immersion boost replacement

Hello

I am trying to find a replacement boost timer for my E7 immersion heater. I have written to the suppliers asking where I can source one from but I have received no reply. I have also searched the Internet but still unable to locate a supplier.

I wonder if any of you have bought one in the past, and if so I would appreciate any advise on where to start looking.

The timer is detailed here
