When the one end portion 22a is lowered, the opposite side of the key cap 21 that is engaged with the one end portion 22a of the first ^ member 22 (the side opposite to the pressing position of the working side shown in the drawing) is also subjected to the first link member 22 Pulling down I. Thus, even if the end portion of the keycap 21 is pressed, the keycap 21 is maintained in a horizontal state and lowered. The rubber dot 24 is bent by the lowering of the keycap 21, and the contact pressing portion 24a of the rubber ring = presses the contact 1 -6g of the diaphragm 26 as shown in Fig. 5 . Thereby, the movable contact 26e comes into contact with the fixed contact 2, and the closed shape is replaced.

It is also formed into a flat plate shape by the formation. The first link is in the first link member: the thickness of the button switching structure is reduced. The other end portion of the hole 3lf in which Hi1 is embedded is formed with a hole 31f. In the central part of the illusion of the component; ^=, the bulge of the 32 slaves. A member having a notch portion and a core portion 31 formed on the outer side of the first link and connected to the step portion is connected. *, the port 3le is a perspective view of the resin month for the second link resin 32. In Fig. 7, a first cut portion ± an upper portion is provided, and each of the key switches switches the structural support portion 32b and the contact hole 32c. 200845069 25192pif.doc :4= :: There are two rectangular members (cutting parts) 32d, divided into two 1 = divided parts) 32d by cutting the resin... - the part is protruding toward the vertical to form a vertical c figure ^ R : Corresponding to the setting, and fixing the other-end part stereo view.

The other components are the same as the implementation (4). Two: the operation of the button switching structure of example 2 and two The following operability is good for the key cut = 2; the 矣 structure is thinned, and even if the (4) key cap case can be maintained in a horizontal state, it is lowered. Next, the embodiment 3 will be described.

The missing M. is set to be used to indicate Example 3 is a perspective view of the tablet. In Fig. 10, 42c. The second support portion of the H-th inch portion and the contact hole are provided with two rectangular members (the cut portion M2d, the cut 3 Γ ί The portion 42 is formed by the embossed portion 41c of the upper portion of the rectangular member 42d and the two other end portions of the first link member 41. And the first support portion 2 of the third embodiment is shown in Fig. 11 (,), and the rectangular member _ cup 戸 D is attached to the other end portion 41C. The notch portion 42f is formed in the upper portion, and the rectangular member 42d is flexibly deformable in the upward direction. The rectangular member 42d and the first link member 41tr41e are as shown in Fig. 11(a), and the circle 2 at the other end portion makes the step 42e is embedded and fixed. That is, after the embedding, as shown in the figure, the front end portion of the embossed portion 42e is blocked and fixed. After the fixation, 200845069 25192pif.doc the mouth of the i-link member 41 The thickness of the plate 42 can be flexibly deformed in the direction of the arrow, that is, the tree is paralyzed. The other configuration is the same as that of the first embodiment. In the phase structure of the first embodiment, the following shandong mail only has the following operability of the key switch 21 (the key switching structure is thinned, and even if the key cap 1 is pressed, the key cap 21 can be turned to the horizontal state.

Further, a metal having elasticity may be used instead of the resin sheet. Further, in each of the above embodiments, the shape of the rectangular member as the cutout portion is a longitudinally long rectangular shape, but the shape of the cutout portion is of course not limited thereto. For example, as shown in FIG. 12(a), it may be a rectangular shape having a long lateral direction, and even if it is long in the longitudinal direction, as shown in FIG. 12(b), the corner portion may be an R shape. As shown in Fig. 12 (C), it may be a shape in which the corners are cut. Further, Fig. 12 (a), Fig. 2 a), and Fig. 12 (c) are perspective views showing a modified example of the cut portion.
