The operation and operation of the push button / rotary type switch of the present invention in the push-on operation mode will be described with reference to FIG. FIG. 7A shows the mutual positional relationship among the lower casing 52, the lower magnetic disc 2, the upper magnetic disc 1, and the cylindrical outer shaft 4 in the casing 5 in the push-on operation mode. 51 is shown removed. FIG.7 (b) is a figure which shows the cross section of the vertical direction which passes along the center of a switch. FIG. 7 (c) is a view showing the cylindrical outer shaft 4 horizontally cut above the upper magnetic disk 1 and viewed from above. FIG. 7D is a view showing the cylindrical outer shaft 4 horizontally cut above the lower magnetic disk 2 and viewed from above. The polarities of the upper magnetic disk 1 and the lower magnetic disk 2 indicate the polarities of the surfaces facing each other, and the upper and lower magnetic disks 1 and 2 have the same polarity.

The lower magnetic disk 2 is rotated by rotating the selection operation knob 45 upward and rotating the arm 42 of the cylindrical outer shaft 4 into the circular recess 515 to rotate the lower magnetic disk 2 as shown in FIG. A push-on operating mode can be realized. That is, the square hole 41 formed at the center of the cylindrical outer shaft 4
The prismatic inner shaft 3 is fitted into the shaft, and the fixing portion 31 formed at the lower end of the prismatic inner shaft 3 is fitted and fixed to the circular hole 21 formed at the center of the lower magnetic disc 2. Therefore, the rotation operation of the selection operation knob 45 is transmitted to the lower magnetic disk 2 via the column outer shaft 4 and the prism inner shaft 3. In this case, in the upper magnetic disk 1, the pair of semi-circular recesses 13 has the upper casing 51.
Since they are fitted to the pair of guide ridges 514 having a semicircular cross section, they do not rotate. In this way, the lower magnetic disc 2 is rotated, and the concave groove 22 of the lower magnetic disc 2 is inserted into the lower casing 52.
The protrusions 521 are made to escape from each other and the two are positioned orthogonally to each other. By rotating the lower magnetic disk 2 relative to the upper magnetic disk 1, the repulsive force acting between them increases. This positioning is performed by the engaging projection 4 formed at the lower end of the arm 42 to which the elasticity of the columnar outer shaft 4 is given.
This can be easily carried out by elastically engaging and engaging 3 with the locking hole 12 formed in the upper surface of the upper magnetic disk 1 which receives the upward repulsive force. In this state, the polarities of the upper magnetic disk 1 and the lower magnetic disk 2 are the same as each other in the upper and lower directions, so that both magnetic disks repel each other and are separated from each other. The upper magnetic disk 1 is pressed against the inner upper surface of the upper casing 51 by the upward repulsive force caused by the lower magnetic disk 2, and the lower magnetic disk 2 is caused by the upper magnetic disk 1. The lower surface thereof is pressed against the raised portion 521 of the lower casing 52 by the downward repulsive force.

In the push-on operation mode, in the push-button / rotary type switch of the present invention, the polarities of the upper magnetic disk 1 and the lower magnetic disk 2 are the same as each other, as described above, and both magnetic disks are the same. Are repelled from each other and are spaced apart, and are normally off. Therefore, the electric circuit formed through the upper current collecting brush 516, the upper magnetic disk 1, the lower magnetic disk 2, and the lower current collecting brush 524 is the same as the upper magnetic disk 1 and the lower magnetic disk 2. Since they are separated from each other, they are shut off. Here, when the selection operation knob 45 is pressed, the upper magnetic disc 1 is driven downward via the arm 42 at the lower end of the cylindrical outer shaft 4 to come into contact with the lower magnetic disc 2, and the switch is turned on. It becomes a state. When the pressing operation of the selection operation knob 45 is released, the magnetic discs are separated by the repulsive force between them and are returned to the off state.

The operation and operation of the push button / rotary switch of the present invention in the push-off operation mode will be described with reference to FIG. FIG. 8 (a)
The lower casing 52, the lower magnetic disc 2, the upper magnetic disc 1, and the cylindrical outer shaft 4 in the casing 5 in the push-off operation mode are shown in a relative positional relationship with each other, and the upper casing 51 is shown as removed. ing. FIG. 8B is a diagram showing a vertical cross section passing through the center of the switch. FIG.
FIG. 3C is a diagram showing a state where the cylindrical outer shaft 4 is horizontally cut above the upper magnetic disk 1 and viewed from above. FIG.
(D) is a diagram showing a state where the outer cylinder 4 is horizontally cut above the lower magnetic disc 2 and viewed from above. The polarities of the upper magnetic disk 1 and the lower magnetic disk 2 indicate the polarities of the surfaces facing each other, and the upper and lower magnetic disks 1 and 2 indicate that they are in opposite polarities.

