I found this, in French, about the situation regarding deaf people in Switz:

It looks like you can be granted money to buy material, approved by the AVS/AI/AM/SUVA (although if you want more sophisticated stuff you can top up yourself the expense) which is a federal fund for which your participation is paid as a percentage of your salary (it covers old age pension, invalidity benefits and varous other things).
The list of cantonal offices is found here:

On a general basis, there seems to be plenty of stuff for deaf in Switz (about 200000 live there) particularly in term of support groups, I even found a Gay and Lesbian Deaf association
