Specifically, be equipped with location jack, square hole for example on the reference column 44, change and set up on the core 8 and change the core jack, square hole for example, pivot 101 pegs graft in proper order and changes core jack and location jack, realize that three's circumference is spacing, synchronous rotation through this grafting, in addition, realize axial fixity through knob shell 4 and pivot 101 bolted connection. The center line of the rotating shaft 101 is specifically the rotating center line of the knob housing 4 and the rotating core 8.

As shown in fig. 15, the turn core 8 is provided with an extinction trigger key 82 so that the positional relationship between the extinction trigger key 82 and the extinction switch 11 is changed by the rotation of the turn core 8, thereby switching the on/off state of the extinction switch 11.

As shown in fig. 3, 14 and 17, the choke slider 71 of the choke switch 7 is fixed to the rotary core 8 in a sleeved manner, so that the rotary core 8 rotates the choke slider 71 to switch the open/close state of the choke switch 7.

In the combined switch in the embodiment, the starting switch 6, the flameout switch 11, the choke valve switch 7 and the oil switch 10 are directly integrated on the mounting seat 5, so that multiple functions of controlling the oil switch 10, controlling the air door, controlling the starting function and controlling the flameout function can be realized through one combined switch, and the five functions are integrated into a whole; during operation, on-off control of the flameout switch 11, the choke valve switch 7 and the oil switch 10 can be realized only by rotating the knob shell 4 and the rotary core 8, opening and closing of the starting switch 6 can be flexibly controlled by pressing the starting button 2, operation is convenient, convenience is improved, in addition, as opening and closing of the starting switch 6 are additionally controlled by the starting button 2, the rotary core 8 is not needed for control, the processing difficulty of the rotary core 8 can be simplified, and line connection is not needed between the starting switch 6 and the knob 13, and assembly efficiency can be improved; in addition, the starting function is integrated on the combined switch, the panel does not need to leave the position of the starting switch 6 independently, the space of the panel can be saved, and the attractiveness of the layout of the panel is improved.

Further, as shown in fig. 4 to 10, a button slide 41 is axially provided through the knob housing 4. The start button 2 includes a button end plate 21 and a button rod 22 fixed to one side of the button end plate 21 in the axial direction, and the mounting seat 5 and the button end plate 21 are respectively provided on both sides of the button slide 41 in the axial direction. The button stem 22 extends axially movably into the button slide 41.

Specifically, as shown in fig. 5 to 17, the knob housing 4 includes a rotating body and a positioning column 44 that fixes an axially upper end of the rotating body, and the button slide 41 is provided to penetrate the rotating body in the axial direction.

Further, the button rod 22 passes through a through hole on the generator panel to restrict the moving direction of the button rod 22 to move in the axial direction. During rotation of the knob housing 4, the button slide 41 moves relative to the button rod 22 to clear the button rod 22 in a direction perpendicular to the axial direction. That is, with the generator panel as a reference, the button rod 22 does not rotate with the knob housing 4 during the rotation of the knob housing 4 due to the limitation of the through hole on the generator panel, and the button slide 41 moves around the button rod 22 due to the arrangement of the button slide 41, and the button rod 22 does not obstruct the rotation of the knob housing 4.

In addition, the button rod 22 activates the start switch 6 by moving axially, changing the axial distance from the start switch 6. Specifically, the start switch 6 may be triggered by the depression of the button lever 22, or the start switch 6 may generate a trigger signal by detecting a change in the axial distance from the button lever 22 without contact, depending on the kind of the start switch 6. More specifically, the start switch 6 and the kill-switch 11 may be micro switches, or may be other switch structures such as hall elements and photoelectric switches.

In this embodiment, knob 13 adopts the disconnect-type design, knob shell 4 rotational operation, start button 2 presses the operation, through setting up button slide 41 on knob shell 4, and with the help of the restraint of the through-hole on the generator panel to button stem 22, can make start button 2's axial displacement, knob shell 4's rotation mutually noninterfere, can guarantee knob shell 4 and start button 2 assembly structure's compact simultaneously, be favorable to combination switch's miniaturization, prevent the maloperation.

Further, as shown in fig. 3, an elastic structure 3 is arranged between the button end plate 21 and the knob housing 4 to drive the start button 2 to axially reset, so that the automatic reset of the start button 2 can be realized, and the use of the combination switch is facilitated.
