Scratchy 1C Hook Switch?

The rotary 1C I am working on is finally mostly alive. When I take the receiver off hook, I get a dial tone. If I hang up and pick up again, I don't always get another dial tone. I can see that when I hang up the line is disconnecting because the light on my line simulator goes off. When I pick up and don't get dial tone, the line is active but no dial tone. Could the hook switch be causing this?
