Baumatic BWD12 Faulty Door Lock

Hi.
We have an integrated washer dryer from Baumatic that stopped working because the door lock wouldn’t work. My last washer had a similar problem which turned out to be dirty contacts in the door lock switch. I’ve taken the switch out, cleaned the contacts and gone to put it back in again but my phone didn’t save the image of the order the wires were connected.

Can someone tell me which way round they go? The switch is a Metalflex ZV-446 T85 which has 3 pins. There is a blue wire (which I believe goes in the middle, and then there are 2 black wired connectors. One of the black wired connectors has 2 wires and goes towards the back of the washing machine via the wiring loom and the thinner single wired connector goes into the wash mode dial controller on the far right of the fascia. If I hold the door lock in the shape of a ‘Y’ which connectors go top to bottom please?

My fault for relying on technology rather than pencil and paper like I usually do. Any assistance very much appreciated.
