As described above, the clearance C is secured between the small protrusion 23 a of the convex portion 23 of the pressing portion 2 and the upper surface 4 a of the base housing 4. For this reason, when the pressing area 2a of the pressing section 2 is pressed, the vicinity of the pressing area 2a of the pressing section 2 bends relatively easily. Therefore, the operator can easily and reliably recognize the operation. Further, even after the tip of the small protrusion 23a of the convex portion 23 comes into contact with the upper surface 4a of the base housing 4, if the pressing operation is further performed, the small protrusion 23a of the convex portion 23 has a certain repulsive force.

As described above, the clearance C is secured between the lowest point of the lowermost surface 24 a of the convex portion 24 of the pressing portion 2 and the upper surface 4 a of the base housing 4. For this reason, when the pressing area 2a of the pressing section 2 is pressed, the vicinity of the pressing area 2a of the pressing section 2 bends relatively easily. Therefore, the operator can easily and reliably recognize the operation. In addition, even after the lowest point of the lowermost surface 24a of the convex portion 24 and the upper surface 4a of the base housing 4 are in contact with each other, only a part of the lowermost surface 24a of the convex portion 24 is initially in contact. Therefore, the convex portion 24 is deformed relatively easily and the operator's finger or the like can be moved further in the pressing direction, so that the operator can recognize the pressing operation more effectively.
- the clearance C is secured between the apex portion 26 a of the convex portion 26 of the pressing portion 2 and the upper surface 4 a of the base housing 4. For this reason, when the pressing area 2a of the pressing section 2 is pressed, the vicinity of the pressing area 2a of the pressing section 2 bends relatively easily. Therefore, the operator can easily and reliably recognize the operation. Further, even after the apex portion 26a of the convex portion 26 and the upper surface 4a of the base housing 4 are in contact with each other, if the pressing operation is further performed, the convex portion 26 is easily deformed with a certain repulsive force, Since the operator's finger or the like can further move in the pressing direction, the operator can recognize the pressing operation more effectively. In particular, in this embodiment, since the convex part 26 is conical, compared with the cylindrical convex part 22, if it is the same member, it can deform
- the present invention can be used for a switch device that detects an operation in a pressing direction with respect to a pressing region, and can be used for, for example, an in-vehicle switch device.
