Micro switch whats what?

To use the Grove - Micro Switch with just the common (C) and normally open (NO) connections, you’ll typically connect the following:

  1. Connect the “C” (Common) pin of the micro switch to your input/output device.
  2. Connect the “NO” (Normally Open) pin of the micro switch to your input/output device.
  3. Leave the other pins (“GND”, “VCC”, “NC”, and “D1”) unconnected as they are not required for your project.

This Types of drama configuration ensures that the common (C) terminal is always connected to the normally open (NO) terminal when the switch is in its default state. When the switch is activated (pressed or toggled), the circuit between “C” and “NO” is closed, allowing current to flow through your input/output device.
