It is possible, What you do is you hit each switch twice like you are doing while keeping an eye on the time. If it starts to get low to back to the main platform to get the hour glass again and do it again. Keep doing that until you get the message that says now you have to get to the end to get the key. You jump up and over the cart and go on.
I'm still trying to get through level 3-8 The one that gives you 1 minute to get up to the top to get the key and the potion. I've only got one life and at one point there is no where to jump to when you reach a certain spot. I'd like to find a cheat for more lives so I can maybe have a chance to get throught that section.
