Minit lathe - can you help ID my wiring?!

[HankMcSpank]

Thanks Peter, I couldn't find anything (well nothing less than £10 - for ten resistors...eeek!) , so I paniced, then got creative & 'rolled my own'. I happened to have some 29SWG enamelled copper coil wire lying about ....& I worked out that two strips of 31cm in parallel equals about 0.027 ohms, as apparently it's 0.173 ohm/mtr at 20C), here's a pic of the result....



& it actually works! My lathe is finally turning again!

Ok, so here's my final 'puzzle'

I've wired in a 'normally open' chuck guard switch provided (working on the theory that being new to lathes, if I don't have one of these I'll definitely end up with a chuck key in my cheek).

For the life of me I can't figure out how it can be 'triggered' (I only received a 'box of parts' from the seller)....there doesn't seem to be any cam/'sticky out bit' (technical term or what?!) on the chuck guard that can activate it the switch lever. Worse still the screws suggest the lever switch goes face down into the plastic recess hown in the photo below - that doesn't compute as there's no way in hell it can be 'activated' then!

If anyone has a mini lathe with a chuck guard switch setup similar to this, I'd really appreciate a photo/explanation of how it all fits together!
