Electric contact pair

I have a problem with my quite simple simulation. It is about a MEMS thermal actuated switch which should close and put in contact two biased electrodes.
The problem is that the simulation does not converge in the moment when the two parts (plate and electrodes) come in contact, and this seems to be due to the presence of Aluminum; in fact, in a previous version which is completely made of Silicon, things are apparently running in the right way.
I have tried many things (changes in the geometry, in the solver parameters, and in the definition of the contact and electrical pair) but I can't solve the problem, which disappears only when I return to a structure completely made of Silicon.
Can anyone help me? I really have no idea of what I'm doing wrong, but I feel like I'm missing something fundamental. Unfortunately I cannot upload the models because they are too big files (6 MB), does anyone know how to do it?
Thanks for help!
