If your dogs are FCI pedigree, you will have a wealth of opportunities - just get in contact with the beardie club:

Or take a look at the SKG (Swiss Kennel Club - FCI) website:
http://www.hundeweb.org http://www.hundeweb.org/hundewebd/index.html http://www.hundeweb.org/hundewebd/tkgs/index.html http://www.tkamo.ch/
for a list of the various dog sports and clubs. You'll have to register your dog with the SKG, but as I understand it is relatively simple to register an 'ausland' FCI pedigree.
If your dogs, like mine, are not FCI, the options are more limited. Most dog sports are run through the SKG, and non-FCI dogs are generally not allowed to compete.

(Unless you have an already registered FCI dog - in which case you can complete with one non-FCI dog, but only one in your entire Swiss dog sport career.)
My youngster has passed the admissions trials for two local Agility clubs

, but we are waiting for a slot reserved for non-FCI dogs to open at either club. We might have a chance this summer or fall, or we might be years on the waiting list

- who knows. When a slot opens we will be able to train with the club, but will not be allowed to compete. (Which is fine by me - we do agility for fun, socialization, and 'brain training'.)
But, depending on where you live or how far you are willing to travel, you might find clubs with free capacity and be able to join right away.
As far as I know, there isn't a non-FCI agility league here (we belonged to a very active open league in the US). I've built an agility course in my garden for the time being... not optimal, but it gives the little hooligan a chance to have lots of fun, which is the whole point.
If I ever figure out the space, liability and bureaucracy issues, I might someday try to start an informal all-mutts-welcome Agility club...
My blind dog does tracking, but again, because he is not FCI we do not compete. We used to train with a club here, but I wasn't really happy with their training style - I mostly work with him on my own now. He's not so young anymore, so tracking is simply a fun way to keep him mentally and physically fit.
Where in Switzerland will you move to? I can look for a list of clubs in your area, if it would help... There are lots of dog clubs, some dedicated to one sport, some general training clubs, some all around clubs.
Edited to add - by rescue tracking, do you mean disaster rescue? If so, you might want to get in touch with Redog, the Swiss rescue dog association:
http://www.redog.ch/start_redog.php
I'm afraid I don't know anything about the group, other than they do a fantastic job.
Edited to add further:
You should also look into the new
Hundehalterbrevet:
http://www.hundehalterbrevet.ch/de/index.htm
This test was recently introduced as a sort of 'dog driving license', in response to the general public's growing fear of dogs following the Oberglatt tragedy. The test is at present voluntary, and all owners are encourage to take it. Many people believe that this test will become mandatory at some future point - who knows if that will happen, or not.
If your dogs do competative obedience the
Hundehalterbrevet will be a walk in the park for you.
My dogs are ...um... not up to that standard.

Yet.
