The sound deadening member 171 of the impacted member 17 has a shape in which substantially cylindrical shapes are stacked in two stages, and the outer diameter of the upper stage is formed to be longer than the outer diameter of the lower stage. A second tubular shaft portion 111 is fitted into the two-stage cylindrical sound deadening member 171. The sound deadening member 171 can be rotated around the second tubular shaft portion 111 extending vertically, and can be moved up and down by being guided by the second tubular shaft portion 111. The vertical movement range of the sound deadening member 171 is from the inner top surface of the movable member 11 to the upper surface of the sounding member 170.

An elastic portion 1710 made of soft rubber, a low-resilience resin, or the like is formed at the lower end of the sound deadening member 171 so as to face the impact member 15. The elastic portion 1710 is a portion that is hit by the striking member 15, but even if the striking member 15 is hit, the impact of the striking is absorbed, so that the generation of sound due to the striking is suppressed.

Inside the upper cylinder of the sound deadening member 171, an operated magnet 1711 using an annular magnet, which is a permanent magnet, is fitted as an operated portion that receives a non-contact operation from the switching magnet 2. The magnet 1711 to be operated is fitted in a direction of receiving a repulsive force due to a magnetic field from the switching magnet 2. A cam protrusion 1712 projecting outward is provided on the outside of the upper stage of the sound deadening member 171. The cam protrusion 1712 is a cam surface formed as a tapered slope on the upper side and the lower side, respectively. The sound deadening member 171 functions as a rotary cam by engaging the lower cam surface of the cam protrusion 1712 with the lower engaging protrusion 1700 of the sounding member 170. Further, the cam surface on the upper side of the cam projection 1712 engages with the upper engaging projection 113 (see FIGS. 8A, 8B, etc.) formed on the inner surface of the movable member 11, so that the sound deadening member 171 is a rotary cam. Functions as. Further, a plurality of regulation protrusions 1713 project from the upper surface of the sound deadening member 171. The regulation protrusion 1713 abuts on the inner top surface of the movable member 11 and regulates the rise of the muffling member 171 that is urged upward by the third urging member 172.

8A and 8B are schematic views showing an example of a part of the movable member 11 included in the key switch 1 described in the present application. 8A and 8B are views in which members such as the sound deadening member 171 are removed from the movable member 11 so that the inner top surface can be visually recognized. FIG. 8A is a schematic bottom view shown from a lower viewpoint, and FIG. 8B is a cross-sectional perspective view shown from an obliquely lower viewpoint. The inner top surface of the movable member 11 is an annular surface surrounded by a cylindrical wall surface inside the movable member 11 and formed around a central second tubular shaft portion 111. On the outer side of the inner top surface of the movable member 11, a plurality of upper engaging protrusions 113 having inclined surfaces inclined in the circumferential direction are formed at equal intervals along the circumferential direction, and the upper engaging protrusions 113 are formed. Engages with the upper cam surface of the cam projection 1712 of the muffling member 171. Among the inner top surfaces of the movable member 11, a plurality of receiving holes 114 into which the regulation protrusions 1713 of the sound deadening member 171 are fitted with play are recessed at equal intervals along the circumferential direction on the inner peripheral side of the upper engaging protrusion 113. It is installed. On the inner top surface of the movable member 11, the number of upper engaging protrusions 113 is twice that of the receiving holes 114. On the inner top surface of the movable member 11, the upper engaging protrusions 113 and the receiving holes 114 are arranged alternately so as not to overlap in the radial direction. However, since the number of the upper engaging protrusions 113 is twice the number of the receiving holes 114, there are positions where the receiving holes 114 are formed and positions where the receiving holes 114 are not formed between the upper engaging protrusions 113. ..

Returning to FIGS. 6 and 7, a third urging member 172 such as a compression coil spring is arranged around the lower stage of the sound deadening member 171 of the movable member 11 so as to wind the sound deadening member 171. The lower end of the third urging member 172 is mounted on a mounting table 1702 formed on the inner wall surface of the sounding member 170, and the upper end of the third urging member 172 presses the upper stage of the sound deadening member 171 from below. are doing.

