Mastering the n8n Switch Node: Your Ultimate Guide to Conditional Branching in Workflows

D: 🚀 Automation just got smarter! The n8n Switch Node is a game-changer for handling complex workflows with multiple conditions. Whether you’re filtering data, routing tasks, or creating dynamic automations, this guide dives deep into how to harness its power—with real-world examples, pro tips, and pitfalls to avoid.

🔹 What is the Switch Node?

The Switch Node acts like a “traffic controller” 🚦 in your n8n workflow. It evaluates data and directs the flow based on conditions you define. Unlike the IF Node, which handles binary (true/false) outcomes, the Switch Node supports multiple branches, making it ideal for:

• Routing emails by priority (e.g., “Urgent,” “Medium,” “Low”).
• Categorizing e-commerce orders by product type.
• Sending personalized responses based on user input.

🔹 How to Set Up a Switch Node

1. Basic Configuration

1. Add a Switch Node to your workflow.
2. Define Rules: Click “Add Routing Rule” and set conditions using:
   • Comparisons (=, >, contains, etc.).
   • Expressions (JavaScript snippets).
   • Data from previous nodes (e.g., {{$node["Webhook"].json["status"]}}).

2. Example: Prioritizing Support Tickets

Conditions:
- Rule 1: `{{$json["priority"]}} = "High"` → Connect to "Slack Alert" node.  
- Rule 2: `{{$json["priority"]}} = "Medium"` → Connect to "Email Team" node.  
- Default: Route all others to "Log Ticket" node.  

💡 Pro Tip: Use the “Default” branch to catch unmatched cases and avoid silent failures!

🔹 Advanced Techniques

1. Combining Multiple Conditions

Use AND/OR logic in expressions:

{{ $json["price"] > 100 && $json["customer"] == "VIP" }} → Route to "VIP Discount" node.

2. Regex Matching

Filter emails with patterns (e.g., /\bpromo\b/i for “promo” keywords).

3. Dynamic Branching with Code

Leverage the “Function” mode to evaluate complex JavaScript:

if (new Date($json["order_date"]) > new Date("2024-01-01")) {
  return "New_Campaign";
} else return "Legacy_Campaign";

🔹 Common Pitfalls & Fixes

❌ Mistake: Forgetting to handle null/unmatched data.
✅ Fix: Always set a Default branch.

❌ Mistake: Overloading with too many rules (slows performance).
✅ Fix: Use Function mode for >5 conditions.

❌ Mistake: Case-sensitive text comparisons.
✅ Fix: Normalize data first (e.g., {{$json["type"].toLowerCase()}}).

🔹 Real-World Use Cases

1. E-commerce Workflow:
   • Route orders to “Fulfillment” (in-stock) or “Backorder” (out-of-stock).
2. CRM Automation:
   • Send leads to “Sales” (budget > $10k) or “Newsletter” (budget < $10k).
3. Social Media Bot:
   • Reply with memes 😆 if message contains “funny”, else send FAQ link.

🔹 Switch vs. IF Node: When to Use Which?

Rule of Thumb: Use Switch for multi-path flows and IF for basic splits.

🎯 Final Tips

• Test conditions with the “Test Step” button.
• Document rules in node notes to avoid confusion.
• Pair with Error Trigger nodes to catch edge cases.
