Answer: To the signal governing movement over the switch

Feedback:
- Limits designated by a switch extend only to the signal governing movement over the switch, unless otherwise designated. - Track and Time does not have to use switches for limits but when it does, the signals become the reference points. - Switch Yes, you can be in the OS or on the switch; Switch No, the limits end at the signal before the switch; therefore, you cannot be on the switch or in the OS.
