Since the movable lever 5 is moved along the sliding guide portion 1c of the storage portion 1a in the pressing direction of the operating lever 5, that is, the downward direction as shown, the movable side contact 4f is moved to the movement of the operating lever 5. It moves along the downward direction shown and is connected with the fixed side contact 3.

At this time, the movable side contact 4f moves the center image of the pair of contact plates 3a and 3a of the fixed side contact 3 in a straight line so that no vibration in the horizontal direction occurs. In addition, since the sliding surface portions 5e and 5f are restricted by the sliding guide portion 1f, the operation lever 5 can prevent the occurrence of rattling in the lateral direction even when pressing and tilting conduction operations.

By releasing the pressing to the operating lever 5 in the states of Figs. 4, 6 and 8, the operating lever 5 is returned to the initial state shown in Fig. 1 by the elastic force of the coil spring 4, respectively. .

9 to 12 show a second embodiment of the present invention, in which FIG. 9 is a plan view of a state where the cover of the detection switch is removed, and FIGS. 10 to 12 show an operation state when operating the operation lever of the detection switch. 10 is an explanatory view showing a state in which the operation lever is inclined in the left direction, FIG. 11 is an explanatory view showing a state in which the operating lever is inclined in the right direction, and FIG. 12 is a view in which the operating lever is pressed in the pushing direction. It is explanatory drawing which shows the state.

In addition, about the same component demonstrated in FIGS. 1-8, the same code | symbol is attached | subjected and the description is abbreviate | omitted. In addition, the fixed side contact 2 and the connection terminals 2b and 3b are similarly omitted.

In this case, the difference from the first embodiment is that the structure of the sliding guide portion 1c provided on the housing portion 1a of the housing 1 and the sliding surface portions 5e, 5f provided on the operating lever 5 are slightly different. to be. That is, the operating lever 15 which is the second embodiment of the present invention is the same in that it has a pair of rotary motion shaft portions 15c and 15d at both sides, but is different in that the sliding surface portion 15e has a different configuration. .

In this case, the operation lever 15 is formed in a triangular shape by an insulating material such as synthetic resin, and a pair of inclined surfaces 15a and 15a having different directions are formed on the front end side thereof. A locking hole 15b is formed in the center of the operating lever 15 to hold the bent portion 4e of the arm portion 4c. A tip end portion of the bent portion 4e caught by the locking hole 15b is movable. It becomes the contact 4f, and this movable side contact 4f is brought into contact with the fixed side contact 3 in accordance with the movement of the operating lever 15.

In addition, on both sides of the operating lever 15, rotational shaft portions 15c and 15d are formed to contact the upper surface of the housing portion 1a of the housing 1 so that rotational movement is possible. By installing the rotary shafts 15c and 15d on both sides of the operating lever 15, the operating lever 15 can be inclined in both left and right directions, and the operating lever 15 is inclined in one direction. When the fall operation is performed, the operation lever 15 is first rotated with the rotational motion shaft portion 15c (or 15d) on the side opposite to the inclined conduction direction as a point.

In addition, a circular protrusion is formed at the center of the operating lever 15 so as to be connected to the locking hole 15b and centered on the locking hole 15b. A sliding surface 15e is provided on the outer peripheral side of the protrusion. Formed. Moreover, this sliding surface part 15e is formed in concentric shape centering on the said locking hole 15b.

Then, in the housing portion 1a of the housing 1, the sliding surface portions 15e of the operating lever 15 are fitted on both sides during the pressing operation of the operating lever 15 and the inclined conduction operation in the left and right directions. In the state, the sliding guide part 1d which consists of parallel vertical walls which guides the movement is formed. This sliding guide part 1d is formed near the center of the accommodating part 1a, and when the operation lever 15 is moved, the operation lever 15 does not contact the side wall of the accommodating part 1a. It is supposed to regulate the movement.

Next, operations of the detection switch as the second embodiment of the present invention described above will be described with reference to FIGS.

First, in the initial state (Fig. 9), the inclined conduction is operated to the left by the mechanism not shown. At this time, since the operating lever 15 rotates counterclockwise with the rotational shaft portion 15d on the right as a point, the movable side contact 4f is fixed in accordance with the rotational movement of the operating lever 15. It is connected with a side contact (not shown). Further, when the operation lever 15 is tilted to the last in the left direction, the operation lever 15 is moved downward while the sliding surface portion 15e rotates along the sliding guide portion 1d. , The movable side contact 4f is also moved downward (Fig. 10).

At this time, as the movement lever 15 moves in the pushing direction, the right rotational movement shaft portion 5d, which becomes the rotational movement point, moves away from the locking portion of the accommodating portion 1a and moves to the left side as shown. In addition, a pair of the arm portions 4b and 4c are hung on the fixed terminal 2 and the operation lever 15 and the coil portion 4a is free of the housing portion 1a of the housing 1. Since the coil spring 4 is bent in the direction, the bends 4d and 4e of the arm portions 4b and 4c are bent in a direction connecting the bent portions 4d and 4e.

