Narrative:
As we were descending on the arrival to cross a fix at 10;000' the a/C was in managed decent and managed speed. In the decent passing through 13;000' the a/C started to exceed the window of speed the fmcu had for that decent of 290 kts I reached down to start to deploy the speed brakes and as I was watching the speed and did not look down to confirm I had the correct handle started to deploy the speed brakes but in reality had selected the flap handle; as soon as I started to move the flap handle the flap overspeed sounded and I immediately replaced the handle to the stowed position; the flap handle was not in its transient position for more than approximately 3 seconds and never came close to reaching the flap 1 detent. Once we landed the captain called moc and wrote up the overspeed.
