I use a steam cooker for my daily meal. 
After intense usage of this household appliance, button enabling to power on (and launch timer) has broken.

I am still able to use steam cooker using a screwdriver, but user experience quality has dropped.

Thanks to CATIA V5, I have been able to design button in 3D. With 3DExperience lab, I will cut the part in red (see below), and will recreate a part (in green) to be pluged to main button.
