Push button switches are essential components in modern electronic devices, allowing users to interact with equipment seamlessly. However, delving into the realm of push button switches might introduce terms like “NC” and “NO,” which could initially appear puzzling. Let’s dispel this confusion and gain a clear comprehension of their significance.
‘NC’ – Normally Closed: In the context of a push button switch, ‘NC’ stands for “Normally Closed.” This indicates the default state of the switch contacts when the button is untouched. In this state, the circuit between the ‘NC’ terminals is complete, enabling the flow of current. Upon pressing the button, the circuit opens, disrupting the current flow.
‘NO’ – Normally Open: ‘NO’ represents “Normally Open,” characterizing the state of the switch contacts when the button is unpressed. In this scenario, the ‘NO’ circuit remains open by default. Pressing the button initiates the closure of the circuit, permitting the current to traverse through the switch.
Comprehending the roles of ‘NC’ and ‘NO’ configurations is pivotal in selecting the appropriate push button switch for specific applications, whether they entail safety measures or control functionalities within electronic systems.
