The provided rotary knob is rotatably assembled to the shaft,
A male connector is characterized in that a fixed contact is insert-molded to the shaft, one end of which is in sliding contact with the movable contact, and the other end of which is projected from the inner end of the shaft. According to a second aspect of the present invention, in the lever combination switch according to the first aspect, when connecting the female connector to the male connector, a guide surface on which one side surface of the female connector slides is provided on the shaft, and the female connector is provided. The lower knob body is provided with an elastic locking piece that resiliently engages with the female connector when the male connector is connected to the female connector and prevents the female connector from coming off from the male connector.

[0005]

According to the first aspect of the present invention,
Since the lever has a two-body structure of a lower knob body and a shaft, a rotary knob or an insulator is attached to the shaft, and the shaft can be fitted to the lower knob body to assemble the lever. For this reason, the work of assembling parts such as the rotary knob and the insulator becomes easy. Also,
Since the male connector is formed by insert-molding the fixed contact to the shaft and projecting one end thereof from the inner end of the shaft, a cord for connecting the fixed contact to a device outside the lever and a wiring work of the cord can be omitted. Claim 2
According to the invention described in (1), since the guide surface of the female connector connected to the male connector and the retaining piece for preventing the female connector are provided, the connection of the female connector can be performed simply and reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows a lever combination switch 10 according to an embodiment of the present invention. The lever combination switch 10 includes a lever 13 including a cylindrical lower knob body 11 and a shaft 12.
A flange portion 14 is formed at an intermediate portion of the shaft 12,
Fixed contacts 15 and 16 are fixedly provided on the inner and outer surfaces of the flange portion 14. The fixed contacts 15 and 16 are embedded in the shaft 12 by insert molding, and one end is
The male connector 17 is exposed on both the inner and outer surfaces, and the other end projects from the inner end of the shaft 12. Shaft 1
A guide surface 19 with which one side surface of the female connector 18 slides when the female connector 18 is connected to the male connector 17 is provided at the inner end of the male connector 17.

The shaft 12 has a fog rotary knob 2
0 and the light rotary knob 21 are rotatably fitted. The fog rotary knob 20 is fitted from the inner end side of the shaft 12, and the movable contact 22 provided integrally contacts the fixed contact 16 on the inner end face side of the flange portion 14 resiliently. The light rotary knob 21 is fitted from the outer end side of the shaft 12, and the movable contact 23 provided integrally is resiliently slidably in contact with the fixed contact 15 on the outer end face side of the flange portion 14.

The fog rotary knob 20 is prevented from coming off by a stator 25 fixed to the shaft 12 by a locking piece 24. A moderation recess 26 is formed in the stator 25, and a moderation ball 28 urged by a moderation spring 27 loaded in a hole formed in the fog rotary knob 20 is used for the moderation recess 2.
6 is pressed against.

The light rotary knob 21 is connected to the shaft 12
Is secured by a stator 30 fixed to an outer end portion by a locking piece 29. A moderation recess 31 is formed in the stator 30, and a moderation ball 33 urged by a moderation spring 32 loaded in a hole formed in the light rotary knob 21 is in pressure contact with the moderation recess 31.

The lower knob body 11 is formed with a fitting hole 11a into which the shaft 12 is fitted.
When the female connector 18 is connected to the male connector 17, the female connector 18 is resiliently engaged with the female connector 18.
An elastic locking piece 34 is formed integrally to prevent slipping.

The structure of the lever combination switch 10 according to the present embodiment is as described above. As shown in FIG.
The light rotary knob 21, the stators 25 and 30, the moderation springs 27 and 32, the moderation balls 28 and 33, etc. are assembled, the shaft 12 is fitted into the fitting hole 11 a of the lower knob body 11, and the through-hole formed on the shaft 12 is formed. Hole 12
The pin 35 is passed through a hole (not shown) formed in the lower knob body 11 and a, and the two are integrally connected. Then, the female connector 18 is inserted through the opening 11 b formed in the lower knob body 11.
Into the male connector 17.

As described above, according to the lever combination switch 10 of the present embodiment, the fog rotary knob 20 and the light rotary knob 21
Since the rotary knob, the stators 20, 30, the moderation springs 27, 32, the moderation balls 28, 33 and the like are assembled and the shaft 12 is fitted to the lower knob body 11, the lever 13 can be assembled. 2
The work of assembling parts such as 0, 21 and stators 20, 30 becomes easy. Further, since the male connectors 17 are formed by insert-molding the fixed contacts 15 and 16 to the shaft 12 and projecting one end thereof from the inner end of the shaft 12, the fixed contacts 15 and 16 and devices outside the lever 13 are connected. The connecting cord and the wiring work of the cord can be omitted. Furthermore, since the guide surface 19 of the female connector 18 connected to the male connector 17 and the elastic locking piece 34 for preventing the female connector 17 from being provided are provided, the connection of the female connector 18 can be performed simply and reliably.
