のである。As shown in FIG. 1, a cylindrical portion 17 is formed on one surface of the case 1, and a push button 2 is inserted into the cylindrical portion 17 so as to be freely advanced and retracted. The case 1 is formed by combining a body 11 whose top surface is open in FIG. 1 and a cover 12 that covers the top surface of the body 1l. As shown in FIG. 2, the body 11 and the cover 12 are connected to an engagement hook 14 provided at the lower end of the leg piece 13 protruding from the lower surface of the cover l2 through an engagement hole drilled in the flange 15 of the body 11. 16 to be coupled. The body 11 is made of thermosetting resin, and the cover 12 is made of thermoplastic resin. According to this III precept, the cover is 12 for the body 11.
The case 1, which has an appearance as shown in Fig. 3, can be assembled by the simple operation of fitting the case 1 into place, making assembly easy. Furthermore, since no assembly frame is required, the number of parts is reduced. Inside the body 11, a movable side terminal 3a and a fixed side terminal 3b are housed. One end of a tension spring 4 made of a plate spring is fixed to the movable side terminal 3a, and a movable contact 6 is fixed to the lower surface of the other end of the tension spring 4. Further, the fixed side terminal 3b is provided with a fixed contact 7 that comes into contact with and separates from the movable contact 6. The push button 2 is provided with a pressing piece 2l projecting from the lower surface, and the lower end of the pressing piece 21 is brought into contact with the intermediate portion between both ends of the tension spring 4. Therefore, when the push button 2 is pressed downward, the tension spring 4 is pressed downward by the pressing piece 21, and the movable contact 6 comes into contact with the fixed contact 7. Here, the movable contact 6 in the tension spring 4
One end of a compression spring 5 made of a plate spring is integrally connected near the movable terminal 3a, and the other end of the compression spring 5 is held at a fixed position by a support piece 8 extending from the movable terminal 3a. The support piece 8 contacts the movable contact 6 near the point of force exerted on the tension spring 4 by the pressing piece 21.
The other end of the compression spring 5 is held in the middle of the vertical movement range of the tension spring 4 as the push button 2 advances and retreats. However, when the push button 2 is moved downward and the line segment connecting both ends of the compression spring 5 is located below the tension spring 4, the tension spring 4 is moved at the connection point between the tension spring 4 and the compression spring 5. The moment the movable contact 6 separates from the fixed contact 7 due to the resultant force of the compression spring 5 acting upward and the tension spring 4 comes to be located below the above-mentioned line segment, the tension spring 4 and the compression spring 5 The resultant force acts downwardly, causing the movable contact 6 to rapidly move downward and come into contact with the fixed contact 7. Moreover, if the pressing force on the push button 2 is removed, the movable contact 6 can be rapidly separated from the fixed contact 7 by the reverse operation. That is, a so-called snap action operation is performed, and the movable contact 6 can be moved at a constant speed regardless of the operating speed of the push button 2. By the way, the movable side terminal 3a and the fixed side terminal 3b each have a quick connection terminal structure, and as shown in FIG.
A terminal board 32 with a connecting piece 31 along the inner peripheral surface of the case 1
a locking spring 34 having a pair of spring pieces 33a and 33b having a spring force directed toward the connection piece 31; and a release button 35 that presses the spring piece 33b away from the connection piece 31 in response to an external force. It is equipped with A pair of locking springs 34 are provided for each terminal board 32, and a release button 35 is provided so as to come into contact with the spring pieces 33b of both locking pieces 34. A wire insertion hole 36 is formed in the bottom wall of the body 11 at a corresponding location between the spring pieces 33a, 33b of each locking spring 34 and the connection piece 31 of the terminal plate 32, and a pair of wire insertion holes are formed in the bottom wall of the body 11. A jig insertion hole 37 is bored between the holes 36 and 36, as shown in FIG. Therefore, when the electric wire 9 is inserted into the electric wire insertion hole 36 as shown in FIG. 32 are electrically connected, and the tip of the spring piece 33b bites into the electric wire 9, thereby preventing the electric wire 9 from coming off. On the other hand, when you want to disconnect the electric wire 9, as shown in FIG. This will push it away from the In this way, the electric wire 9 can be easily pulled out. By adopting the connecting terminal structure in this way, the work of connecting the electric wires 9 becomes easier. Also, since the live parts are not exposed to the outside, there is no need for conventional screw covers. Here, each terminal board 32 is provided with a pair of locking springs 3.
4 corresponds to each other, and a pair of wire insertion holes 36 are also provided, making it easy to send and wire. The push button 2 is made of urea resin containing fluororesin, and guide protrusions 22 are provided protruding from both sides of the push button 2, as shown in FIG. A portion of the guide protrusion 22 protrudes from the lower surface of the push button 2 to form a leg portion 22a, and a narrow sliding protrusion 22b extending in the vertical direction is protruded from a portion of the guide protrusion 22 corresponding to the side surface of the push button 2. ing.