Further, the movable side contact 4f is hung by the engaging hole 15b formed at the center of the concentric circle which forms the sliding surface portion 15e of the operating lever 15, and inclined conduction operation of the operating lever 15 is performed. Since there is no horizontal vibration because the linear movement in the downward direction as shown in the can be obtained the same effect as the first embodiment.

Fig. 11 shows a case in which the operating lever 15 is inclined in the right direction. At this time, the operating lever 15 rotates in the clockwise direction with the rotation axis 15c on the left as a point. The movable side contact 4f is connected with a fixed side contact (not shown) in accordance with the rotational movement of the operating lever 15.

Also at this time, the movable side contact 4f moves in a straight line downward in accordance with the inclined conduction operation of the operating lever 15, so there is no vibration in the horizontal direction.

Fig. 12 shows a case in which the operating lever 15 is pressed vertically downward, wherein the operating lever 15 has a sliding surface portion 15e for sliding of the housing portion 1a of the housing 1. Since the movable lever 15 moves along the guide portion 1d in the pressing direction of the operating lever 15, that is, the downward direction shown, the movable-side contact 4f moves downward and is fixed in accordance with the movement of the operating lever 15. It is connected with a side contact (not shown).

At this time, the movable side contact 4f is moved in a straight line on the center of the pair of contact plates of the fixed side contact (not shown), so that no vibration in the horizontal direction occurs.

By releasing the pressing on the operating lever 15 in the states of FIGS. 10, 11, and 12, respectively, the operating lever 15 returns to the initial state shown in FIG. 9 by the elastic force of the coil spring 4. .

Incidentally, in the above embodiment, the sliding surface portions 5e, 5f (or 15e) formed on the operating lever 5 (or 15) are formed in an arcuate shape having the same diameter, that is, the same circumferential surface, but not limited thereto. What is necessary is just to form the concentric shape centering on the said latching hole 5b (or 15b), and the diameter of the sliding surface part 5e, 5f (or 15e) formed in the left and right sides of the said operation lever 5 (or 15) may be You may form differently, respectively. In this case, what is necessary is just to form the said guide part 1c (or 1d) according to the diameter of the said sliding surface part 5e, 5f (or 15e). In this case as well, the same effects as in the above embodiment can be obtained.

As described above, the detection switch of the present invention is provided with an operating lever which is installed in the accommodating portion with a part protruding and at the same time the arm of the coil spring is caught and moves the movable side contact to the fixed side contact side against the elastic force of the coil spring. A sliding guide portion is formed in one housing to contact the operating lever and guide the movement of the operating lever during pressing operation and inclined conduction in the left and right directions, and an arc-shaped sliding slide with the sliding guide portion on the operating lever. Since the surface portion is formed, even when the operation lever is pressed and inclined conduction operation, the operation lever is to be in contact with the sliding guide portion of the circular arc surface of the sliding surface portion at all times to prevent the occurrence of rattling in the horizontal direction.

Also, on both sides of the operating lever, a rotating shaft is formed on the upper surface of the housing of the housing so as to be rotatable. When the operating lever is inclined in one direction, the rotating shaft on the side opposite to the inclined conduction is set as a point. At the same time as the operation lever rotates, the sliding surface portion is formed to slide in the pressing direction along the sliding guide portion, and the rotational movement shaft portion which becomes the rotational movement point according to the movement in the pressing direction of the operation lever moves away from the locking portion of the accommodating portion. Since the center position of the operation lever does not move from side to side, the trajectory of the linear lever can always be tracked and the movable contact can also be moved linearly, thereby preventing vibration in the horizontal direction.

In addition, since the engaging portion to which the arm portion of the coil spring formed on the operating lever is formed is formed at the center of the concentric circle passing through the arc surface of the sliding surface of the operating lever, the movable side contact is fixed-side contact according to the inclined conduction operation of the operating lever. The center phase of the pair of contact plates is moved linearly, and only one side of the contact plate is not largely bent (one-sided contact), thereby preventing damage to the contact plate due to the increase of the spring stress. The shape can be simplified.

In addition, the sliding surface portion is formed concentrically so as to protrude outward from the opposite side portion of the operation lever, while the sliding guide portion is formed of a pair of parallel sidewall portions opposed to the inner surface portion of the housing portion of the housing, thereby simplifying the structure. The switch can be miniaturized.

Since the operation lever is formed with a plurality of inclined surfaces having different directions on the protruding portion of the housing, operation control in all directions, such as inclined conduction operation in both the left and right directions and pressing operation in the pressing direction, is possible with one operation lever. .
