Have you tried reglueing your switch back on, this was a fault with the varistream 2.
If not all the suppliers on here will post it to you, thats if they have any, they seem a little hard to get hold of at the moment.
I was just on the phone to pure freedom and they have them in stock, I asked about posting to your area, and there is no problem, he can have it in the post monday morning for you.
Just give him a call on 014723475.
