チとして実開昭58−107528号のものがある。B. Prior art Utility Model Application No. 58-107528 is a push-button switch that reciprocates an operator and thereby causes a slider containing a movable contact piece to reciprocate in a direction perpendicular to the operator to switch and connect a plurality of fixed terminals. There is something like that.

An inverted dog-shaped groove is formed in the lower part of the slider to allow insertion of the protrusion of the slider and to guide the engagement protrusion.

ない欠点がある。 Further, in Japanese Utility Model Application Publication No. 18626/1986, a sloped part is formed at the tip of the lever member of the pushbutton, and this sloped part is brought into contact with the sphere housed in the U-shaped seating part of the movable case. It is composed of
There are five contact surfaces between the U-shaped seating part and the sphere, and even if the ball is ejected outward by the inclined part at the tip of the lever, the ball hardly rolls and the frictional resistance is large, making it difficult to move the case. It has the disadvantage that it cannot be operated easily.

ることが不可能である。C. Problems to be Solved by the Present Invention In the conventional push-button switch described above, the contact between the operator and the slider is made within an inverted dog-shaped groove within the operator, and the slider has a convex portion provided at its upper part. The upper part of the handle engages with the groove of the operator and becomes the point of action that drives the slider, but because this is located at an upper position that is farther away from the lower position that accommodates the movable contact piece, the slider cannot necessarily be driven stably. Moreover, since the protrusion that engages with the groove is in the shape of a round bar that is provided integrally with the convex part, sliding friction occurs due to two-line contact in the longitudinal axis direction of the diameter of the round bar, and the frictional resistance is also large to some extent and the operation feeling is not necessarily good. The problem is that there is no. Further, even if an attempt was made to change the engaging protrusion of the slider of Japanese Utility Model Application No. 58-107528 to a ball, it would be impossible to use a ball because the knob lacks a structure for accommodating and guiding the ball.

Function The push button switch of the present invention has a slider formed with a groove into which the operation plate of the operator is inserted, and a dogleg-shaped hole formed in the groove to guide a ball placed in the through hole of the operation plate. However, by combining this slider, operator, and ball, a mechanism for changing the movement direction of the operator and slider, which is performed by the engagement of the ball and the dogleg-shaped hole, is provided inside the slider, which is different from the conventional method. The movement of the slider is stable because it is not provided in a lopsided position such as at the upper part away from the main body of the slider.

とができる。 In addition, a dogleg-shaped hole is formed in the inner wall surface of the groove of the slider that accommodates the operating center so as to reciprocate, so that the front and rear surfaces of the ball fitted into the through hole of the operating element fit into it. When reciprocating, the upper and lower surfaces and left and right surfaces of the ball are guided by the through hole in the operator and the dogleg-shaped hole in the slider to reduce friction, making the push-down movement of the operator and the left and right movement of the slider smooth and light. I can make you do it.

されている。 The slider 7 is provided with protrusions 13 and 14 for sliding on the top and bottom of the slider 7 to fit into the case 1, the board 5, etc., and a accommodating part 15 for the movable contact piece 8. A groove 16 into which the operating plate portion 9 of the operating element 3 is inserted is formed along the operating direction of the operating element 3. Note that since the slider 7 moves in a direction perpendicular to the operating element 3, in order to ensure that the operating plate section 9 is inserted into the groove 16 during all operations of the switch, the groove should be adjusted relative to the width of the operating panel section 9. 1
The length of slider 6 in the direction of movement must be made sufficiently large. Furthermore, a dogleg-shaped hole 17 is formed within the groove 16 . This hole has an appropriate inner diameter so that the upper and lower surfaces of the ball 12 disposed in the through hole 10 of the operation plate section 9 are guided by the inner wall of the hole.

る。G. Effects of the invention As described above, the push button switch of the present invention has a ball that fits into a through hole in the operator with its front and rear surfaces protruding, and a hole in the slider that allows the operator to reciprocate. By providing a dog-shaped hole in the inner wall of the groove to accommodate the front and rear surfaces of the ball, when the operator reciprocates, the upper and lower end surfaces of the ball move up and down under the control of the through hole, and The front and rear surfaces of the ball fit into the dogleg-shaped holes and move, and while the ball rolls freely, the slider reciprocates in a direction perpendicular to the vertical reciprocating direction of the operator. Since the slider movement direction changing mechanism is provided inside the slider, the movement of the slider becomes smooth and stable, the switch operation is performed smoothly and easily, and the reliability of the switch operation is increased.

好なものとすることができる。 In addition, since the ball placed on the control element is rotatable, when it is guided through the dogleg-shaped hole during switch operation, it rolls appropriately and creates friction, which makes it easier to operate the switch than with conventional sliding friction. A good feeling of operation can be achieved.
