Brief explanation of NC and NO:

When discussing switches, NC dan 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, closes when operated.
• NC (Normally Closed/Tertutup Secara Normal): Tertutup by default, Membuka when operated.

Memahami istilah-istilah ini sangat penting bagi siapa pun yang bekerja dengan rangkaian listrik dan sistem kontrol, karena istilah-istilah tersebut mendefinisikan bagaimana sebuah saklar berfungsi dalam keadaan diam dan saat diaktifkan.
