可動部材20は、第1可動部材201と、第1可動部材201の上部に位置する第2可動部材202と、第1可動部材201及び第2可動部材202の間に配置される第3可動部材203とを有する。 Movable member 20 includes a first movable member 201, the third movable member and the second movable member 202 positioned above the first movable member 201 is disposed between the first movable member 201 and the second movable member 202 and a 203. 第1可動部材201は、端部が第2固定接点14と接している。 The first movable member 201, the end is in contact with the second fixed contact 14. また、第1可動部材201は、可動部材20が第2押下部材42に押下された場合に、中央部が第1固定接点12に接触する。 The first movable member 201, when the movable member 20 is pressed to the second pressing member 42, the central portion is in contact with the first fixed contact 12. 第1可動部材201、第2可動部材202及び第3可動部材203は、互いに接合されず、基板10及び固定シート16により形成される空間に個別に配置される。 The first movable member 201, the second movable member 202 and the third movable member 203 is not joined to each other, they are arranged individually in a space formed by the substrate 10 and the fixed seat 16.

第1可動部材201、第2可動部材202及び第3可動部材203は、略同一の形状を有し、且つ同一の素材で形成される。 The first movable member 201, the second movable member 202 and the third movable member 203 are substantially identical in shape, is and formed of the same material. また、第1可動部材201のバネ荷重と第2可動部材202のバネ荷重は等しい。 The spring load of spring load and the second movable member 202 of the first movable member 201 are equal. しかしながら、第3可動部材203のバネ荷重は、第1可動部材201及び第2可動部材202のバネ荷重よりも小さく設定されている。 However, the spring load of the third movable member 203 is smaller than the spring load of the first movable member 201 and the second movable member 202. 第3可動部材203のバネ荷重を第1可動部材201及び第2可動部材202のバネ荷重よりも小さく設定することにより、所望の耐久回数に到達する前に第3可動部材203が破損する可能性が小さくなる。 By setting smaller than the spring load of the spring load of the third movable member 203 first movable member 201 and the second movable member 202, a possibility that the third movable member 203 is damaged before reaching the desired endurance It becomes smaller.

第1押下部材40の表面が押下されてプッシュスイッチが押下されるとき、第2押下部材42は、第2可動部材202のドーム形状の頂点から鉛直方向に力が加えることによって第2可動部材202を押下する。 When the surface of the first pressing member 40 is a push switch is pressed is pressed, the second pressing member 42, the second movable member 202 by the force applied to the vertical direction from the apex of the dome shape of the second movable member 202 pressing the. 第2押下部材42によって押下された第2可動部材202は、第3可動部材203に接する面から種々の方向に力が加えることによって第3可動部材203を押下する。 The second movable member 202 is pressed by the second pressing member 42 presses the third movable member 203 by the force from the surface in contact with the third movable member 203 in various directions are added. このとき、第3可動部材203を押下する力は、第2可動部材202にも作用する。 At this time, the force of pressing the third movable member 203 also acts on the second movable member 202. 第2可動部材202によって押下された第3可動部材203は、第1可動部材201に接する面から種々の方向に力が加えることによって第1可動部材201を押下する。 The third movable member 203 is pressed by the second movable member 202 presses the first movable member 201 by force from the surface in contact with the first movable member 201 in various directions are added. このとき、第1可動部材201を押下する力は、第3可動部材203にも作用する。 At this time, a force pressing the first movable member 201 also acts on the third movable member 203.

第3可動部材203は、押下操作ごとに上下にそれぞれ位置する第1可動部材201及び第2可動部材202から互いに接する面を介して種々の方向から力が加えられることになる。 The third movable member 203, so that the force is applied from various directions through the surface contact with each other from the first movable member 201 and the second movable member 202 located above and below each depressing operation. 第3可動部材203は第1可動部材201及び第2可動部材202の双方から種々の方向から力を受けるために、押下操作ごとに表面及び裏面から種々の方向に応力を生じることになる。 The third movable member 203 will produce a stress on, in various directions from the surface and back for each pressing operation for receiving a force from various directions from both of the first movable member 201 and the second movable member 202. 一方、第2可動部材202を押下する第2押下部材42は部分球の頂点で押下するものであり、第1可動部材201は更に押下する部材がない。 On the other hand, the second pressing member 42 for pressing the second movable member 202 is intended to pressed on the apex of the part-spherical, the first movable member 201 is no member for further pressing. 第1可動部材201及び第2可動部材202は押下操作ごとに第3可動部材203から力が加えられるのみなので、生じる応力の方向は第3可動部材203より少ない。 Since the first movable member 201 and the second movable member 202 is a only a force from the third movable member 203 is added per pressing operation, the direction of the resulting stress is less than the third movable member 203. 第3可動部材203は押下操作ごとに第1可動部材201及び第2可動部材202よりも種々の方向からの応力を受けるため、第1可動部材201及び第2可動部材202よりも破損しやすい。 Since the third movable member 203 for receiving the stress from various directions than the first movable member 201 and the second movable member 202 for each pressing operation, easily damaged than the first movable member 201 and the second movable member 202.
