Hi Guys,
Is this the sort of limit switch you are looking for.
Attachment 385417
There are two circlip positions on the shaft, one as shown and one behind the spring, depending upon which way you want to activate it. Pushed from the left as in the drawing. The whole thing is mounted on a thin (1 mm) thick aluminium plate, drilled and bent up so the operating shaft slides through.
As far as getting stuff from China is concerned, I'm still waiting for the Honda ignition coil I ordered five weeks ago ! I've Emailed Banggood and they have replied, almost by return, that I have to wait for 40 days to claim non delivery. Their records show that it was sent the day after I placed the order and that it has arrived in the UK.
