On bottom surface, the bottom centre of slide block is provided with center projection, and the bottom of center projection is fixedly installed slide bar.
Pressing plate be provided centrally with central shaft hole, slide bar in the central shaft hole of pressing plate through and can swing.
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
Point；The bottom of riser is fixing with rear core to be connected, and the top of riser is fixing with the bottom centre of U-shaped chute to be connected；Energy bottom slide bar
Coordinate with U-shaped slide.
Two disconnect salient points and are symmetricly set on the both sides of U-shaped chute, and movable contact is arranged on the side tail end of movable contact spring, can be with
Stationary contact contacts cooperation.
The bottom of described slide bar and center projection is for removably connecting.
Described slide bar is connected with the bottom thread of center projection.
The bottom of described center projection is provided with female thread, and the top of slide bar arranges the external screw thread matched with female thread.
After this utility model uses said structure, when movable contact and stationary contact phase adhesion, button press, button will drive
Slide block rotates along the central shaft hole of pressing plate, and after rotating to certain angle, slide block is sent out with the disconnection salient point on seesaw
Raw interference, at this moment the power by applying on button forces seesaw action, just can force to separate movable contact with stationary contact.

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 forced switching-off function, including button 1, pressing plate 2, sticks up
Plate, rear 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
