hja8630 - door lock mechanism needed?

Hi,
I'm searching around for a specific part for my dishwasher... The part that is broken is the little mechanism in the door that incorporates a 'lock' to keep the door shut, and includes a smash switch that tells the dishwasher that the door is open/closed.

(The plastic on my dishwasher has snapped, meaning the dishwasher thinks it's closed at all times, it still works, but will gladly spray it's water all over the kitchen as soon as I press the 'go' button, before closing the door).

If anyone could help me by telling me where I should go to buy one of these I'd be grateful. Ebay and google haven't yielded any results...

Thanks in advance for any help.
