[Prior Art] In this type of slide operation switch, when the operating section is operated, the slide member slides on the step on the switch body side, and as this movement moves, one end of the slide member interlocks the switch mechanism. This turns the switch mechanism ON and OFF.

[0003] In order to prevent rattling, the slide member is sometimes positioned at a non-operating position, which is the neutral position of the switch. This is done by being engaged with a recessed engagement part formed on the side wall of the stepped part on the side of the switch body, and this engagement has to be released by operating the slide member, so it needs to be done elastically. there were.

[0004] In order to obtain the above-mentioned elastic engagement, a conventional structure is such that a spring is loaded in the engagement portion of the slide member.

[0005]

[Problem to be Solved by the Invention] However, in recent years, with the miniaturization of equipment and equipment, it is necessary for this type of switch to be configured extremely compactly. Therefore, it is necessary to incorporate a spring into the slide member as described above. This method is difficult, time-consuming, and has the disadvantage of increasing costs.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a slide operation switch in which positioning by engagement of a slide member is performed with a simple structure.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention is configured such that a switch mechanism provided inside a switch body is operated by a slide member consisting of an operating section and a slide base. In this slide operation switch, a pair of slits are formed along the inside of both sides of the slide side of the slide base so that the portion located on the outside can be deformed inwardly and outwardly, and a pair of slits are formed on the outside thereof. An engaging convex portion protruding outward is formed in each of the positions thereof, and an engaging recess with which the engaging convex portion engages is formed in a portion of the switch body on which the slide member slides. The structure is as follows.

[0008]

[Operation] According to the above structure, since the engaging convex portion is provided on the outer side of the slit which can be displaced inwardly and outwardly due to the existence of the slit, the engaging convex portion can also be displaced and engage the switch body. Engagement with the recess is performed, and disengagement is also performed in accordance with the displacement of the engagement protrusion.

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.
