At this time, the slider 1 is the push switch 3
The movable switch 3a is pushed to turn on the push switch 3. Further, since the movable protrusion 4a of the push switch 4 is released, the push switch 4 is off. Therefore, the conduction states of the push switches 3 and 4 are as strongly shown in FIG.

Next, the slider 1 is moved to the inside position. Also at this time, the slider 1 is positioned by the above method. At this position, since the movable protrusions 3a and 4a are both released, the conduction states of the push switches 3 and 4 are as shown in FIG.

Similarly, when the slider 1 is set to the weak position, the slider 1 pushes the movable projection 4a, and the push switches 3 and 4 are brought into the conducting state as shown by the weak line in FIG.

As described above, in this embodiment, by disposing the two push switches 3 and 4 as shown in FIG. 1, it is possible to obtain three different conduction states depending on the position of the slider 1.

Since the protrusions push in the movable protrusions of the push switch 5, the conduction states of the push switches 3 to 5 are as shown in 1 of FIG. Similarly, the positions 1 to 7 of the slider 1 are brought into a conducting state as shown in FIG.

As described above, in the present embodiment, by combining the three push switches 3 to 5 and the different protruding rods 11 to 13 as shown in FIG. 6, different conduction states as shown in FIG. 7 can be obtained. In particular, in this embodiment, the protruding rod 11 is a binary number of 3 bits with the push switch 3 as the most significant bit and the push switch 5 as the least significant bit.
It is characterized by determining the projection pattern of ~ 13,
The number of binary bits can also be increased or decreased by increasing or decreasing the push switch and the protruding bar.
