# Switch component
A component that evaluates whether specified conditions are met and directs the follow of execution accordingly.
---
A **Switch** component evaluates conditions based on the output of specific components, directing the flow of execution accordingly to enable complex branching logic.
## Scenarios
A **Switch** component is essential for condition-based direction of execution flow. While it shares similarities with the [Categorize](https://ragflow.io/docs/dev/categorize_component) component, which is also used in multi-pronged strategies, the key distinction lies in their approach: the evaluation of the **Switch** component is rule-based, whereas the **Categorize** component involves AI and uses an LLM for decision-making.
## Configurations
### Case n
A **Switch** component must have at least one case, each with multiple specified conditions and *only one* downstream component. When multiple conditions are specified for a case, you must set the logical relationship between them to either AND or OR.
#### Next step
Specifies the downstream component of this case.
- *Once you specify the ID of the downstream component, a link is established between this case and the corresponding component.*
- *If you manually link this case to a downstream component on the canvas, the ID of that component is auto-populated.*
#### Condition
Evaluates whether the output of specific components meets certain conditions, with **Component ID**, **Operator**, and **Value** together forming a conditional expression.
:::danger IMPORTANT
When you have added multiple conditions for a specific case, a **Logical operator** field appears, requiring you to set the logical relationship between these conditions as either AND or OR.
:::
- **Component ID**: The ID of the corresponding component.
- **Operator**: The operator required to form a conditional expression.
- Equals
- Not equal
- Greater than
- Greater equal
- Less than
- Less equal
- Contains
- Not contains
- Starts with
- Ends with
- Is empty
- Not empty
- **Value**: A single value, which can be an integer, float, or string.
- Delimiters, multiple values, or expressions are *not* supported.
- Strings need not be wrapped in `""` or `''`.
### ELSE
**Required**. Specifies the downstream component if none of the conditions defined above are met.
*Once you specify the ID of the downstream component, a link is established between ELSE and the corresponding component.*
