Yes no doubt something will fail eventually, it was in the house when

can probably get a new switch for around £15 if necessary.

£1.50 tops..

Yes but for the micro switch but the complete lock mechanism I can get
for under £15 so would probably buy that if it fails again.
After closer inspection I think what has happened is that over time the
`axle` that the cam is on has bent slightly as there is a strong pull
with a spring on that part and thats what is causing the contact issue
between cam and micro switch.
