Description of the invention (6) Opposite the pressing part 3 a, a movable dome-shaped structure is formed The contact point 5 is bent toward the fixed contact point 2 side, and the pressing protrusion 3 b is protruded downward. The sheet member 6 is formed of a sheet-like resin having elasticity, and is disposed so as to cover the opening portion of the casing 1, and is pressed by the pressing protrusion 3b and the movable contact 5 together. The frame 4 printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is made of flexible metal materials such as stainless steel and is formed in a shape of a small figure. The upper part of the frame 4 is provided with a protruding portion protruding outward. 4 a. In the center of the bulging portion 4a, there is provided a through hole 4b through which the rod 3 which is accommodated in the opening of the casing 1 to be movable is penetrated. The end portion is formed with a pair of arm portions 4 c facing each other. 4c in the arm. On the lower end side, a bridge connecting portion 4 is formed to form a rectangular window portion 4 d, and on the lower end side of the window portion 4 d, a bridge connecting portion 4, f is formed to be formed in the housing 1. The direction in which the concave portion 1 d protrudes is bent to be engaged with the protruding locking portion 4 e of the concave portion 1 d. The protruding locking portion 4 e may be formed in the frame 4 by bending in advance. However, after the frame 4 is engaged with the housing 1, the bridge portion 4 f may be directed to the recess 1 d. Distortion in direction. As shown in FIG. 9, the protruding locking portion 4e is protruded and deformed in the direction of the recessed portion 1d, and the width dimension of the lower edge of the window portion 4d is contracted and deformed inward, which is larger than the width dimension of the upper edge. W2 'Because the width dimension W i of the lower edge can be made slightly smaller, it is possible to absorb the width dimension of the hook portion 1 b when the side edges of the window portion 4 d are used to hold the hook portion 1 b' and the foregoing. The size difference of the width dimension of the window part 4 d can suppress the application of the Chinese national standard (CNS) A4 specification (210 X 297 mm) of the previous paper size. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 6 9 4 5 9 A7 B7 V. Description of the invention (7) The installation of the frame 4 is described above. —— In the above-mentioned embodiment, the hook portion 1 b and the recessed portion 1 d connected to the casing 1 are formed in the above-mentioned case, and formed continuously on the same surface below the hook portion 1 b and above the recessed portion 1 d. The locking surface portion 1 e ′ protrudes and locks the lower edge portion of the window portion 4 d of the frame 4 into the concave portion 1 d at the locking surface portion 1 e, and does not need to increase the protruding size of the hook portion 1 b. It is possible to obtain a strong engaged state, and to reduce the size of the housing 1 and the switch. Moreover, in the above-mentioned embodiment, the hook portion 1 b is provided so as to protrude from the outer side surface of the housing 1, but the present invention is not limited thereto. For example, it may be provided on the outer side surface of the housing 1. A hook portion lb that is more prominent than the outer surface is formed at the inner side of the outer surface so that the same effect as that of the above embodiment can be obtained. In addition, in the case 1, the hook portion 1 b is to be formed. Instead of the hook portion 1 b, the recess portion 1 d is formed to be deep, and the locking surface portion 1 e is formed in the recess portion 1 d. The aforementioned engagement structure of the protruding locking portion 4e of the frame 4 also allows the outer shape of the casing 1 and the switch to be enlarged, so as to obtain a strong engaged state. [Effects of the Invention] As described above, the push button switch of the present invention is provided with a recessed portion on the outer face on one of the opposite sides of the housing, and a protruding locking portion is provided on the arm engaging portion of the frame to lock the protrusion. The two parts protrude and engage in the recessed parts. The paper dimensions apply the Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before this page).

Invention Description (8) The ministry will not protrude from the outer shape of the housing and the switch, so it can try to miniaturize the housing and the switch, and can obtain a solid engagement state. In addition, since a pair of outer faces on one of the opposite sides of the housing are adjacent to each other, a hook portion is provided in the recessed portion, a window portion is provided in the arm portion, the hook portion is fitted into the window portion, and a lower edge portion of the window portion is formed by the hook portion. The lower locking is locked by both the hook portion and the concave portion, and the lower edge portion of the window portion of the arm portion is locked, so that the protruding size of the hook can be reduced, and the outer shape of the casing and the switch need not be enlarged. Strong engagement to prevent the frame from falling off, etc. In addition, since the hook portion and the recessed portion are arranged on the upper side and the recessed portion are arranged on the lower side, the hook portions and the recessed portions are continuously arranged side by side. The structure will not become complicated and simple, so the workability and assemblability of the parts are good. Furthermore, a locking surface portion formed of a continuous and same surface is formed on the lower surface of the hook portion and the upper surface of the recessed portion, and the locking surface portion is formed from the base portion located at the bottom of the recessed portion toward the front end of the hook portion. The opening is formed by an enlarged inclined surface. Since the inclined surface and the lower edge portion of the window portion of the frame are inserted into a strong fit, a stronger engagement state can be obtained than when no inclined surface is provided. In addition, since the protruding locking portion protrudes and deforms in the direction of the recessed portion, the width and size of the lower edge of the window portion are reduced, and the hook portions are held by the edges of the window portion to absorb the width dimension of the hook portion, and The size of the width of the window portion varies, and the installation of the frame can be suppressed.
