Specific embodiment
Hereinafter, for a more detailed description to the utility model with embodiment combination attached drawing.This embodiment is only to this
The description of utility model preferred forms, does not have any restrictions to the scope of the utility model.
As shown in Figures 1 to 4, a kind of contact switch, including push rod 1 and shell 2,1 one end holding fixed button of push rod
11,1 other end of push rod protrudes into shell 2 and is equipped with regulating part 12, is equipped with output chip a3 and output chip b4, Yi Jishe in shell 2
It is placed in the circuit control panel 7 of 12 side of regulating part；Two connectors being disposed adjacent are equipped between output chip a3 and regulating part 12
5, it is equipped with spring a13 between connector 5 and shell 2, tension spring 6 is equipped between connector 5 and output chip a3,5 one end of connector is set
There are electric contact a51, the output chip b4 to be equipped with the electric contact b41 matched with electric contact a51.
5 other end of connector contradicts regulating part 12, and the end is equipped with the bending section 52 of hook-shaped.
Regulating part 12 is equipped with the first notch 14 and the second notch 15, the first notch 14 to the second close to the side of connector 5
Notch 15 is close to bending section 52.
It is equipped with firmware 16 between button 11 and shell 2, the holding block 17 of holding firmware 16 is equipped in button 11, is consolidated
16 one end of part contradicts 2 surface of shell, and spring a13 is equipped between firmware 16 and button 11.Firmware 16 is protected using spring
The filling for contradicting 2 surface of shell is held, the effect of firm button 11 is played during button 11 pushes.
Spring b18 is equipped between connector 5 and shell 2.The reset power of button 11 is provided, when release button 11, is utilized
The elastic reset button 11 of spring.
Specific working principle are as follows:
It is pushed by 11 driving push rod 1 of push button, changes the relative position of regulating part 12 and circuit control panel 7, spring
A13 compresses simultaneously, and when the first notch 14 of regulating part 12 is more than bending section 52, the bending section 52 of connector 5 loses regulating part
12 overhead, tension spring 6 pull connector 5, fall into the bending section 52 of connector 5 in first notch 14, the electric contact of connector 5
A51 and electric contact b41 are inconsistent, connection circuit；
Further, continue to push button 11, it is adjacent when the second notch 15 being made to be more than the bending section 52 of adjacent connections 5
The bending section 52 under the action of tension spring 6 of connector 5 is fallen into the second notch 15, the electric contact a51 and electric contact of adjacent connections 5
B41 is inconsistent, at this point, output chip b4 stops output.
Further, when release button 11, spring a13 resets, and pushes regulating part 12 to move to 1 direction of push rod, directly
It, will be curved under the action of spring a13 to 2 inner wall of shell, the first notch 14 and the second notch 15 is contradicted when by bending section 52
Tune 52 ejects in the first notch 14 and the second notch 15, and electric contact a51 is made to be detached from the conflict with electric contact b41.
By 11 driving push rod 1 of button, make it that adjustment sheet 12 be pushed to move up and down relative to circuit control panel 7, circuit control
There are the resistor discs of different resistance for different positions in making sheet 7, control electric tool by the variation of resistance value in moving process
Revolving speed.Specifically, the main function of electric tool switch is first to power on the motor of electric tool to slowly run, so
It is raised speed afterwards by alignment circuit, rotates motor at full speed.
By adopting the above-described technical solution, a kind of contact switch, is realized by the cooperation of connector 5 and regulating part 12
Output chip a3 is connected to output chip b4's, and the control of circuit, the utility model are realized in the cooperation of regulating part 12 and circuit control panel
Structure is simple, easy for installation, the effective solution control problem of electric tool.
Obviously, above-described embodiment is just for the sake of clearly illustrating done citing, and does not limit the embodiments.
To those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And obvious variation extended from this or change
It moves still in the protection scope of the utility model.
