Good question. According to the information found, it is possible that they are used to adjust the sensitivity of the left and right analogue sticks. These buttons, sometimes referred to as 'tension buttons', allow the user to adjust the strength of the analogue sticks according to their preferences. This can be useful for fine-tuning the control of the analogue sticks in certain games or for users who prefer a stiffer or softer feel when using the analogue sticks. It is also possible that these buttons have another function, such as calibrating the analogue sticks or restoring their default settings.

Unfortunately, this controller does not have this function. However, you can set the turbo to a button. On both sides. So it clicks for you as long as you press the button or you can switch it on permanently. Useful for clicker games and to always be the best at marioparty click games 😅

It has no motion sensors and no built-in batteries. Nevertheless, from my point of view, it's a must-have for gaming. I wouldn't give the pads away again!

No, does not have a corresponding sensor built in

This is the complete controller, central part, left and right side. As seen on the picture.

It does not seem that we can get it from our suppliers. We are sorry about that. :(

We expect that the controller does not need to be charged since it can only be used when connected to the switch.
