Very little pressure is required, it is actually gonna be tapping a screen on an iPad.

I plan to mount a capacitive touch pen to the motor.

Thanks.

Would a spinning motor with an arm and  something at the end be close enough to a "tap"? If you can get away with something that isn't perfectly straight then there are going to be easier options IMHO.
