[Operation of First Embodiment]
As shown in FIGS. 2 to 4, when the operating body 6 is held in the initial position, that is, in the non-operating position, the one end 4a of the coil spring 4 is elastically applied to the surface 2a1 of the first fixed contact 2a as described above. The winding portion 4 c of the coil spring 4 is held by the protrusion 5 c of the movable contact 5, and the other end 4 b of the coil spring 4 is supported by the spring receiving portion 5 b of the movable contact 5. As a result, the movable contact 5 is electrically connected to the first fixed contact 2a via the coil spring 4. However, the contact portion 5a of the movable contact 5 can be The second fixed contact 2b is kept away from the surface 2b1, and the second fixed contact 2b and the first fixed contact 2a are cut off and switched off. At this time, the inclined surface 7b of the holding member 7 is joined to the inclined surface 8c of the driving member 8 included in the operating body 6, and the driving member 8 forms a surface portion orthogonal to the sliding direction of the movable contact 5, for example. The one storage portion 1a is held in contact with one inner surface 1h. In this state, the coil spring 4 is slightly compressed to a length close to the natural length, and the elastic force of the coil spring 4 on the drive member 8 can be reduced. That is, the operating body 6 including the holding member 7 and the drive member 8 by the elastic force of the coil spring 4 is pressed against the above-described inner surface 1 h of the storage portion 1 a of the case 1 and the force based on the elastic force of the coil spring 4. Therefore, the force with which the holding member 7 and the movable contact 5 are pressed against the inner bottom surface 1g of the housing portion 1a of the case 1 can be extremely reduced.

  When the operation protrusion 8b of the drive member 8 is moved as shown by the arrow 10 in FIG. 2 from such a state, the groove 8g of the drive member 8 is guided to the wall provided in the lid member 9 and the drive member 8 The first guided portion 8e, the second guided portion 8f1, and the third guided portion 8f2 are guided by the corresponding ones of the locking portion 1c of the case 1 and the inner walls 1f1 and 1f2, and the driving member 8 slides. The operating force applied to the drive member 8 at this time is held via the inclined surface 8c of the drive member 8 and the inclined surface 7b of the holding member 7 in contact with the inclined surface 8c. It is transmitted as a sliding force of the member 7, the holding member 7 resists the elastic force of the coil spring 4, and the first guided portion 7c1 and the second guided portion 7c2 are the guide wall 1e and inner wall 1f2 of the case 1. By being guided to the applicable item Te slides in the arrow 10 direction in FIG. Further, the movable contact 5 slides integrally with the holding member 7 in the direction of the arrow 10 in FIG. 2, and the movable contact 5 is brought into contact with the inner bottom surface 1g of the housing portion 1a of the case 1 as shown in FIGS. The switch is turned on by contacting the surface 2b1 of the formed second fixed contact 2b.

  As described above, in the first embodiment, the movable contact 5 is slid through the inclined surface 8 c of the driving member 8 and the inclined surface 7 b of the holding member 7 that form the operating body 6, and the contact portion of the movable contact 5. 5a can be brought into contact with the surface 2b1 of the second fixed contact 2b, but when the operating force is transmitted from the inclined surface 8c of the driving member 8 to the inclined surface 7b of the holding member 7, the component force thereof, that is, the coil spring 4 The holding member 7 slides while being pushed in the direction of the second fixed contact 2b, which is an orthogonal direction different from the operation direction of the operating body 6, by the force based on the elastic force, that is, in the direction of the inner bottom surface 1g of the housing portion 1a of the case 1. . Further, as the holding member 7 slides, that is, by operating the operating body 6, the elastic force of the coil spring 4 to be compressed can be increased, and the operating force is correspondingly increased. That is, as the holding member 7 slides, the force based on the elastic force of the coil spring 4 described above becomes stronger, so that the contact portion 5a of the movable contact 5 held by the holding member 7 becomes the second fixed contact 2b. In contact with the surface 2b1, it is strongly pressed against the surface 2b1 of the second fixed contact 2b, whereby a desired contact pressure is obtained.

  Thus, when the contact portion 5a of the movable contact 5 contacts the surface 2b1 of the second fixed contact 2b, the second fixed contact 2b and the first fixed contact 2a are electrically compressed coil springs 4 and It conducts through the movable contact 5 and is switched on as described above.

  When the operating force applied to the drive member 8 is removed, the holding member 7 that holds the movable contact 5 and the drive member 8 are returned to the initial position by the elastic force of the compressed coil spring 4, and the movable contact 5 The contact portion 5a is separated from the surface 2b1 of the second fixed contact 2b, and the second fixed contact 2b and the first fixed contact 2a are cut off again, and the switch is turned off.

