You can treat it as an additional E-stop. In the "nope" position it will
light up the E-stop red lamp and will not allow the telescope to move.
Also the key can only be removed when in the "nope" position,
reciprocally this means that if the key is in the "yep" position it can
not be removed but the telescope is allowed to move.
Once the jib crane interlock is installed the same key will be used to
unlock the crane and allow it to swing into the path of the telescope
alt travel. Again the key can not be removed from the jib crane
interlock unless the crane is in the stow position.
All this translates to an effective mechanical interlock that will
prevent the jib crane from being in the path of the moving telescope.

Not only that, but unless the key is in and in the "Yep" position, it
acts
like the South Telescope e-stop.
