As disclosed in Japanese Patent No. 12273, the mechanism is arranged in the center of the device. Therefore, if an attempt is made to adopt this type of alternate mechanism in an illuminated push button switch, a configuration in which the push button section, illumination section, alternate mechanism, and switch mechanism are stacked in sequence is adopted as disclosed in Publication of Utility Model Publication No. 53-26627. Unavoidably, this not only increases the height and size of the entire device, but also makes the mechanism of the entire device extremely complex.

示灯およびリード金具１２は不要である。 This invention will be explained in detail below with reference to an embodiment shown in the drawings. Reference numeral 1 indicates a main body case in which the upper side is formed into a cylindrical body and the lower side is formed into a box body, and 2 indicates a mounting portion 2d on a protrusion 1a that protrudes downward within the box body of the main body case 1.
3 is an operating rod supported by a spring 4 in the cylinder of the main body case 1, and a push button 5 is screwed into the upper end screw portion. At the same time, the operating rod 6, the rotating rod 7, the push plate 8, and the press plate 9 are fitted in order from below, and the lower end of the press plate 9 is supported upward by a support spring (not shown) on the contact block 10. The operating rod 6, the rotating rod 7, and the pressing plate 9 are in contact with a movable contact support 11, and are constantly subjected to an upward pressing force by the support spring of the support 11. The cylindrical pipe 2 has protrusions 2a on its inner periphery, grooves 2b are formed at equal intervals, and one end of the protrusions 2a has a sawtooth shape with a step 2c formed approximately in the center. Note that the axial length of this protruding portion 2a is the same as that of the push button 5.
Determined by the pressing stroke. Four of the grooves 2b are passed through in the vertical direction, and protrusions 6a formed at four locations on the circumferential surface of the operating rod 6 are fitted into these grooves 2b. Move up and down within 2b. At the lower end of the projection 6a of the operating rod 6 and at the lower end on the circumference of the operating rod 6, inclined portions 6b in the same direction are formed at equal intervals, and projecting pieces 7a are provided at equal intervals on the rotating rod 7. It is in pressure contact with an inclined portion 7b formed on the upper surface of the. Further, the operating rod 6 has tongues 6c, 6c which are opposed and protruded from the inner periphery toward the center thereof, and are fitted into window holes 3a, 3a provided oppositely on the lower side of the operating rod 3. Reference numeral 9 indicates the upper end of the push plate 8 by inserting the push plate 8 into the cylindrical body 9a and pushing the guide protrusions 8a, 8a protruding inside the push plate 8 into the notches 9c, 9c formed on the outside of the flange 9b. The lower surface of the flange 8b formed on the inside is the flange 9.
This is a pressing plate that abuts and locks with the upper surface of b, and the protrusions 9d, 9d provided oppositely on the inner wall of the cylinder body 9a of the pressing plate 9 are fitted into the window holes 3a, 3a of the operating rod 3. The push plate 8 and the push plate 9 are integrally attached to the operating rod 3. In the illustrated example, the press plate 8 and the press plate 9 are
Although they were formed separately, they may be formed integrally. Reference numeral 12 denotes an indicator light and a lead metal fitting that are held through a hollow portion G formed in the center of the operating rod 3. The indicator light and lead metal fitting 12 are not required when configuring a simple push button switch.

たは動作された接点は復帰しない。 Next, to explain the operation, when the push button 5 is pressed in FIG. 1, the operating rod 3 is pushed down against the spring 4, and the movable contact support 11 is is pressed down to switch or operate the contact. At this time, the lower end inclined portion 6b of the operating rod 6 pushed down by the operating rod 3 pushes the upper end inclined portion 7b of the protruding piece 7a of the rotating rod 7 fitted into the groove 2b, as shown in FIG. Lower it. However, since the rotating rod 7 is subjected to an upward pressing force by the support spring of the support body 11, when it descends to the lower end of the protruding portion 2a, its inclined portion 7b is no longer in pressure contact with the inclined portion 6b, and the rotating rod 7 is pushed upwardly. It rotates along the serrated edge of the lower end of the portion 2a to the position shown by the chain line (i.e., the stepped portion 2c
It slides to the position ( ) and stops. When the hand is released at this position, the protrusion 6a of the operating rod 6 can return upward in the groove 2b together with the operating rod 3 supported by the spring 4, but the protruding piece 7a of the rotating rod 7 As a result, the movable contact support 11 is locked and the switched or operated contact does not return.

された接点は復帰する。 Next, when the push button 5 is pressed again, the protruding piece 7a of the rotating rod 7, which descends by being pressed against the lower end inclined portion 6b of the operating rod 6, rotates again along the lower end serrated side when it comes off the stepped portion 2c. When the next groove 2b appears and the hand is released, the support 1 moves along this groove 2b.
The support body 11, which has been returned upward together with the operating rod 3 by the support spring 1 and released from the pressure of the press plate 9, is returned by the support spring, and the switched or operated contacts are returned to their original positions.

できるなど種々の実用的効果を奏する。 According to this idea, the center of the alternate mechanism,
In other words, since a hollow part G is formed in the center of the operating rod 3, when configuring an illuminated push button switch, the height of the device can be reduced by inserting and holding the indicator light and lead fitting 12 into this hollow part G. This makes it possible to significantly reduce the size compared to conventional ones. If the switch is simply used as a push button switch, the indicator light and lead fitting 12 may be omitted. Further, according to this invention, the rotating rod 7 used in the alternate mechanism is provided with a plurality of protruding pieces 7a on the circumferential surface of a large-diameter annular body.
Since the pressing force from the supporting spring is dispersed by a large number of protruding pieces 7a, the pressing force applied to each protruding piece can be made extremely small. It is possible to change the material from the expensive sintered metal material to an inexpensive resin material, resulting in various practical effects such as reducing material costs.
