Detailed description of the invention
With concrete better embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, a kind of rocker switch with silencing function, including button 1, pressing plate 2, seesaw, after
Core 4 and shell 5.
Button is arranged on the top of shell, and button can carry out left and right in the enclosure and press.
Button includes face shield 11, slide block 12 and slide bar 13.
Face shield bottom opening is arranged, and face shield includes left leg 112 and the right lower limb 113;The bottom of left leg and the right lower limb is each
It is provided with at least one noise reduction salient point 111;The bottom of left leg and the right lower limb is preferably each provided with two noise reduction salient points.
Each noise reduction salient point all can contact with outer casing inner wall face, and each noise reduction salient point is the most preferably in wedge structure.From
And, when pressing when about button, bottom face shield, the contact area with shell is little, and noise is little.
Further, the bottom of each noise reduction salient point is all preferably provided with elastic wear-resisting layer, outside contacting with noise reduction salient point
Shell is preferably steel frame construction.Thus while eliminating the noise further, wear-resistant, service life is long.
Slide block 12 is coaxially fixed on the bottom surface of face shield, is preferably interlockingly connected with face shield by button bit.The bottom of slide block
Being provided centrally with center projection 121, the bottom of center projection is fixedly installed slide bar 13.Slide bar is preferred with the bottom of center projection
For removably connecting, as threaded, particularly as follows: the bottom of center projection is provided with female thread, the top of slide bar is arranged with interior
The external screw thread that screw thread matches.
Above-mentioned pressing plate plays the effect formed a connecting link, and pressing plate top carries out axle position by central shaft hole with slide block and is connected,
Pressing plate bottom is fixing with rear core to be connected, and is preferably interlockingly connected, and then it is fixing that the copper cash etc. of rear in-core carries out pressing.
The left and right sides of pressing plate is each provided with a positioning convex 22, and the face shield lower surface being positioned at slide block both sides is respectively arranged
There is a detent 114 that can match with positioning convex.Two above-mentioned positioning convex are preferably centered by central shaft hole, right
Claim to arrange.
The most preferred hemispherical structure of each positioning convex, each detent is the most hemispherical.
Above-mentioned positioning convex and the setting of detent, when pressing when about button, can make face shield coaxial with pressing plate
Position, accurate positioning, it is to avoid face shield such as swings at the phenomenons such as the loose contact caused.
Rear core is arranged on the lower section of pressing plate, and shell connects fixing to rear core and pressing plate.
Rear core top side is provided with stationary contact.
Seesaw includes movable contact spring and riser, and movable contact spring includes U-shaped chute, two disconnection salient points upwards swelling and dynamic touch
