What do you mean by "blown"??
Did the switch just stop working or was the wiring charred and burnt?
The switch will be carrying a fair amount of current. If the connections are not made properly then they will burn out.
Make sure the cable ends are stripped back to bright copper and that the screw connections are done up as tight as possible.

Not really because you are not telling us whats happening!
Why did you need to change it? You say because it had "blown"?
What do you mean by this? What is "blown"? did the MCB or RCD operate? Is this what you mean by "blown" or did you hear a bang or something when you turned the switch on?
You really need to expand a little on what you mean and what happened.

I would double check all the connections on the new switch, dis-connect the feed to the shower, power up and see if the switch operates without tripping the breaker.
It sounds to me like you have connected to switch incorrectly.
