Summary:A configuration that easily generates an operation sound and opening/closing of a contact at the same time or substantially at the same time, without increasing manufacturing cost. A push-button switch 1 having a sound function, wherein a button 11 accepts a pushing operation. A second plunger 13 slides in coordination with the pushing operation on the button 11. A torsion coil spring 14 stores or releases elastic energy together with sliding of the second plunger 13. A sounder unit 15 slides using elastic energy released by the torsion coil spring 14 at the same time as the torsion coil spring 14 elastically deforms, and the sounder unit 15 generates a hitting sound by impacting a hitting piece 181. A movable contact piece 16 has a movable-side contact Pm and is capable of moving due to being pushed by the sliding sounder unit 15. A fixed contact piece 17 has a fixed side contact Pf, the movable-side contact Pm being engaged with the fixed side contact Pf at the same time or substantially at the same time as the sounder unit 15 hits the hitting piece 181.