In the impacted member 17 configured as described above, the sound deadening member 171 is relatively movable with respect to the sounding member 170 fixed in the movable member 11. That is, the elastic portion 1710 of the sound deadening member 171 included in the movable member 11 is relatively opposite to the rigid portion 1701 of the sounding member 170 included in the movable member 11 in the downward (first direction) and the pressing direction. It can move upward (second direction), which is the direction. When the elastic portion 1710 whose position can be changed relative to the rigid portion 1701 is located below the rigid portion 1701, the striking member 15 strikes the elastic portion 1710 of the impacted member 17. When the elastic portion 1710 is located above the rigid portion 1701, the striking member 15 strikes the rigid portion 1701 of the impacted member 17. When the striking member 15 strikes the elastic portion 1710, the impact at the time of striking is absorbed by the elastic portion 1710, so that the generation of sound due to the striking is suppressed. When the striking member 15 strikes the rigid portion 1701, a sound due to the impact at the time of striking is generated. Although the names of the objects to be impacted are described as the rigid portion 1701 and the elastic portion 1710, these names are relative meanings of the respective portions, and a sound due to vibration is likely to be generated when the impact is made. The one is called the rigid portion 1701, and the one that absorbs the impact of the impact and is less likely to generate sound is called the elastic portion 1710. Therefore, the rigid portion 1701 and the elastic portion 1710 do not absolutely limit the composition of the material, structure, shape, characteristics, and the like of these portions.

<Operation>
Next, the operation of the switch device described in the present application will be described. First, the operation at the time of the switching operation will be described. FIG. 9 is a schematic perspective view showing an example of a switching operation for the key switch 1 described in the present application. FIG. 9 shows a situation in which the switching magnet 2 is used to perform a non-contact switching operation (non-contact operation) with respect to the key switch 1. By bringing the switching magnet 2 closer to the key switch 1 from above, it is possible to switch between the generation and suppression of sound when the key switch 1 is pressed.

10A to 10E are schematic schematic views conceptually showing an example of a mechanism related to the switching operation of the key switch 1 described in the present application. 11A and 11B are schematic cross-sectional views showing an example of a movable member 11 included in the key switch 1 described in the present application, and an impacted member 17 and an engaging member 18 included in the movable member 11. 10A to 10E show an upper engaging protrusion 113 and a receiving hole 114 recessed in the inner top surface of the movable member 11 of the key switch 1, a lower engaging protrusion 1700 of the sounding member 170, and a cam protrusion of the sound deadening member 171. The arrangement of the 1712 and the regulation protrusion 1713 is shown as a schematic view developed on a two-dimensional plane.

FIG. 10A shows a situation in which the non-contact operation in which the switching magnet 2 is brought close to the magnet 2 is not performed. When the switching magnet 2 is not approached, the muffling member 171 is urged upward by the third urging member 172. The state shown in FIG. 10A shows a state in which the regulation protrusion 1713 formed on the upper surface of the sound deadening member 171 is fitted into the receiving hole 114 recessed in the inner top surface of the movable member 11. In the state shown in FIG. 10A, the sound deadening member 171 is raised by the third urging member 172 until it comes into contact with the inner surface of the movable member 11. FIG. 11A shows the positional relationship of various members in the state shown in FIG. 10A as a cross-sectional view. In the state shown in FIGS. 10A and 11A, in the impacted member 17, the lower end of the elastic portion 1710 of the sound deadening member 171 is located above the lower end of the rigid portion 1701 of the sounding member 170. Since the sound deadening member 171 is located above the rigid portion 1701, the impact member 15 strikes the rigid portion 1701 of the impacted member 17 from below, and a sound is generated at the time of impact.

