That looks the same as a Zanussi DW400 / Z30 dishwasher door interlock switch – the actuating lever is slightly different. If you can get one of those you can swap that quite easily.
If the door switch is the type that has a plastic rod pressing on the lever, then you can use SWT4720 from Connect and choose a lever to suit. It is possible – I have done it this way. 😉
Went back and changed switch yesterday – arrived with SWT4720 switch kit.. when I got into it after taking drum out and interlock assembly of it was just a bog standered micro switch fitted so fitted Hotpoint door interlock switch 168987.
Could have fitted switch from the kit but decided to keep on van for another day..
