3-Way Switch Light Circuit Hand-Drawn Wiring Diagram - Travelers, 120V Hot, Neutral
Hand-drawn electrical wiring diagram of a three-way switch circuit with travelers, 120V hot, neutral and panel.
This is a hand-drawn wiring schematic (pen on paper) showing a standard three-way switch lighting circuit for 120-volt household wiring — not an automotive diagram. At the top of the page a light fixture is sketched with two terminals labeled H (hot) and N (neutral). In the middle of the page, two three-way switches are drawn with their traveler terminals joined by two parallel conductors labeled "Travelers." The common terminal of the right-hand switch is fed from a terminal labeled "120V Hot," which originates at a rectangle at the bottom right labeled "Panel" (the electrical service/breaker panel), which also shows a grounding symbol. A separate conductor labeled "Neutral" runs from the panel directly up to the light's N terminal, bypassing the switches. The common terminal of the left-hand switch carries the switched hot up the left side of the page to the light's H terminal. A reader can learn the basic current path of a three-way switch circuit: hot from the panel to one switch common, through either traveler to the second switch common, then to the light, with the neutral returning unswitched to the panel. No part numbers, wire colors, dates, or vehicle applicability information appear in the document.

Frequently asked questions
- What does this diagram show?
- A hand-drawn schematic of a light controlled by two three-way switches, showing the travelers between the switches, a 120V hot feed and neutral from a panel, and the light's H and N terminals.
- How are the two switches connected to each other?
- By two parallel wires labeled "Travelers" running between the two switches.
- Where does the neutral wire go in this circuit?
- The neutral runs directly from the panel up to the light's N terminal; it does not pass through the switches.
- Where does the 120V hot originate?
- From the box labeled "Panel" at the bottom right, feeding the common terminal of the right-hand switch through the terminal labeled "120V Hot."
- What voltage is this circuit?
- The diagram labels the hot feed as "120V Hot."
