The leaf buttons are taller than microswitch buttons. They are meant to operate differently.
When you rest your fingers on them... the button will sink down a little. If the leafs and contacts are too close... you might accidentally trigger them.
The correct way to use a leafswitch... is to press down just enough so that the contacts are barely touching...then lightly vibrate your fingers to break & re-establish connections...without need of full button travel.
As such, your fine.. and probably best off to have some space between the button and leafs. What you may want to tweak... is the space between the leaf contact points... if desired.
