An electronic device (20) includes a housing (24) and a rocking key button assembly (200) rockingly assembled to the housing. The housing includes a shaft portion (264) and a blocking board (268). The key button assembly includes a key button (30) having two opposite key portions (312), two elastic retaining members (40), two elastic arms (50) and two triggers (60). The elastic retaining members are retained to the shaft portion. The elastic arms resist against the blocking board. The key portions can rock relative to each other and about the shaft portion, the corresponding one trigger swings relative to the other trigger and about the shaft portion. The corresponding elastic arm is compressed by the blocking board. The elastic retaining members, the elastic arms and the triggers are arranged at the same side of the key button opposite to the two keys.
