Wiring Diagrams for Four Way and Three Way Switches

  Home Electrical Question: I am having a senior moment. Does a three way switch connect the controls in 2 locations? Does a four way switch connect the controls in three locations? I’m preparing a lighting plan and cannot remember if this is the correct way to label the switching.

Thank you in advance!