FIG. 10B shows a situation in which the switching magnet 2 is brought closer to perform a non-contact operation from the state shown in FIG. 10A. The magnetic field generated by the operating magnet 20 of the switching magnet 2 causes the operated magnet 1711 of the sound deadening member 171 to receive a downward repulsive force. Since the repulsive force received by the operated magnet 1711 is strong enough to compress the third urging member 172, the sound deadening member 171 fitted with the operated magnet 1711 moves downward. When the sound deadening member 171 moves downward, the cam surface on the lower side of the cam protrusion 1712 of the sound deadening member 171 engages with the lower engaging protrusion 1700 of the sounding member 170, so that the sound deadening member 171 moves downward. As a result, it rotates in the circumferential direction with the vertical direction as the rotation axis. The rotation of the muffling member 171 is in the counterclockwise direction in the top view, and in the schematic schematic diagram shown in FIG. 10B, the muffling member 171 moves to the right.

FIG. 10C shows a situation in which the switching magnet 2 is separated from the state shown in FIG. 10B. By releasing the switching magnet 2, the repulsive force from the operating magnet 20 disappears, and the muffling member 171 is urged by the third urging member 172 and moves upward. When the sound deadening member 171 moves upward, the cam surface on the upper side of the cam projection 1712 of the sound deadening member 171 engages with the upper engaging projection 113 on the inner top surface of the movable member 11, so that the sound deadening member 171 moves upward. As it moves to, it rotates in the circumferential direction with the vertical direction as the rotation axis. The rotation of the muffling member 171 is in the counterclockwise direction in the top view, and moves to the right in the schematic schematic diagram shown in FIG. 10C. In the situation shown in FIG. 10C, since the receiving hole 114 is not recessed at the position corresponding to the regulation protrusion 1713 of the sound deadening member 171 on the inner top surface of the movable member 11, the regulation protrusion 1713 is inside the movable member 11. It abuts on the top surface and is restricted from moving upward. FIG. 11B shows the positional relationship of various members in the state shown in FIG. 10C as a cross-sectional view. In the state shown in FIGS. 10C and 11B, in the impacted member 17, the lower end of the elastic portion 1710 of the sound deadening member 171 is located below the lower end of the rigid portion 1701 of the sounding member 170. Since the sound deadening member 171 is located below the rigid portion 1701, the impact member 15 strikes the elastic portion 1710 of the impacted member 17 from below, and the sound generated at the time of impact is suppressed. Will be done.

FIG. 10D shows a situation in which the switching magnet 2 is brought closer to perform a non-contact operation from the state shown in FIG. 10C. Due to the magnetic field generated by the operating magnet 20 of the switching magnet 2, the operated magnet 1711 of the sound deadening member 171 receives a downward repulsive force, and the sound deadening member 171 moves downward. When the sound deadening member 171 moves downward, the cam surface on the lower side of the cam protrusion 1712 of the sound deadening member 171 engages with the lower engaging protrusion 1700 of the sounding member 170, so that the sound deadening member 171 moves downward. As a result, it rotates in the circumferential direction with the vertical direction as the rotation axis. The rotation of the muffling member 171 is in the counterclockwise direction in the top view, and in the schematic schematic diagram shown in FIG. 10D, the muffling member 171 moves to the right.

FIG. 10E shows a situation in which the switching magnet 2 is separated from the state shown in FIG. 10D. By releasing the switching magnet 2, the repulsive force from the operating magnet 20 disappears, and the muffling member 171 is urged by the third urging member 172 and moves upward. When the sound deadening member 171 moves upward, the cam surface on the upper side of the cam projection 1712 of the sound deadening member 171 engages with the upper engaging projection 113 on the inner top surface of the movable member 11, so that the sound deadening member 171 moves upward. As it moves to, it rotates in the circumferential direction with the vertical direction as the rotation axis. The rotation of the sound deadening member 171 is in the counterclockwise direction in the top view, and moves to the right in the schematic schematic diagram shown in FIG. 10E. In the situation shown in FIG. 10E, since the receiving hole 114 is recessed at the position corresponding to the regulating protrusion 1713 of the sound deadening member 171 on the inner top surface of the movable member 11, the regulating protrusion 1713 fits into the receiving hole 114.