[Effect of the first embodiment]
In the first embodiment configured as described above, the movable contact 5 can be slid by the sliding operation of the operating body 6 as described above, and the movable contact 5 can be brought into contact with the second fixed contact 2b. During the sliding of the movable contact 5, the movable contact 5 is subjected to a force based on the elastic force of the coil spring 4 through the conversion means formed by the inclined surface 7 b of the holding member 7 and the inclined surface 8 c of the drive member 8. 2 Slide while being pressed in the direction of the inner bottom surface 1g of the case 1 where the fixed contact 2b is formed. In addition, the elastic force of the coil spring 4 compressed by the operation of the operating body 6 can be increased, and the movable contact 5 is pressed strongly against the second fixed contact 2b in accordance with the elastic force. Therefore, a desired contact pressure can be ensured even when the movable contact 5 does not have an elastic force. Thereby, it becomes possible to make the movable contact 5 into a small shape and dimension that does not require consideration of the elastic force for securing the contact pressure, and the switch device can be miniaturized.

  Further, during the sliding operation of the movable contact 5, the movable contact 5 is pressed against the second fixed contact 2b side by a force corresponding to the elastic force of the coil spring 4 through the converting means including the inclined surfaces 7b and 8c. Since it slides, the contact surfaces of the movable contact 5 and the second fixed contact 2b can be cleaned, and an excellent switch function can be secured.

  Further, in a state where the operating body 6 is not slid, the force based on the elastic force of the coil spring 4 converted by the converting means including the inclined surfaces 7b and 8c is weakened, and thereby the force applied to the movable contact 5 is weakened. Further, the force applied to the case 1 constituting the housing via the movable contact 5 is weakened, and when the switch device is soldered to the circuit board, the movable contact 5 may be sagged by heat or the case 1. Generation of distortion can be suppressed, and the reliability of the switch device can be improved. When the switch device according to the first embodiment is soldered to the circuit board, it may be soldered by reflow soldering, and the terminal 3a of the first embodiment is inserted into a hole formed in the circuit board. , 3b may be inserted and soldered by dip soldering. In any case, the above-described sag of the movable contact 5 can be suppressed.

  In the first embodiment, the operating body 6 includes a holding member 7 that holds the movable contact 5 and a drive member 8 that is separate from the holding member 7. Even when an undesired force such as bending is applied to the drive member 8 included in the operating body 6 during operation, such an undesired force is not directly transmitted to the holding member 7. Therefore, it is possible to protect the movable contact 5 held by the holding member 7 against an undesired force and the second fixed contact 2b to which the movable contact 5 comes in contact with and separates from.

It is done. That is, a force corresponding to the elastic force of the coil spring 4 compressed through the conversion surface can be smoothly transmitted as a force gradually pressing the movable contact 5 against the second fixed contact 2b, and high reliability can be secured. .

  Further, when the operating body 6 is slid, the drive member 8 and the holding member 7 can be brought into contact with each other by surface contact between the inclined surfaces 8c and 7b, and therefore, the shaving of these inclined surfaces 8c and 7b can be suppressed. Generation | occurrence | production of shaving powder can be reduced and it can be made hard to raise | generate the poor contact of the movable contact 5 and the 2nd fixed contact 2b by such shaving powder.

  In addition, since the contact portion 5a of the movable contact 5 has rigidity, the contact portion 5a of the movable contact 5 is moved to the first position by the force based on the elastic force of the coil spring 4 converted by the conversion means including the inclined surfaces 8c and 7b. 2 can be reliably pressed against the surface 2b1 of the fixed contact 2b, and a good contact pressure can be secured between the contact portion 5a of the movable contact 5 and the surface 2b1 of the second fixed contact 2b, and this also provides high reliability. It is done.

  The coil spring 4 has conductivity and returns the operating body 6 to the initial position, and the first fixed contact 2a and the second fixed contact 2b. The coil spring 4 includes the movable contact 5 and the first fixed contact 2a. Therefore, the coil spring 4 can be used as a conductive path in the switch operation. As a result, wiring routing can be simplified, and the structure of the switch device according to the first embodiment can be simplified. Further, the switch device can be easily assembled.

  Further, one end 4a of the coil spring 4 is supported by the exposed surface 2a1 of the first fixed contact 2a provided on the side surface of the housing portion 1a of the case 1 forming the housing, and the other end 4b of the coil spring 4 is movable contact 5. Since the winding portion 4c of the coil spring 4 is held by the projection 5c of the movable contact 5, the coil spring 4 is attached to the case 1 during the sliding operation of the operating body 6. It can be stably held in a compressed state in the storage portion 1a. That is, the coil spring 4 can be used as a stable conductive path in a compressed state, and high reliability can be ensured also by this.
