Abstract
A rotary switch comprises a fixed base, a fixed contact piece, a movable upper cover and a movable contact piece, wherein a rolling conductive mechanism is arranged between the fixed contact piece and the movable contact piece. The bottom surface of the movable upper cover is provided with a positioning groove and a boss, and the movable contact piece is fixed on the boss through a screw; a spring is pressed between the movable upper cover and the movable contact piece, and one end of the spring is fixed in the positioning groove. The fixed contact is arranged on the fixed base, and the fixed base is buckled with the movable upper cover through buckling positions, so that the movable contact, the roller bracket, the roller and the fixed contact are pressed in pairs. The utility model discloses a set up the electrically conductive mechanism of roll between rotary switch's fixed contact and movable contact, reduced the wearing and tearing of electrically conductive contact surface, the operation is more smooth and easy. The spring on the rolling conductive mechanism makes the contacts between the conductive parts automatically complement and contact to prevent the ignition phenomenon. The structure is simple and reasonable, the service life is long, and the safety and the reliability are realized.
Description
Technical field
The utility model relates to a kind of rotary switch, particularly a kind of rotary switch that is used for 360 degree motions on the household electrical appliance.
Background technology
Power supply docking adapter in the rotary switch of existing 360 degree motions adopts sliding friction mostly, and it is more serious to wear and tear, and occurs the contact spark phenomenon frequently.China Patent No. 200520054383.7 discloses a kind of rotary switch, comprise that a housing, a power input part that is installed on the housing divide and a power supply output, the power supply output comprises a plurality of conductive base pins, and the power input part branch selectively is electrically connected with above-mentioned a plurality of conductive base pins.The contact chip of this structure contacts electrical connection with conductive base pin by point, and spark phenomenon easily takes place when rotation is excessively arrived another conductive base pin its contact chip.The long-term use, contact chip is because the influence of high temperature when being struck sparks deforms even operational failure.
The utility model content
It is a kind of simple and reasonable that the purpose of this utility model is intended to provide, and the smooth down grinding of turning round is decreased little, and the rotary switch of long service life is to overcome weak point of the prior art.
A kind of rotary switch by this purpose design comprises firm banking, fixed touch plate, movable loam cake and movable contact flat, and its architectural feature is to be provided with the rolling conductive mechanism between fixed touch plate and the movable contact flat.
Described rolling conductive mechanism comprises the rolling wheel support that is arranged on the movable contact flat, and rolling wheel support is arch, and both sides are provided with coaxial circular hole with supporting rollern.
Described movable loam cake bottom surface is provided with location notch and boss, movable contact flat by screw on boss; Be crimped with spring between movable loam cake and the movable contact flat, spring one end is fixed in the location notch.
Described fixed touch plate is more than one donut, is arranged on the firm banking, and leg is stretched out from firm banking.
Described firm banking side is provided with button bit, and button bit fastens firm banking with movable loam cake, and makes crimping in twos between movable contact flat, rolling wheel support, roller and the fixed touch plate.
Described movable contact flat, rolling wheel support, roller and fixed touch plate are made by electric conducting material.
This rotary switch has reduced the wearing and tearing of conductive contact surfaces by the rolling conductive mechanism is set between fixed touch plate and the movable contact flat, and it is more smooth and easy to turn round.Spring on the rolling conductive mechanism makes the automatic cover contact in the contact between the electric-conductor, prevents spark phenomenon.It is simple and reasonable, and long service life is safe and reliable.
