Description
Technical field
A kind of switch is the utility model is related to, more particularly to a kind of sound pick-up shift switch.
Background technology
Sound pick-up shift switch is used to adjust the audio signal from sound pick-up output, reaches the purpose of regulation tone color.Tradition
Sound pick-up shift switch include top cover, housing, printed circuit board, handle, rotating wheel and contact, contact is typically using 4 forks or 3
The spring leaf of fork, spring leaf are provided with contact, and two spring leafs are symmetrically mounted on rotating wheel, and handle control rotating wheel rotates
And contact is moved along the path on printed circuit board, reach the purpose of gearshift.But the shift switch of this structure is being controlled
During spring leaf movement processed, it may be rocked due to the bifurcated piece on spring leaf and make contact and printed circuit board loose contact, shadow
Ring the normal work of sound pick-up.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of simple in construction, easy to use, and it is more stable to work
Sound pick-up shift switch.
The technical scheme that the utility model is taken to achieve the above object is：
A kind of sound pick-up shift switch, the switch include housing, gearshift governor motion and circuit board are set on the housing,
The gearshift governor motion is included on housing and sets back shroud, formed with operating space between described back shroud and housing,
Power transmission shaft is set in described operating space, corresponding axle sleeve is provided with the power transmission shaft, is arranged with the axle sleeve
Switch knob interlocks with it, rotating wheel is also arranged with the axle sleeve, the rotating wheel both sides are respectively arranged with contact chip, described
Circuit board both sides are provided with several contact points, and the contact chip makes it be offseted with contact point by rotating wheel rotation, described bonnet
With being hinged in the middle part of rocking arm on plate, by setting spring to be connected with back shroud, the other end is provided with for one end of the rocking arm
Position-limited wheel, the switch knob are provided with the stopper slot to match with position-limited wheel.
Further, it is provided with deflating cap on the switch knob.
In the utility model, it is connected due to rocking arm by spring with back shroud and position-limited wheel is set on rocking arm, opened
Close and corresponding stopper slot be set on handle, contact can be made with smooth rotation all the time in rotating wheel rotation process, so as to
Circuitry in close contact on circuit board, bifurcated spring leaf is avoided in background technology because bifurcated piece rocks and caused contacts not
The problem of good.

Embodiment
Specific embodiment of the present utility model is made a detailed explanation below in conjunction with the accompanying drawings.
As Figure 1-4, a kind of sound pick-up shift switch, the switch include housing 1, gearshift regulation are set on the housing
Mechanism and circuit board 2, the gearshift governor motion is included in setting back shroud 3 on housing, between described back shroud and housing
Formed with operating space, power transmission shaft 4 is set in described operating space, corresponding axle sleeve 5 is provided with the power transmission shaft,
Switch knob 6 is arranged with the axle sleeve 5 to interlock with it, and deflating cap 7 is provided with the switch knob 6, is gone back on the axle sleeve 5
It is arranged with rotating wheel 8, during work, toggle switch cap 7 makes switch knob 6 drive power transmission shaft 4 to rotate, so as to drive rotating wheel 8 one
Rotation is played, the both sides of rotating wheel 8 are respectively arranged with contact chip 9, and the both sides of circuit board 2 are provided with several contact points 10, described
Contact chip 9 by rotating wheel 8 rotation it is offseted with contact point 10, so as to complete to shift gears, on described back shroud 3 with rocking arm 11
Middle part be hinged, by setting spring 12 to be connected with back shroud 3, the other end is provided with position-limited wheel for one end of the rocking arm 11
13, the switch knob 6 is provided with the stopper slot 14 that matches with position-limited wheel 13, during gearshift, rotating wheel 8 with movable contact spring 9 with not
Same contact 10 is in contact, and in the presence of position-limited wheel 13, stopper slot 14 and spring 13, makes contact 9 with the rotation process of rotating wheel 8
In smooth rotation all the time, so as to be contacted with the circuitry in close on circuit board 2.
