linear motion

Hi, I have a huge problem and I hope you can help me with your experience. I'm desperately looking for a something that makes a stop to a rotating object and has very small dimensions. I immediately expose you better the problem even if it will not be easy, I am not able to provide you with a scheme, would further complicate understanding. I have a cover of a container for cosmetics of circular shape with diameter ø60 mm and 5 mm high. such lid has a tooth that exits from the bottom 5 mm high. the lid is placed in rotation through a suction cup that takes it from the top leaving the bottom uncovered. Now I have the nexisity to place the lid in a certain way (turning it) using the tooth mentioned above to stop it in the risk position for the application. I initially used a small flap piston to verify that the system worked but currently I have to make everything aesthetically more acceptable therefore I look for something that can replace the piston. If I can attach some photos as soon as possible. the piston would be placed above the cover and suction cup, under the engine, because the underlying part must remain discovered. I thought of replacing the piston with an electromagnet but I didn't find any significant benefits... I know that it is difficult to understand everything without a scheme but I guarantee that it would further complicate things. In the meantime, I'll train you something that at least lets you know what I'm talking about. I hope you can help me with some of your advice!

...the attached image is a prototype glass for the collection of the already made and tested cover. the part to which the suction cup is fixed thanks to a motor, therefore, on the support of the motor I also positioned the piston linked to a suitable sheet that, going down to the lid, I go to guarantee the positioning of the cover. After verifying that the system works, I must go to replace the piston because it is too large and therefore make the necessary changes that guarantee me an aesthetically acceptable system.

further question to ask you instead refers to the use of the tire in my grip system. Can you tell me where to find some rotational distributors? air must enter the fixed component and exit into the mobile component provided that the rotation of the latter is upstream of the fixed component.
