SOLUTION: A disk with a flange is provided for the upper part 1 of a press button. This disk comprises a hollow center sleeve 4. One end part of the sleeve 4 is moved to the disk 3 to support the lower end part of a button 13 with the disk 3. A seal disk 26 is arranged between the disk 3 and the lower end part of the button 13 as a sealing means. In addition, a sealing means in the shape of a seal disk 27 is provided for the connecting region of the upper part 1 and a lower part 2. These sealing means protect against the entry of moisture content and dirt into the upper part 1. |
