After the movable contact 4 constituting the first switch part is pressed, a click feeling can be obtained when the slide member 4 slides on the sliding part 6g of the drive plate 6 and moves in the sliding direction. it can. In this case, since a click feeling can be obtained even when the second switch unit is input, the on-time of each of the two-stage switches can be accurately confirmed, and the operability is improved.

Next, the operation of the switch device of the present invention will be described with reference to FIGS.
First, in the initial state shown in FIG. 3, the slide member 7 is urged rightward in the drawing by the elastic force of the elastic member 9. At this time, the drive protrusion 7g of the slide member 7 is in contact with the holding recess 6f of the drive plate 6, and the drive plate 6 is attached upward by the elastic force of the bulging portion 4a of the movable contact 4 of the first switch portion. The top of the bulging portion 4a of the movable contact 4 is separated from the first individual fixed contact 2b of the first fixed contact 2, and the first switch portion is in an OFF state.

  Next, as shown in FIG. 4, when the slide member 7 is pressed in the left direction (arrow A direction), the slide member 7 moves to the left against the urging force of the elastic member 9, and the drive protrusion 7g. Is removed from the holding recess 6f of the drive plate 6 and rides on the sliding portion 6g on the distal end side. At this time, the drive plate 6 rotates counterclockwise (lower side in FIG. 4) with the rotation support portions 6 e and 6 e as fulcrums, and the bottom of the holding recess 6 f bulges out the movable contact 4 via the sheet member 5. By pressing the portion 4a, the bulging portion 4a is reversed downward, the top of the bulging portion 4a contacts the first individual fixed contact 2b, and the first individual fixed contact 2b and the first common fixed contact 2a are movable contacts. 4 is electrically connected to the first switch section. At this time, a click feeling is obtained by inverting the bulging portion 4a of the movable contact 4.

  At this time, FIG. 4 shows that the second individual fixed contact 3b constituting the second fixed contact 3 and the spring piece 8b of the sliding contact 8 are in contact with each other due to the cross-sectional position. Actually, they are arranged so as to be shifted in the direction perpendicular to the slide movement direction (the depth direction in FIG. 4), and the second switch unit is in the OFF state.

  Next, although not shown, when the slide member 7 is further pressed to the left (leftward in FIG. 4) from this state, the slide member 7 further moves to the left against the biasing force of the elastic member 9. Then, the drive protrusion 7g of the slide member 7 slides on the surface of the sliding portion 6g of the drive plate 6. At this time, the drive plate 6 is not rotated, and the state where the movable contact 4 is pressed by the bottom of the holding recess 6f of the drive plate 6 is maintained, so the first switch portion is maintained in the ON state. .

  Then, the sliding contact 8 fixed to the lower surface side of the slide member 7 is moved to the left by following the slide member 7, and the pair of spring pieces 8b, 8b of the slide contact 8 are connected to the first switch portion. In contact with the second common fixed contact 3a and the second individual fixed contact 3b constituting the second switch portion provided on the inner bottom surface in the vicinity of the inner wall surface of the storage portion 1a located rearward in the sliding direction, the second The common fixed contact 3a and the second individual fixed contact 3b are electrically connected via the sliding contact 8, and the second switch unit is turned on. At this time, if the above-described click generation portion is provided on the inner bottom surface of the slide member 7 and the storage portion 1a, a click feeling can be obtained even when the second switch portion is input.

According to the above-described embodiment of the present invention, the drive plate 6 that is driven by the sliding movement of the slide member 7 is disposed between the slide member 7 and the movable contact 4 and is rotatably held on the base 1. The movable contact 4 is pressed and brought into contact with the first fixed contact 2 by the rotation of the drive plate 6, and the movable contact 4 and the first fixed contact are contacted with the drive plate 6 after the movable contact 4 is pressed. Since the flat sliding portion 6g that allows the sliding member 7 to move in the sliding direction is further provided in a state where the contact with the movable contact 4 is maintained, the movable contact 4 is pressed and the first fixing is performed. Even after the contact 2 is turned on, the slide member 7 can be slid further, so that a large amount of operation of the switch can be ensured. Therefore, the operability is improved and an easy-to-use switch device can be provided.
Further, after the movable contact 4 is pressed, the driving projection 7g of the slide member 7 slides on the flat sliding portion 6g of the driving plate 6 and moves in the sliding direction while the first switch portion is turned on. In this case, since the second switch unit that can be operated is provided, a two-stage switch that can perform a plurality of inputs with a single switch device can be easily obtained.
