  • the holding panel 10B, on which the respective operating buttons 20A to 20E are mounted, is attached to the body panel 10A, as is the case with Condition B. Consequently, as shown in Figure 3 , the contact sections including the distal ends of the pushing portions 24 and the portions being engaged 26 slightly push the elastically displaceable portions 54 of the elastic members 50 for the pushing switch to elastically displace the portions 54 slightly.

  • the pushing portion 24 and the portion being engaged 26 are pushed backward by the elastic recovery force of the elastically displaceable portion 54, and the portion being engaged 26 contacts with the engaging portion 16c of the deflectable piece 16 to stop moving. Accordingly, this position restricts a position where the operating button is returned. Furthermore, a slightly deflecting displacement of the engaging portion 16c at the time of contact can effectively restrain any noises caused by the contact (so-called bounding sounds). That is, the deflection of the deflectable piece 16 can contribute to facilitation of attaching the operating panel 10A to the holding panel 10B and restriction of causing the bounding sounds. In particular, since the engaging portion 16c of the deflectable piece 16 in the present embodiment contacts with the portion being engaged 26 in a direction inclined with respect to the inserting direction of the operating buttons 20A to 20E, the deflectable piece 16 is easy to deflect.

  • holding portions of the holding member hold the operating members, respectively and the holding members include a plurality of deflectable pieces that engage the portion being engaged of the operating members, respectively.
  • the positions of the pushing portion and the portion being engaged in the operating member are shared with each other, a whole construction of the device can be significantly simplified and downsized.
  • the present invention provides the above operating device and a switch apparatus including a switch element to be pushed by the pushing portion of the operating member that receives the pushing action in the operating device.
  • the switch element in the switch apparatus is adapted to apply a reaction force to the pushing portion in a direction opposite to the pushing action direction when the switch element is pushed by the pushing portion and is disposed at a position where the reaction force pushes the portion being engaged of the operating member to the engaging portion.
