Further, since the boundary wall of the bottom wall is formed with a guide portion for supporting the slide member so as to slide along the boundary wall, the slide member can be made to slide smoothly, thereby providing a switch device having good operability.

Further, when the first coil spring is disposed between the slide member and the bottom wall, and the pressing operation of the slide member is released, the slide member is automatically returned to the initial state before the pressing operation by the action of the first coil spring. This good switch can be provided.

Further, the slide member forms a sliding surface having a stepped portion that is inclined in a direction parallel to the pressing operation direction, arranges a leaf spring that can be press-contacted to the sliding surface on the bottom wall side, and pressurizes the slide member to produce a leaf spring. By elastically deforming by this stepped portion, the pressing force to be pressurized is changed, so that a feeling of click due to the change of the pressing force can be felt, and a switch device having good operability can be provided.

In addition, the cover member and the bottom wall are formed separately, and the cover member has a lower side of the housing portion open, shields the lower side of the opened storage portion with the bottom wall, and seals the gap between the bottom wall and the cover member with a sealing material. Since it sealed and sealed the lower side of a accommodating part, liquid, such as water, can be prevented from invading from the bottom wall side.

Moreover, since the sealing material was also applied to the circumference | surroundings of the said 1st, 2nd fixed terminal attached to the bottom wall, the waterproof structure of the bottom wall side can be ensured more reliably.

In addition, since the dome-shaped rubber member is disposed on the operation portion of the slide member projecting outward from the cover member, and the upper side of the housing portion is sealed with the rubber member, liquid such as water also penetrates from the upper side of the cover member. It can prevent that, and can provide the switch apparatus of a reliable waterproof structure.

In addition, since the driving rod is disposed on the elastic member, and the driving rod is fixed to the operation portion of the slide member through the press-in hole formed in the rubber member, the slide member can be slid by pressurizing the driving rod. A switch device with good operability can be provided.
