Normally Open switches are used for what type of circuits?

Normally Open switches are primarily utilized in Open Loop circuits. When a Normally Open switch is in its default state, it does not complete the circuit; the circuit remains open until the switch is actuated. This is particularly useful in Open Loop circuits where the performance of the circuit does not rely on continuous feedback, allowing for straightforward control of devices. In these circuits, actuating the Normally Open switch completes the circuit and enables the operation of the connected device, making it clear that the switch design perfectly suits this application.

In contrast, Closed Loop circuits typically require continuous monitoring and feedback mechanisms, making the reliance on Normally Open switches less effective in such scenarios. Switching Circuits may use different types of switches depending on the application, and Resistance Circuits focus more on the resistance and current flow rather than switch configuration.
