Steam Deck Left Thumbstick

This is a Type A Left Thumbstick.

Each Steam Deck ships with one of two different models of thumbsticks, Type A or Type B. Although nearly identical, capacitive touch capability relies on the correct type to be installed. To identify which replacement thumbsticks you need, navigate to Settings → System and check the Steam Deck Controller ID.

• If the Controller ID starts with “MEDA” that device uses a Type A thumbstick.
• If the Controller ID starts with “MHDA” that device uses a Type B thumbstick.
