Two ways to use: Door Open,Light On or Door Closed,Light On.
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 ו- 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).
- איך זה עובד: 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).
- איך זה עובד: 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, closes when operated.
- NC (Normally Closed): Closed by default, opens when operated.
Understanding these terms is crucial for anyone working with electrical circuits and control systems, as they define how a switch functions in its resting state and when activated.
