Normally Open (NO)

In the domain of pushbutton switches, the Normally Open (NO) type stands out as a fundamental design with specific characteristics and applications. When it comes to switch functionality, NO pushbutton switches are normally in an open state, meaning the circuit isn’t completed until the button is pressed. This type of switch utilizes a contact that’s open when at rest and only closes when actuated.

In circuit design, the Normally Open type is commonly used in applications where the circuit needs to be closed when the button is pressed, such as in turning on a light or activating a doorbell.

During the installation process, it’s important to understand that the NO pushbutton switch needs to be connected in a way that the circuit closes upon pressing the button. One common misconception is that these switches are always in an active state, which isn’t true; they’re only active when the button is pressed, completing the circuit.

Understanding the characteristics of Normally Open pushbutton switches is essential for designing circuits accurately and ensuring proper functionality.

Normally Closed (NC)

What distinguishes the Normally Closed (NC) type of pushbutton switches from the Normally Open (NO) counterparts? Normally Closed pushbutton switches are in a closed state when at rest, and they open when the button is pressed.

Here are some key points to take into account when utilizing Normally Closed pushbutton switches:

1. Switch Function: NC pushbutton switches are ideal for applications where the circuit should be closed in its resting state and opened when the button is pressed.

2. Circuit Applications: They’re commonly used in safety systems, emergency stop buttons, and alarm circuits where an immediate interruption is necessary.

3. Wiring Configurations: When incorporating NC pushbutton switches, make sure the circuit is designed to open when the button is pressed to achieve the desired functionality.
