The erroneous insertion prevention groove 86b prevents the incorrect insertion preventing portion 65 and the tongue piece member structure portion 70A from being mounted in an incorrect direction.

As shown in FIG. 10, the tongue holding member 86 includes an insertion hole 861 and click portions 862 and 862.
The insertion hole 861 is a contact part insertion hole through which the contact part 52 of the key member 50 attached to the key holding member 60 is inserted. The insertion hole 861 is formed in a long hole shape that is long in the slide movement direction (arrow Y1 direction) of the key member 50.

  The click portions 862 and 862 are formed on the inner surface of the insertion hole 861 so as to protrude from the inner surface. When the key member 50 moves between the first position PL1 and the second position PL2, the click portions 862 and 862 are in contact with the contact portion 52 at a predetermined position. Thereby, the click parts 862 and 862 give a click feeling to the user (operator).

The tongue piece member 70 is disposed between the contact portion 52 of the key member 50 and the sheet-like packing member 40 (see FIG. 12A).
As shown in FIG. 7, the tongue piece member 70 is indirectly fixed to the key holding member 60 via the tongue piece holding member 86 on the other end 70 b side. The tongue piece member 70 is indirectly fixed to the key holding member 60 on the other end 70b side so that one end side becomes the free end 70a.
Specifically, in the tongue piece member 70, the tongue piece holding member 86 is mounted in the holding member receiving recess 64 of the key holding member 60, so that the other end 70 b of the tongue piece member 70 is interposed via the tongue piece holding member 86. Thus, the state is indirectly fixed to the key holding member 60.

The tongue piece member 70 has a contacted portion 71 formed on the surface on the key member 50 side on the free end 70a side.
The contacted portion 71 is a raised portion (inclined portion) formed to protrude toward the key member 50 side. When the key member 50 is located at the first position PL1, the abutted portion 71 is not abutted against the abutting portion 52 as shown in FIG.
When the contacted portion 71 is located at the first position PL1, the tongue piece member 70 has a predetermined portion 70c (position closest to the switch member 30) on the free end 70a side as shown in FIG. The switch terminal portion 32 is not pressed via the packing member 40, or the switch terminal portion 32 is not switched over because the pressing amount does not reach the specified amount even when the switch terminal portion 32 is pressed (first state). Maintained.

Further, the abutted portion 71 is abutted against the abutting portion 52 when the key member 50 is located at the second position PL2 (see FIG. 12B).
When the key member 50 is positioned at the second position PL2, the free end 70a side of the tongue piece member 70 is moved to the switch side by the contact portion 52 being in contact with the contacted portion 71.
Specifically, when the key member 50 is located at the second position PL2, the free end 70a of the tongue piece member 70 is bent toward the switch terminal portion 32 side by the contacted portion 71 being pressed by the contact portion 52. The state is changed (second state).

  In other words, the tongue piece member 70 is bent and deformed so that the predetermined portion 70c on the free end 70a side moves to the switch terminal portion 32 side. In this case, the position of the predetermined portion 70c is located closer to the switch terminal portion 32 than the position in which the key member 50 is located at the first position PL1 due to the bending displacement of the free end 70a toward the switch terminal portion 32 ( Moving.

That is, the predetermined portion 70 c bends (displaces) the sheet-like packing member 40 toward the switch terminal portion 32 by displacement toward the switch terminal portion 32.
And the predetermined part 70c presses the switch terminal part 32 via the sheet-like packing member 40, and displaces the protrusion position of the switch terminal part 32. Thereby, the state in the switch member 30 is switched.

Next, the operation (operation) of the second slide key 19 will be described with reference to FIGS. 12A and 12B.
FIG. 12A is an explanatory diagram of the operation of the second slide key 19, and is an explanatory diagram of a state in which the key member 50 is located at the first position PL1. FIG. 12B is an explanatory diagram of the operation of the second slide key 19, and is an explanatory diagram of a state in which the key member 50 is located at the second position PL2.

As shown in FIG. 12A, in a state where the key member 50 is located at the first position PL <b> 1 that is the initial position (first state), the contact portion 52 of the key member 50 is in contact with the contacted portion 71. It is in a non-contact (non-contact) position.
The free end 70a of the tongue piece member 70 is in an initial state that is not displaced toward the switch member 30 side.
In this state, the sheet-like packing member 40 interposed between the tongue piece member 70 and the switch member 30 is not deformed.

In this state, the separation distance L <b> 1 between the packing member 40 and the switch body 31 is larger than the distance at which the switch terminal portion 32 switches the state (operation) of the switch member 30.
That is, the switch terminal portion 32 is not in the inclined position where the state (operation) of the switch member 30 is switched. Therefore, the switch member 30 maintains the initial state.

Next, a case where the user moves the key member 50 located at the first position PL1 shown in FIG. 12A to the second position PL2 shown in FIG. 12B will be described.
As shown in FIG. 12B, when the key member 50 is slid from the first position PL1, which is the initial position, to the second position PL2 (second state), the contact portion 52 of the key member 50 is in contact It abuts on the portion 71.

The free end 70a of the tongue piece member 70 is displaced toward the switch member 30 side.

When the key member 50 is moved from the second position PL2 to the first position PL1, which is the initial position, the contact portion 52 of the key member 50 is in a non-contact (not contacted) position with the contacted portion 71. Moved to.
Thereby, the free end 70a in the tongue piece member 70 is displaced to the opposite side to the switch member 30 side, and returns to the initial position.

In this state, the packing member 40 interposed between the tongue piece member 70 and the switch member 30 is deformed so as to be less bent with the movement of the predetermined portion 70c on the free end 70a side, and returns to the initial state.
As a result, the predetermined portion 70 c of the tongue piece member 70 is displaced from the position where the switch terminal portion 32 is pushed down toward the key holding member 60 via the packing member 40.

Here, the switch terminal portion 32 is moved by an urging member (not shown) so that the protruding amount from the switch body 31 is increased.
In this state, the separation distance L <b> 1 between the packing member 40 and the switch body 31 is larger than the distance at which the switch terminal portion 32 switches the state (operation) of the switch member 30.
That is, the switch terminal portion 32 has moved to the original position beyond the inclined position where the state (operation) of the switch member 30 is switched. Therefore, the switch member 30 is switched from a state different from the initial state to the initial state.

  Similarly to the above, when the key member 50 slides from the first position PL1 to the second position PL2, both side portions of the contact portion 52 come into contact with the click portions 862 and 862 of the tongue piece holding member 86. Get over the click part 862,862. At this time, a click feeling is generated in the key member 50. Then, the user can detect that the position of the key member 50 has been switched by a tactile sense (feel during operation).
