respectively; The right side of left side contact is provided with banking stop, and the left side of right contact is provided with the stop bit sheet, and the left and right sides of connecting rod is provided with stay thimble; The switch backguy is equipped with in the bottom side of stay thimble, and for ease of the equipped use 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, right roller contact is pressed in and has promptly connected power supply on the right contact.During like powered-down, can backguy be drawn to the lower right, make the rotation of connecting rod inhour, the roller contact of connecting rod right ends all leaves the left and right sides contact of downside, has promptly broken off power supply.
The present invention has the various control function, and its method of attachment is following:
One, a switch motion can be controlled two electrical equipment simultaneously:
1, left contact 2 is connected electrical equipment of may command with left wheel contact 3;
2, right roller contact 10 is connected another electrical equipment of may command with right contact 12.
Two, control two electrical equipment simultaneously as not needing; Also have other a kind of connected mode, exactly left wheel contact 3 and right roller contact 10 are together in series, connect left contact 2 respectively into and out of line with right contact 12; 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 present invention is simple in structure; Design ingeniously, because the contact of roller type has been replaced traditional spring leaf, thoroughly changed the defective that spring leaf is prone to aging corrosion, distortion; Prolonged the useful life of switch to greatest extent; The real at home the first that belongs to, development and use of the present invention simultaneously are with the blank of having filled up the domestic and international same industry.
Do further explain below in conjunction with accompanying drawing.
