45 Amp shower switch red light always on?

Hi I have just put a new switch outside my bathroom for the shower. The shower works fine, however the red light on the 45 amp switch always stays on. Any ideas, the switch is from B&Q.

Thanks

You've put the supply into the load terminals & vice-versa.

It's nothing to do with where you bought it .
