摘要： [Problem]To provide a two-stage switch which has few components, can be made thin, and can obtain a clear clicking sense.[Solution]A two-stage switch (10) is provided with a click dome plate (20) having a movable contact, a keypad (30) joined to the upper surface of the dome of the dome plate (20), and a fixed contact (41) formed on a substrate (40). The fixed contact (41) comprises a first stage fixed contact (42) and second stage fixed contact (43). When the keypad (30) is not being subjected to a pressing operation, the dome plate (20) is in a floating state without contacting any of the fixed contacts. With a first stage pressing operation on the keypad (30), the pad (30) is deformed and the dome plate (20) comes into contact with the first stage fixed contact (42). With a second stage pressing operation on the keypad (30), the dome plate (20) deforms with a clicking sensation and comes into contact with the second stage fixed contact (43).
