Abstract
A four-grade rotary switch comprises a pedestal, a hob component, a straight end and a curved end, two straight ends and contacts of the straight ends, two curved ends and contacts of the curved ends, wherein one curved end and a fixing plate which has two contacts are separately fixed on the pedestal by copper rivets; a connecting sheet and a handle are fixed on a rotary wheel, a large spring is arranged inside a groove hole in the middle under the rotary wheel, and a small spring and a copper sleeve are disposed in holes on the two sides under the rotary wheel; and an in-line contacting bridge component is directly provided on a column protruding on the middle of the pedestal. The contacting bridge component is driven to act through the rotation of the handle, which makes the switch in different grades. Since the utility model has more grades than the present rotary switch, various products such as the coffee heater and so on can have more functions when employing the utility model. The utility model uses the in-line contacting bridge to replace the present concave shaped supporting point and V-shaped contacting bridge, thereby becoming simpler on the structure and reducing the assembling difficulty of the product. The utility model also can achieve the identity with the mating product on the appearance, thereby making the mating product have the aesthetic property.
Description
Affiliated technical field
The utility model relates to a kind of rotary switch.
Background technology
At present, adopt the third gear switch of " Qian " shape fulcrum and " V " contact bridge structure, mostly be seesaw (ship shape) or trigger piece (rocking arm) switch,, make switch be in the switching state respectively by pressing button or pulling the trigger piece console switch.Adopt the switch of " Qian " shape fulcrum and " V " contact bridge structure, gear is few, and the product assembly difficulty is big.
Summary of the invention
Task of the present utility model is to provide a kind of fourth gear rotary switch, it can with household electrical appliance such as the harmony in appearance of coffee heating furnace, increase aesthetic feeling, and simple in structure, assembling easily.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of fourth gear rotary switch, comprise pedestal, brandreth assembly, directly end and bent-up end, two straight ends and contact thereof, two bent-up ends and contact thereof, a bent-up end and have two contacts fixed head each be fixed in the pedestal by copper rivet, fixedly connected and handle on the swiveling wheel, down dress big spring in the intermediate groove hole, two adorn little spring and copper sheathings in lateral opening down, in-line contact bridge assembly directly is contained on the cylinder of pedestal intermediate projections.
Outside by rotation drive contact bridge assembly action to handle, make switch be in different gears.Because the utility model is more than existing rotary switch gear, adopt it that more function will be arranged as multiple products such as coffee heating furnaces.The utility model has changed " Qian " shape fulcrum and " V " shape contact bridge that existing several rotary switches use, adopt " one " font contact bridge to replace Qian " shape fulcrum and " V " shape contact bridge; become simpler on the structure thereby make; reduced the product assembly difficulty, improved the product assembling speed.The replaceable various rotary switch of the utility model makes it to reach homogeneity in appearance with auxiliary products, thereby makes auxiliary products have aesthetic property.
