Knob and tube switches

My old house has extensive K&T that I'm slowly replacing. I'm familiar with new codes, practices, methods etc., But have no experience with k&t. Most of the rooms' light switches have simply two individual black wires coming in. One goes to the top of the switch, one to the bottom. That is all that's in the box. Does this mean the light fixture is getting power first?

Thanks in advance.
