Can some one help me out with switch stick?

How to do it right and when to do it, thanks community

The first thing to do is make sure that you are usering a player in a coverage assignment, meaning that they are not blitzing. Once the ball is snapped, you can switch onto other players (in coverage assignments) by moving the right stick in the direction of the player you want to switch to. It is best to use the switch stick when in zone coverage. You usually use the feature when you see that a receiver is entering an unguarded area (ex. a corner route running overtop your hard flat). You could switch to the flat zone or deep zone to guard the route or bait an interception.
