Lathe : 2nd turret over limit switch was created by vibram
Hello I have this specific setup where my secondary turret is beyond my limit switch. What are my option if I want to use it and I still want to keep my security up? Is there a was to disable temporarily the limit switch with a specific tool? Thank you

Limit switches probably can't and shouldn't be disabled.

Do you need a limit switch there?

So long as the machine is homed, it won't exceed the soft limits unless the computer goes completely rogue.

Hard limits are preferable, but not always 100% necessary.

Are your switches wired as normally open or normally closed?

For a normally open switch, you can just disconnect it.

For a normally open switch, just somehow short the connection so it never trips.

Though that could be pretty dangerous.

Disable a limit switch at your own risk!

I tried to do it correctly so I wired them as normally closed. I have 2 limit switches on the axis and this one is also my home switch. 
If I follow your advice then I need to revert everything to have the other LS as HS. This is not an issue to be honest, just thinking about the consequences.
