I don't know why, but i got chord switching pretty quick when i first started learning. Only problem i had was with barre chords. Took me around 3 months to get them down whereas the normal chords switching took only 1 month.

Just practice switching each chord slowly, making sure your transition is smooth and articulate. Repeat it at a slow speed for a few times. Then start switching gradually faster. And don't have an order that you switch chords with. Try doing a G-E the first time, then change it randomly to a G-F or something. That makes you more comfortable switching from ANY chord to ANY other. Just keep at it and gradually build speed. If its messy, slow down again and perfect it. You'll nail it within a few weeks. Thats what i did when i first started out. Hope that helps.
