Description
Technical field
The present invention relates to field of switches, more particularly, to a kind of switch of carrying magnetic damping.
Background technology
Rocker switch, also referred to as rocker type switch, rocker switch, I/O switch, power switch, its structure is identical with toggle switch,
Button handle is simply changed into ship shape.Rocker type switch is commonly used for the power switch of electronic equipment, and its contact is divided into single-pole single-throw(SPST and double-pole
Double-throw etc. is several, and some switches also carry indicator lamp.Rocker switch be applied to water dispenser, treadmill, battery truck, motorcycle, from
Electronic television machine, socket, massager etc., master are related to conventional household electrical appliance.Each the switch on wall used in family is substantially
Seesaw type concealed installation or surface mounted switch, it allows two contact instantaneous touch and disconnection by swing of the hand to button, realized to electricity
The control of source break-make, it is mechanical switch most widely used, simple to operate at present.
Conventional moving seesaw-type structural wall switch, including shell, button, dome axle, the metal terminal with contact point with
And the metal seesaw piece with contact point；Dome axle inserts the hollow posts of button inner face, and the dome portion of axle is pressed in metal seesaw piece
Centre, metal seesaw piece is horizontally disposed, and metal seesaw piece has simple support knot with the metal terminal among switch
Structure supports；The contact of seesaw piece one or both ends, it is corresponding with the contact position of metal terminal.When button pressed downwards, metal sticks up
Plate can slides along dome toward descending tilting in the reverse direction, and the contact point on metal seesaw piece with metallized metal terminals with connecing
Contacting or disconnection, realize being switched on or switched off for switch.
Prior art such as a kind of wane type switch of patent CN201610941320.6, due to being between seesaw and support member
Pressure seesaw is applied by spring, in the moment of switch on and off, seesaw can there is a situation where to shake and bounce, seesaw spring
During, the phenomenon of arcing occurs between seesaw and support member, so as to cause support member ablation.It is and in the prior art, golden
The contact point of the contact point and metal seesaw piece that belong to terminals can produce bounce in contact process.
And traditional contact point is to use single double contact point, and double contact point processing difficulties, performance is unstable, into
This height.
The content of the invention
The present invention is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of effectively to solve forceful electric power break-make
