DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a lever type push switch according to the present invention will be described below with reference to the drawings. In FIG. 1 to FIG. 3, a reference numeral 1 denotes an operation lever provided in the case 2 so as to be able to be pushed and rotated freely, and a shaft portion 3 formed substantially at the center of the operation lever 1 is The shaft 3 is provided so as to be able to be pushed and rotated freely into a long hole 4 formed in the case 2.
The cover 5 is provided so as to be inserted into and rotatable in, for example, a long hole 5a of a metal cover 5 provided therein. Note that the shaft portion 3 and the long holes 4 and 5a constitute turning / pressing means 6 for pushing and rotating the operation lever 1 so as to be freely rotatable. The same operation can be obtained when the elongated hole 4 is formed in the operation lever 1 and the shaft 3 is formed in the case 2.

A sliding rod 8 is provided in the gap 1a of the operation lever 1 via a spring 7, and the spring 7
The shaft portion 3 of the operating lever 1 is
5a is always urged to the upper end side. The distal end of the sliding rod 8 is in sliding contact with a positioning concave body 9 provided separately on a moderating base 10 formed in the case 2 and having a substantially V-shaped overall shape. The operation lever 1 is locked when it is positioned in the concave portion 9a of the concave body 9.

A plurality of fixed terminals 1 are provided at the end of the case 2.
A terminal block 20 having 8a, 18b, 18c, and 18d is provided, and one fixed terminal 18b located inside is formed in an L-shape, and the fixed terminal 18b is connected to the adjacent fixed terminal 18c. It is bent to cover. A pair of resilient claws 30 are formed at the tip of the operation lever 1a, and each of the claws 30 is provided with a movable contact piece 12 having a U-shape as a whole. When 1 is pressed, the movable contact piece 12 moves forward, and the fixed terminals 18b and 18c are connected and turned on. Note that a stop method other than the fitting type is also possible. The shaft 3 engaged with the long hole 5a of the cover 5 is provided with a ring 20 having a T-shaped cross section made of metal or the like, and the shaft 3 made of resin is formed into the long hole 5a made of metal. It is configured so that it does not directly contact with. A moderation spring plate 21 having a bent contact portion 21a is detachably provided on the surface of the cover 5, and the contact portion 21a
Is engaged with the flange portion 20a of the ring 20, so that when the operation lever 1 is pushed in, a temporary moderation of the operation lever 1 can be obtained. The moderation spring plate 21 may not be used depending on the user's specifications.

Next, the operation will be described. First, the state shown in FIG. 1 is a free position where the operating lever 1 is not pushed in and not rotated. When the operating lever 1 is rotated rightward from this position, the state shown in FIG. Are fixed terminals 18
b, 18d to be turned on by contact, and switching is performed. Also,
When the operating lever 1 is pushed in from the position shown in FIG. 1, as shown in FIGS.
8c is turned on, and switching by push is performed. Therefore, it can be turned on and off by pushing and rotating the operation lever 1 respectively.

Next, although the operation lever 1 is not provided with a cap, as shown in FIG.
0 can also be provided. In addition, the aforementioned ring 20
As shown in FIG. 2, the cross-sectional shape is substantially T-shaped, but the shape may be cylindrical or cup-shaped. The shape of each part described above is an example, and even if the shape is slightly changed, the same operation can be obtained. As shown in FIG. 8, six fixed terminals 18a to 18f are provided.
In this case, as shown in FIG. 9, seven fixed terminals 18a to 18
g, the movable contact piece 12 may be formed in a three-pronged shape, and the switching can be performed twice in the same direction from the free position in FIG. 9 as shown in FIGS. 11 and 12.

[0011]

The lever-type push switch according to the present invention is configured as described above, so that the following effects can be obtained. In other words, since the operation lever is pushed / rotated with respect to the case and the cover using the pivot / push means by the shaft portion and the long hole, the push / rotation can be performed with small size and high precision, and the sliding can be performed. The combination of the rod and the recess enables automatic return and lock when the operation lever is rotated, and also allows automatic return when the push-in operation is selectively performed.