This guide protrusion 22 is connected to the cover 1 as shown in FIG.
It is inserted into the guide ffil8 formed on the inner peripheral surface of the cylindrical portion 17 of No. 2 and running in the vertical direction, and the guide ? It is now possible to move up and down along II18. The upper end of the guide groove 18 is closed, and the upper surface of the guide protrusion 22 is connected to the guide arm 1.
8, the upper limit position of the movement range of pusher frJ2 is regulated. Guide here? 1l
18 and the guide protrusion 22, as shown in FIG. The circumferential surface of the cylindrical portion 17 is set so as not to come into contact with the opening of the cylindrical portion 17. According to this configuration, even if dust adheres around the push button 2, the frictional force with the cylindrical portion 17 does not increase, and combined with the fact that the push button 2 is formed of a material with a small coefficient of friction, the push button 2
can be operated smoothly. Further, a narrow sliding protrusion 22b is provided on the guide protrusion 22, and this sliding protrusion 22b comes into contact with the bottom surface of the guide shaft 18.
The contact area between the push button 2 and the cylindrical portion 17 is reduced, and this ellipse also provides a smooth operating feel for the push button 2. Furthermore, if the cover 12 has the same dimensions as the conventional one, the inclination of the push button 2 will be reduced, so there will be no difference in the operational feel no matter which part of the push button 2 is pressed. As shown in FIGS. 9 and 10, a label force bar 23 made of a transparent material is removably attached to the tip end surface of the push button 2. As shown in FIGS. The label force bar 23 is formed in the shape of a thin box with an open bottom, and a label can be held between the tip of the push button 2 and the label force bar 23. Here,
Since the label force bar 23 is held against the push button 2 by frictional force, a friction surface 24 formed by texturing is provided at a portion of the push button 2 that comes into contact with the peripheral wall of the label force bar 23. This arrangement increases the holding force against the label force bar 23. In other words, the label force bar 23 will not come off even when dropped, and can be easily removed by pulling with an appropriate amount of force.

できるという利点がある。As described above, the present invention includes a push button that protrudes from one side of the case so as to be able to move forward and backward, and a tension spring that is made of a plate spring and has a push part in the middle part that receives the pushing force from the push button, and has a movable contact at one end part. , a movable side terminal to which the other end of a tension spring is fixed, a fixed side terminal having a fixed contact whose movable contact comes into contact and leaves as the push button advances and retreats, and a fixed side terminal having one end connected to the tension spring near the movable contact. a compression spring whose end is fixed at a predetermined position near the movable contact in the vicinity of the push part, and the other end of the compression spring is located in the middle of the swing range of the tension spring in the forward and backward direction of the push button. In the structure of claim 1, the case is structured by a body and a cover, an engagement hole is formed in a flange protruding from the opening edge of the body, and an engagement hole is formed in the cover to engage with the engagement hole. Since the leg piece with the hook at the tip is provided protrudingly, the body and the cover are combined by inserting the leg piece into the engagement hole and fitting the cover onto the body. This has the advantage of simplifying the assembly work and eliminating the need for an assembly frame, resulting in a reduction in the number of parts. In addition, in the configuration of claim 2, the movable fill terminal and the fixed side terminal are each provided with a terminal board having a connecting piece, and a locking spring disposed opposite to the connecting piece and having a spring force in a direction to approach the connecting piece. and a release button that urges the locking spring away from the terminal board when external force is applied.One end of the wire introduced into the gauge through the wire insertion hole formed on one side of the case is connected to the connection piece. Since it is sandwiched between the wire and the MW spring, it has a so-called quick connection terminal structure, which has the effect of making it easy to connect the wire by simply inserting the wire into the wire insertion hole. Since it is not exposed, there is an advantage that there is no need to provide a member to cover the live part. Furthermore, in the structure of claim 3, guide protrusions are provided on both sides of the push button, and a cylindrical portion surrounding the push button is formed in the case, and a guide protrusion is formed on the inner circumferential surface of the cylindrical portion in the forward and backward direction of the push button. A guide groove is formed into which the guide protrusion is slidably inserted, and when the push button is tilted with respect to the cylindrical part and the guide protrusion abuts the inner circumferential surface of the guide groove, the circumferential surface of the push button and the inner periphery of the cylindrical part Since the guide protrusion has legs that regulate the inclination so that a gap is formed between the guide protrusion and the pushbutton, a gap can be maintained between the cylindrical part and the circumferential surface of the pushbutton even when the pushbutton is tilted. Therefore, even when dust is attached to the circumferential surface of the push button, no frictional force is applied to the cylindrical portion of the push button, and the push button can be smoothly operated.
