Description of the invention: [Technical field to which the invention belongs]: The month of March relates to a sleeve having an operation portion protruding from a housing for accommodating a contact portion, and a push button switch having a frame that prevents the sleeve from falling off. [Prior art] As a conventional push button switch, it includes an operating body, that is, a sleeve, and a contact portion having a peripheral contact, a central fixed contact, and a movable contact is housed in a box-shaped casing, that is, a housing. The above-mentioned operating body includes a movable pressing unit and an operating portion protruding to the outside of the housing. The movable contact is formed in a dome shape, and is usually kept in contact with the peripheral fixed contact. In addition, the push button has an opening, which is a central hole that protrudes the operating portion of the sleeve, and has a cover, that is, a frame, which is fixed to the housing to prevent the sleeve from coming off. The frame is fixed to the housing by a fixing portion, that is, a riveting portion. 2. By pressing the sleeve, the movable contact is in contact with the central fixed contact. Thereby, the center fixed contact and the outer peripheral fixed contact are conducted by the movable contact, and the switch is turned on. In addition, when the sleeve is released from pressing, the movable contact is moved away from the center fixed contact. As a result, the center contact and the outer periphery @definite contact are isolated, and the switch is turned off (for example, refer to Patent Document 丨). The caulking portion is formed by, for example, inserting a convex portion formed in a housing into a hole formed in a frame, and then striking the convex portion with a punch to deform the convex portion. Accordingly, the riveted portion has a shape protruding from the upper surface of the frame. Further, in the operating portion of the sleeve, a pressing force is applied by a manually operated key. Generally, the face of the key head corresponding to the sleeve is provided larger than the face of the sleeve corresponding to the key head. 92577.doc 1234793 Patent Document 1: Japanese Unexamined Patent Publication No. Heikawa (paragraph No. 0014, Fig. 1). In the above conventional technique, in order to avoid interference between the underside of the key head and the riveting portion on the frame when the key is pressed, the height dimension of the riveting portion must be estimated to set the height dimension of the operating portion of the sleeve protruding from the frame.
