🔍 Key Concepts

• Difference between normally open (NO) and normally closed (NC) contacts in schematics • How a flow switch is drawn compared with level, pressure, or temperature switches • Interpreting the small paddle/flow indicator shape added to a basic switch symbol

💭 Think About

• First, decide which of the small pictures A–F is the flow switch, then match its function to the numbered contact symbols 1–14 • Look at each switch symbol: which one shows contacts that are closed when in the normal (no‑flow) condition, and will open when actuated by flow? • Among the specialized switch symbols (with triangles, paddles, or extra marks), which marking most clearly suggests fluid flow direction or a vane in a pipe?

✅ Before You Answer

• Verify which numbered symbols are closed in the normal position (the line between the two terminals is continuous) versus open • Identify which symbols include a vane/flow or piping-style shape instead of temperature bulbs or pressure bellows • Confirm that the symbol you pick represents a single-pole, normally closed contact modified only by a flow-sensing element, not by pressure, temperature, or level indications
