That seems quite expensive, as the switch is only about �10, you may be able to pull enough of the cord to put it in the on position, but I would reccomend that the switch is replaced because if something does go wrong with the shower you need to be able to isolate the supply quickly, I would ring another sparkie, if you go onto the" Napit" site you can search for a local electrician, or the eca or nic sites may also have this facility, I would have thought about �50, was a bit fairer, but obviously depends on travelling etc, good luck, Ray
