チと異なり特徴となるのは次の構成である。The push button switch of the second embodiment shown in FIG. 4 is different from the push button switch described in the above-mentioned prior art in that it has the following features.
【0034】即ち、皿バネと皿バネ駆動片とを一体と
し、図5に示す皿バネ12とした構成である。That is, the disc spring and the disc spring driving piece are integrated to form the disc spring 12 shown in FIG.
【0035】図5、図6において、皿バネ12は、外周

12の凸部から下方に延設するようにして駆動片12a
を設けても良い。駆動片12aの下端部は、板バネ8の
切起し部8aの腹部に当接する駆動突起12bとなる。In FIGS. 5 and 6, the disc spring 12 has a bowl shape with a circular outer periphery, a convex portion is located below, and a drive piece 12a is provided penetrating the convex portion. The drive piece 12 a is provided by penetrating the convex portion of the disc spring 12.
This is because the a and the disc spring 12 are firmly coupled to each other, so that the drive piece 12a extends downward from the convex portion of the disc spring 12.
May be provided. The lower end portion of the drive piece 12a serves as a drive protrusion 12b that comes into contact with the abdomen of the cut-and-raised portion 8a of the leaf spring 8.

て切起し部8aに当接する。When the drive projection 12b at the lower end of the drive piece 12a is pressed upward from below in the disc spring 12, the central portion is partially inverted into a dome shape to form a convex portion, which causes a click feeling. At the same time, it comes to have a biasing force. Further, the disc spring 12 is stored in the disc spring storage portion 3 a of the handle 3. Then, the driving piece 12a passes through the through hole 6a of the disc spring lid 6 and further through the opening 7a of the protective case 7, and comes into contact with the cut-and-raised portion 8a.

が導通状態となったことを知る。Then, as shown in FIG. 4 (b), the central portion of the disc spring 12 is inverted so as to have an upward convex portion to generate a click feeling, and also has a biasing force, and at the same time, a contact point. The movable contact 8d of the leaf spring body 8b pushed down by the pressing protrusion 6b comes into contact with the fixed contact 10a. Therefore, the operator knows that the fixed contact 10a and the movable contact 8d are in contact with each other by feeling the click feeling, and the push button switch is in the conductive state.
