Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary switch suitable as an automobile door lock detection switch.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a rotary switch of this type has an actuating member 3 having a straight line portion 1 and a bent portion 2 formed by bending an end portion of the straight line portion 1, and a bent portion 2. A rotor 6 having an ear portion 5 having a hole 4 to be formed on its side portion, and a bent portion 2
Was provided with a stator (not shown) that rotatably couples the rotor 6 on the front end side.

[0003]

In the above-mentioned prior art, since the linear portion 1 of the actuating member 3 projects to the upper surface side of the rotor 6 by the thickness d thereof, the thickness of the switch as a whole increases, the occupied space increases, and the size is reduced. Was a major obstacle in this type of switch, which is essential.

[0004] Accordingly, the present invention solves the above problems,
The thickness of the switch is reduced to reduce the occupied space,
It is an object to provide a rotary switch that can achieve miniaturization.

[0005]

According to the present invention, an actuating member having a straight portion and a bent portion obtained by bending an end portion of the straight portion, and an ear portion having a hole for inserting the bent portion on a side portion. a rotor provided, and the case-shaped stator for rotatably coupling said rotor in distal direction side of the bent portion, the low
The outer circumference of the rotor and the inner circumference of the stator.
And a O-ring, in the ear, said by providing at least the stepped portion elaborate dropped about the thickness of the straight portion on the side of inserting the bent portion, wherein the actuating member is the straight line portion及
The protrusion on the upper surface of the rotor is
The center of the ear part in the vertical direction is
A rotary switch that substantially coincides with the vertical position of the O-ring is constructed.

[0006]

According to the present invention, in the ear portion provided on the side portion of the rotor, the stepped portion is provided on the side where the bent portion of the operating member is inserted, the stepped portion being at least about the thickness of the linear portion of the operating member. Both the linear portion and the bent portion of the actuating member have no protrusion on the upper surface side of the rotor, and the thickness of the switch can be reduced to occupy a smaller space and achieve miniaturization. In addition, the center position of the ear portion in the vertical direction is the O
Since it almost coincides with the vertical position of the ring,
When the member moves to rotate the rotor,
The vertical center position of the point of action applied from the material to the ear is
The rotor is almost aligned with the vertical position of the O-ring,
It becomes difficult for the twisting force to act on the O-ring from the
Rotation of the rotor with respect to the stator via the ring
It becomes smooth.

Embodiments of the present invention will be described with reference to FIGS.

1 to 4, an actuating member 3 having a straight portion 1 and a bent portion 2 in which an end portion of the straight portion 1 is bent, and an ear portion 5 having a hole 4 into which the bent portion 2 is inserted are shown. Rotor 6
And a stator 7 that rotatably couples the rotor 6 on the tip end side of the bent portion 2, and at the ear portion 5,
A door lock detection switch for an automobile is shown in which a step portion 8 which is at least about the thickness of the straight portion 1 is provided on the side where the bent portion 2 is inserted.

More specifically, the convex portion 9 provided on the outer periphery of the rotor 6 is inserted into and engaged with the annular concave portion 10 on the inner periphery of the case-shaped stator 7 by utilizing the flexure so that the rotor 6 is formed. It is illustrated as being rotatably coupled to the stator 7. A rotating contact piece 11 is fixed to the bottom surface of the rotor 6 by appropriate means, and the stator 7 is rotated as the rotor 6 rotates.
The fixed contact piece 12 fixed to the bottom surface is contacted and separated. O-ring 1
3 is fitted between the outer circumference of the rotor 6 and the inner circumference of the stator 7 to maintain waterproofness. Further, the fixed contact piece 12 has a terminal 14 extended to the outside of the stator 7. When the operating member 3 is moved by a door lock or the like (not shown), the rotor 6 rotates as shown in FIG. 3, and the rotating contact piece 11 comes in contact with and separates from the fixed contact piece 12.

According to the present embodiment, in the ear portion 5 provided on the side portion of the rotor 6, the step portion 8 which is at least about the thickness of the linear portion 1 is inserted on the side where the bending portion 2 of the operating member 3 is inserted. Since the actuating member 3 is provided, both the linear portion 1 and the bent portion 2 are provided.
Further, the protrusion on the upper surface side of the rotor 6 is eliminated, the thickness of the switch is reduced, the occupied space can be reduced, and the miniaturization can be achieved. The center position of the ear 5 in the vertical direction is O.
Since it almost coincides with the vertical position of the ring 13, it operates.
When the member 3 moves and the rotor 6 rotates, the operating member 3
The vertical center position of the point of action applied to the ear 5 from the
Is almost the same as the vertical position of the ring 13,
It becomes difficult for the twisting force to act on the O-ring 13,
Rotor for stator 7 with O-ring 13 interposed
The rotation of 6 becomes smooth.

[0011]

As described above, according to the present invention, in the rotary switch for inserting the bent portion of the operating member into the hole of the ear provided on the rotor side portion, the protrusion of the operating member on the upper surface side of the rotor can be eliminated. because, reduction of the space occupied by the thickness of the switch is reduced is Hakare, can achieve the miniaturization, it is
In addition, the rotation of the rotor relative to the stator is smooth
Has the effect of becoming .
