The guide groove 80 in this has a width that allows the ball 7 to be slightly fitted therein, and the corners of the ball 7 and the ball rolling surface 8 are chamfered so that the ball 7 can roll smoothly. To do. Further, the guide grooves 81 and 82 on both sides have a gently curved surface.

The slide switch of the present invention in this embodiment is constructed as described above, and its operation will be described below.

First, when the slider 3 is located at the neutral position N, the ball 7 is fitted in the guide groove 80 inside. At this time, since the two clip parts 51 of the slide contact 5 are in contact only with the contact part 400 of the common fixed contact 40, as shown in FIG. 13, the first electric circuit and the second electric circuit are in the open state. (OFF state).

Next, when the slider 3 is slid to the left in the drawing,
The ball 7 comes out of the inner guide groove 80 and rolls on the ball rolling surface 8. The protruding portion (the portion protruding from the end surface on the sliding direction side of the slider 3) at the left end of the spring 9 of the sound deadening member contacts the left inner end surface (inner wall surface) of the fixed body (case 2), and then The slider 3 contacts the left inner end surface of the fixed body (case 2) and stops. As a result, the spring 9 of the sound deadening member first comes into contact with the inner wall surface of the fixed body to prevent the slider 3 from coming into contact with the inner wall surface of the fixed body, and when the slider 3 comes into contact with the inner wall surface of the fixed body. The generated sound can be reduced. When the slider 3 is located at the first position I, the ball 7 fits in the guide groove 81 at the left end. At this time, the left clip portion 51 (51L) of the slide contact 5 contacts the contact portion 410 of the first fixed contact 41, and the right clip portion 51 (51R) contacts the contact portion 400 of the common fixed contact 40. As shown in FIG. 14, the first electric circuit is closed and the first electric bulb L1 is turned on.
If the slider 3 is slid to the right in this state,
The ball 7 comes out of the left guide groove 81 and rolls on the ball rolling surface 8. When the slider 3 reaches the neutral position N, the slider 3 is fitted into the guide groove 80 of the ball 7 and the slider 3 moves to the first position.
The position I is switched to the neutral position N, the first electric circuit which is in the closed state is opened, and the first light bulb L1 is turned off.

Further, when the slider 3 is slid to the right in the drawing, the ball 7 comes out of the inner guide groove 80 and the ball rolling surface 8
Roll over. The large-diameter portion 91 on the left side of the spring 9 abuts on the inner wall surface on the right side of the case 2, and then the slider 3 abuts on the inner end surface on the right side of the fixed body (case 2) and stops.
In the position II, the ball 7 fits into the right guide groove 82. At this time, the clip portion 51 (51R) on the right side of the slide contact 5 becomes the contact portion 420 of the second fixed contact 42,
Since the left clip portion 51 (51L) contacts the contact portion 400 of the common fixed contact 40, respectively, as shown in FIG. 15, the second electric circuit is closed and the second light bulb L2 is turned on.
If the slider 3 is slid to the left in this state,
The ball 7 comes out of the guide groove 82 on the right side and rolls on the ball rolling surface 8. When the slider 3 reaches the neutral position N, the ball 7 is fitted into the inner guide groove 80, the slider 3 is switched from the second position II to the neutral position N, and the second electric circuit is in the closed state. Opens and the second light bulb L2 goes out.

In this way, the slider 3 moves from the neutral position N to the first position I and the second position II while the ball 7 rolls on the ball rolling surface 8.
Moreover, since the first position I and the second position II are slid to the neutral position N for switching, a light load and smooth operation can be performed. In addition, the ball 7 is located at the position of the slider 3 where the predetermined electric circuit is switched between open and closed, the neutral position N, the first position.
Since the sliders 3 are fitted in the guide grooves 80, 81, 82 provided corresponding to the position I and the second position II, the slider 3 can be smoothly slid and a feeling of switching the slider 3 can be provided. it can.

Further, since the slider 3 and the operating rod 30 are manufactured separately, and the operating rod 30 is assembled to the slider 3, the manufacturing cost is higher than that in which the slider and the operating rod 30 are integrally formed. Can be reduced. Moreover, even if the slider 3 and the operating rod 30 are separately manufactured and assembled, the lower end portion 32 of the operating rod 30 is formed in a bifurcated shape, and the bifurcated lower end portion 32 is formed, as in the embodiment. The tip of each of these is bent to form a locking claw 33, and on the other hand, locking grooves 37 are provided at both ends of the lower surface of the through hole 36 of the slider 3, and the locking claw 33 is locked in this locking groove 37. , The operating movement of the operating rod 30 can be reliably transmitted to the slider movement of the slider 3,
It is possible to slide the slider 3 stably and reliably.

Although the ball 7 is used as the rolling element in the above-mentioned embodiment, it may be a roller.

Further, the slide switch of the present invention in this embodiment is composed of the housing grooves 300 and 301 provided in the slider 3 and the spring 9, so that the structure is simple.
Moreover, since the spring 9 is housed in the housing grooves 300 and 301 of the slider 3, the assembly is easy.

Further, the slide switch according to the present invention in this embodiment has a spring (coil spring) 9 as a sound deadening member.
Therefore, it is possible to easily set the load with which the spring 9 contacts the inner wall surface of the case 2. Therefore, it is most suitable for a slide switch in which the feeling of operation is important.
