Finance: UBS, Credit Suisse, Swiss Re
Consulting/Services providers: Deloite, IPT, TI&M, Even Accenture pays decent if you have a few years of experience, Stemford Consultants (that's more contracting though, but pay is certainly more than 100k)
Tech: Google, Microsoft, Swisscom, Avaloq (the last two are arguably not tech :p)
My problem with contracting is that it's often not too interesting and I also really appreciate a good social work environment. If I can have both, I'm in.
