This is the lock switch of a DW New World dishwasher.
When the door is closed it wont operate, I have identified the problem
being that the micro switch isnt being `switched on` due to either the
micro switch or the operating cam is worn.
If I can increase the size of the red switch (see image) or the cam then
it should be DIYable.
Any ideas on what I could use to increase the size of either, I do have
some epoxy stuff and also hot glue (gun), I reckon if I can add 1mm
would it be enough to sort it.

Any suggestions.
