<p>[Problems] This is to provide a two-step switch which has few number of parts, can be made thin and can obtain a clear click feeling. [Solving means] A two-step switch 10 has a click dome plate 20 which is a movable contact, a keypad 30 joined to an upper surface of the dome of the dome plate 20, and a fixed contact 41 formed on a substrate 40. The fixed contact 41 has a first-step fixed contact 42 and a second-step fixed contact 43. In a state in which the keypad 30 is not subjecting to pressing operation, the dome plate 20 is in a floating state without contacting any of the fixed contacts. By a first-step pressing operation of the keypad 30, the pad 30 is deformed and the dome plate 20 is contacted with the first-step fixed contact 42, and by a second-step pressing operation of the keypad 30, the dome plate 20 is deformed accompanied by a click feeling to contact with the second-step fixed contact 43.</p> |