From the push-on operation mode shown in FIG. 7, the lower magnetic disc 2 can be rotated by rotating the selection operation knob 45 to realize the push-off operation mode shown in FIG. That is, the prismatic inner shaft 3 is fitted in the rectangular hole 41 formed at the center of the cylindrical outer shaft 4, and the fixing portion 31 formed at the lower end of the prismatic inner shaft 3 has the lower magnetic disc 2 formed therein.
Since it is fitted and fixed in the circular hole 21 formed in the central portion of the, the rotation operation of the selection operation knob 45 is performed through the column outer shaft 4 and the prism inner shaft 3 to the lower side as in the case of FIG. Magnetic disk 2
To communicate. In this case, the upper magnetic disk 1 does not rotate because the pair of semi-circular recesses 13 are fitted into the pair of semi-circular guide ridges 514 of the upper casing 51. In this way, the lower magnetic disk 2 is rotated, the concave groove 22 of the lower magnetic disk 2 is aligned with the raised portion 521 of the lower casing 52, and both are positioned in a fitted state. By rotating the lower magnetic disk 2 relative to the upper magnetic disk 1, the repulsive force acting between the two is decreased and the attractive force is increased. This positioning is performed by the selection operation knob 4
By rotating 5 the arm 42 of the cylindrical outer shaft 4 is rotated, and the engaging projection 43 at the lower end of the cylinder is elastically disengaged from the locking hole 12 of the upper magnetic disk 1 and further rotated. This can be easily performed by continuing the operation and aligning the arm portion 42 with the oblong slot 11 of the upper magnetic disk 1.
Here, as described above, since the length of the square hole 41 of the columnar outer shaft 4 is formed shorter than the length of the prismatic inner shaft 3 which is fitted and slid into the square hole 41, the upper end of the prismatic inner shaft 3 is formed. 41 is a square hole
Abut on the deepest top of the. In this state, the polarities of the upper magnetic disk 1 and the lower magnetic disk 2 are opposite to each other, so that an attractive force acts between the magnetic disks to couple them. The upper magnetic disc 1 and the lower magnetic disc 2 which are coupled and integrated with each other engage the ring-shaped stopper 522 formed at the inner edge of the opening of the lower casing 52 at the peripheral portion of the upper magnetic disc 1. And be supported.

In the push-off operation mode, in the push button / rotary switch of the present invention, the polarities of the upper magnetic disk 1 and the lower magnetic disk 2 are opposite to each other as described above, and both magnetic disks are Suction-coupled and normally on. Therefore, the upper current collecting brush 51
The electric circuit formed via 6, the upper magnetic disk 1, the lower magnetic disk 2, and the lower current collecting brush 524 is in a conductive state.
Here, when the selection operation knob 45 is pressed, the lower magnetic disc 2 is driven downward through the upper end of the square hole 41 of the columnar outer shaft 4 and the prismatic inner shaft 3 that fits and slides in the square hole 41. The upper magnetic disk 1 is separated from the upper magnetic disk 1, and the switch is turned off. When the pressing operation of the selection operation knob 45 is released, both magnetic disks are connected by the mutual attractive force and are returned to the ON state.

Finally, the rotary operation mode will be described. As described above, by rotating the selection operation knob 45 from the state of the push-on operation mode of FIG. 7, the lower magnetic disk 2 can be rotated to realize the push-off operation mode of FIG. . The switch is in the off state in the push-on operation mode, and the switch is in the on state in the push-off operation mode. The switch is finally switched from the off state of the push-on operation mode to the on state of the push-off operation mode by rotating the selection operation knob 45, that is, by rotating the selection operation knob 45. By rotating the selection operation knob 45, conversely, the push-off operation mode of FIG. 8 can be switched to the push-on operation mode of FIG. 7, and the switch can be switched from the on-state to the off-state.

As described above, in the push button / rotary type switch of the present invention, the permanent magnet is used as a contact, and the attractive repulsive force of the permanent magnet is used as a return spring mechanism to provide a selective operation unit. According to this selection operation, the switch is selected as a push-on / off operation type switch or a rotary on / off opening / closing operation type switch.

As described above, in the push button / rotary type switch of the present invention, it is not necessary to switch the wiring connection between the switch and the circuit to which the switch is connected in order to convert the switching logic. It can be easily implemented without. In addition, the conversion of the switching logic does not require an inverter or a special conversion circuit in addition to the switch body, and the switching logic conversion can be performed by the switch alone without the need for arithmetic processing by a computer.
