This is the replacement button switch for the Ascension 350, 500 and 620 CFM ventilators. A replacement switch is needed if the lights our power buttons fail.
The switch is excellent. The directions sent with the control made installing the new switch a breeze.

Hard to teplace
The new switch works fine. It was very hard to replace. There is no way to see into area you are working on. It is all by feel.took me and my wife over an hour to replace.Works fine now.
