1. The Contact:
* Normally Open (NO) contacts are designed to be open in their default state. This means there is a gap between the two contact points, preventing electrical current from flowing.
2. Activation:
* When you activate the device (e.g., push a button, activate a switch, or apply a signal), the contacts close. This creates a continuous path for electricity to flow.
3. Wiring:
* The wiring for a normally open device is simple:
* One wire is connected to one contact point.
* The other wire is connected to the other contact point.
* These wires are then connected to the power source and the load (the device you want to control).
Here's an example:
* Imagine a light switch. The switch has normally open contacts.
* When you flip the switch, the contacts close, allowing current to flow to the light bulb and turn it on.
* When you release the switch, the contacts open again, breaking the circuit and turning the light off.
In summary:
* Normally open devices are designed to be open by default, preventing current flow.
* Activation closes the contacts, allowing current to flow and activating the device.
* Wiring connects the device's contacts to the power source and load, enabling current to flow when the device is activated.
