The part of the terminal fitting 4c attached to the other side of the block body 3 that protrudes inward from the block body 3 protrudes further inward than the other terminal fittings 4a and 4b, is bent toward the terminal fitting 4b, and the end portion A fixed contact 14 is provided at a position opposite to the movable contact 11. A barrier wall 17 protruding from the inner surface of the case 2 is located between the pair of fixed contacts 14 .

In this way, each of the movable contacts 11 is arranged between the fixed contacts 13 and 14, and in the normal neutral position, as shown in FIG. It has become.

The movable lever 6 is rotatably attached to a boss 16 that is provided at the lower part of each of the movable contact members 5 and protrudes upward from the inner surface of the case 2 at a portion where the other side is located further outward than the terminal fitting 4c. It is supported on a shaft. An actuating part 18 having a cylindrical actuating engaging part 20 protrudingly formed on the upper surface is provided on the upper part of one side of the movable lever 6, and this actuating part 18 is located just between the respective movable contact members 5. It is located so that it is sandwiched between the two.

As shown in FIG. 3, the slide member 7 is
It has a plate shape, and each of the side parts located in the longitudinal direction of the slide base 19 is placed on a slide step 21 formed on the inner upper edge of both block bodies 3, and is provided on the above-mentioned contact mechanism. There is. The slide member 7 is provided with a tilt operation hole 22 on one side, and an operation button 2 on the top surface of the other side.

A pair of slits 26 are formed along the longitudinal edges on both sides of the slide member 7, and a semicircular engagement protrusion 28 is formed at the center of the outer portion 27 of the slit 26. Each is formed to protrude outward. The above-mentioned slit 26 is provided so that its outer portion 27 can be slightly deformed inwardly and outwardly, and accordingly, the engaging convex portion 28 provided in that portion is also configured to be able to be displaced inwardly and outwardly. . Then, the slide member 7

This prevents contact failures caused by dust getting inside the switch. When moving together with the slide member 7, its upper surface slides on the lower surface of the cover 8, but since it is made of a slippery material such as nylon or Teflon, the movement is smooth.

Next, the operation of the switch 1 will be explained.

The position shown in FIG. 1 is a neutral position in which the operating button 23 is not operated, and in this state, the actuating portion 18 of the movable lever 6 is just connected to both movable contact members 5.
The two movable contact members 5 are located between the movable contact members 5 and the movable contact members 5 are not displaced, so that each of the movable contacts 11 is in contact with the inner fixed contact 14 due to the biasing force of the leaf spring 10. In this state, when the switch 1 is used, for example, to supply power to a load, the movable contact 11 is separated from the fixed contact 13, so power is not supplied. Further, in this neutral position, the engagement protrusion 28 is engaged with the engagement recess 30, so that the slide member 7 is stably positioned.

In FIG. 1, when the slide member 7 is moved, for example, to the left by operating the operation button 23, the engagement actuation hole located inside the inclination actuation hole 22 moves. The part 20 is displaced downward, and as a result, the actuating part 18 provided in the engagement actuating part 20 is displaced together, so that its lower end reversely displaces the lower movable contact member 5 downward. The movable contact 11 provided on the movable contact member 5 is spaced apart from the fixed contact 14 and comes into contact with the fixed contact 13.

Due to the movement of the slide member 7, the engagement protrusion 28 is disengaged from the engagement recess 30, and the engagement protrusion 28 comes into elastic contact with the rising surface 32 of the slide step 21.
Also in this case, the slide member 7 is prevented from shaking.

[0022] Then, with the return operation by the operation button 23, the movable contact member 5 is reversely displaced, the movable contact 11 is separated from the fixed contact 13 and comes into contact with the fixed contact 14, and the engagement protrusion 28 is moved into the engagement recess. 32.

When the slide member 7 is moved rightward from the neutral position, the upper movable contact member 5 is displaced with the movement of the slide member 7, and the upper contact mechanism performs the opening/closing operation in the same manner as described above. be exposed.

As described above, the operating direction of the slide member 7 is displaced in the orthogonal direction by the rotation of the movable lever 6, and the movable contact member 5 is displaced in the same direction as the direction of displacement. The opening and closing operations of the contacts are performed.

[0025]

[Effects of the Invention] According to the present invention, the displacement of the movable contact member is perpendicular to the operating direction of the slide member, and
Since one end of each terminal fitting protrudes to the outer surface of the switch in the direction of displacement of the movable contact member, the vertical dimension of the entire switch is reduced, thereby providing a thin slide operation switch.

Furthermore, since each terminal fitting does not protrude from the bottom surface of the switch but from the side surface, it is possible to position it on the board, and the slide can be automatically mounted on the board. An operation switch is obtained.
