Have you contacted the Schweizerischer Podologen Verband SPV?
A web address that will tell you about podiatry in CH is www.podologie.ch
The main problem will be getting your UK qualification recognised,as without it, the health insurances will not pay, so all work would have to be on a private basis.
The other area which maybe a problem is getting indemnity insurance, as our professional body ( the Society of Podiatrists and Chiriopodists) will not insure you to work outside the UK or at least that was the case. Switzerland is a special case as well, as it is not part of the EEC.
Hope that gets you started with your investigation!
