Here’s an overview of the key components and how relay wiring is typically done:

Key Components of a Relay: Coil (Electromagnet): When current flows through the coil, it creates a magnetic field that activates the switch. Normally Open (NO) Contact: This is the contact that is open when the relay is de-energized. When the relay is activated, this contact closes. Normally Closed (NC) Contact: This contact is closed when the relay is de-energized. It opens when the relay is activated. Common (COM): This is the shared terminal for both the NO and NC contacts. Basic Wiring Steps: Coil Side: The relay coil is typically connected to a control circuit that energizes it. For example, it could be connected to a microcontroller, switch, or other control devices.
