[1] Operation as a slide operation type switch device FIG. 8 is a front view corresponding to FIG. 4A showing a state in which the operation member provided in the present embodiment is slid in the left direction. 9 is a perspective view corresponding to FIG. 6 in the state shown in FIG. 10 is a cross-sectional view corresponding to FIG. 7 in the state shown in FIG.

  The operation at the time of the slide operation of the operation member 13 will be described as an example in which the operation member 13 is slid in the left direction. The case in which the operation member 13 is slid in the right direction is the same as that in the left direction, and is omitted.

  When a leftward operating force is applied to the operating member 13 at the initial position, the movable contact 39 provided on the second conductive member 38 and the fixed contact 44 provided on the case body 2 are second regulated. Functions as a means. That is, the movement of the second movable member 18 is prevented by the movable contact 39 being in contact with the fixed contact 44. In this state, the operating member 13 moves together with the first movable member 17 while compressing and deforming the elastic member 19, and stops when the first movable member 17 contacts the second movable member 18.

  At this time, the movable contact 37 of the first conductive member 34 is in contact with the fixed contact 43 provided on the case body 2. Further, the movable contact 41 of the second conductive member 38 is separated from the fixed contact 45 provided on the case body 2. Further, since the elastic force of the elastic member 19 is dispersed by the first transmission portion 22 into a force that presses the second movable member 18 in the left direction and a force that presses the case body 2 in the direction of the back portion 2c. The movable contact 39 of the second conductive member 38 is pressed against the fixed contact 44, and the movable contact 37 of the first conductive member 34 is pressed against the fixed contact 43. As a result, the fixed contact 44 and the fixed contact 43 are conducted in a stable state via the movable contact 39, the elastic member 19 and the movable contact 37, and an electric signal corresponding to the operation of sliding the operation member 13 leftward.

The first and second movable members 17 and 18 come into contact with each other and are stopped by moving downward while moving toward each other against the elastic force.

  At this time, the movable contact 37 is in contact with the fixed contact 43, and the movable contact 41 is in contact with the fixed contact 45. Further, the elastic force of the elastic member 19 is transmitted to the first movable member 17 in the second transmission portion 24, so that the first movable member 17 is pressed in the direction of the back portion 2 c of the case body 2, thereby the movable contact 37.

As a result, the fixed contact 43 and the fixed contact 45 are conducted in a stable state via the movable contact 37, the elastic member 19 and the movable contact 41, and an electric signal corresponding to the push operation of the operation member 13 is generated. Will be.

  When the downward operating force on the operating member 13 is removed, the elastic member 19 returns while pushing back the first and second movable members 17 and 18 and the operating member 13. Accordingly, the movable contact 37 is separated from the fixed contact 43, and the movable contact 41 is separated from the fixed contact 45, so that an electrical signal corresponding to the push operation is not generated. Moreover, the force which presses the 1st movable member 17 in the direction of the back part 2c of the case main body 2, and the force which presses the 2nd movable member 18 in the direction of the back part 2c of the case main body 2 are removed.
