2 ways to use according to your wiring (two terminals) method:
NC: Door Open, Light On
NO: Door Closed, Light On
Brief explanation of NC and NO:
When discussing switches, NC in NO refer to the two fundamental states of their electrical contacts:
1. NO (Normally Open)
- Meaning: In its default, unactuated state, the switch’s contacts are open, meaning the circuit is broken (off).
- How it works: The circuit only becomes closed (on) when you operate the switch (e.g., press a button, flip a toggle).
- Common uses:
- Start buttons: Most “start” buttons are NO. Pressing it completes a circuit to begin an operation.
- Doorbells: A classic example where pressing the button completes the circuit to ring the bell.
2. NC (Normally Closed)
- Meaning: In its default, unactuated state, the switch’s contacts are closed, meaning the circuit is complete (on).
- How it works: The circuit becomes open (off) only when you operate the switch (e.g., press an emergency stop button, open a safety gate).
- Common uses:
- Emergency stop buttons: These are typically NC. When activated, they break the circuit, immediately stopping machinery for safety.
- Safety interlocks: For instance, a switch on a machine’s guard door might be NC. If the door isn’t properly closed, the circuit is open, preventing the machine from operating.
Key Difference Summarized:
- NO (Normally Open): Open by default, zapre ob aktivaciji.
- NC (normalno zaprt): Zaprt by default, odpre ob aktivaciji.
Razumevanje teh izrazov je ključnega pomena za vse, ki delajo z električnimi vezji in krmilnimi sistemi, saj opredeljujejo, kako stikalo deluje v mirovanju in ob aktivaciji.
