# Switch

### Overview

The **Switch** component allows conditional branching of messages based on predefined expressions. It evaluates up to five conditions (`out1` to `out5`) and routes messages accordingly. If none of the conditions match, the message is sent to the `else` output.

### Usage

#### Input Parameters

| Parameter                     | Type         | Description                                                        |
| ----------------------------- | ------------ | ------------------------------------------------------------------ |
| `expression1` - `expression5` | `expression` | Conditional expressions for respective outputs (`out1` to `out5`). |
| `else`                        | `default`    | Messages that do not match any condition are sent here.            |

Each expression supports **AND/OR logic**, allowing complex conditions.

#### Supported Operators

| Operator   | Description                                      |
| ---------- | ------------------------------------------------ |
| `=`        | Equal to                                         |
| `!=`       | Not equal to                                     |
| `>`        | Greater than                                     |
| `>=`       | Greater than or equal to                         |
| `<`        | Less than                                        |
| `<=`       | Less than or equal to                            |
| `%`        | Modulo operation (divisibility check)            |
| `empty`    | Checks if the value is empty                     |
| `notEmpty` | Checks if the value is not empty                 |
| `contains` | Checks if a value contains a substring           |
| `range`    | Checks if a value falls within a specified range |
| `regex`    | Matches a value against a regular expression     |

#### Output Parameters

| Output          | Description                                                       |
| --------------- | ----------------------------------------------------------------- |
| `out1` - `out5` | Message is sent to the first matching output based on conditions. |
| `else`          | If no conditions are met, the message is sent to this output.     |

### Instructions

1. **Define Conditions**
   * Configure up to 5 expressions (`expression1` to `expression5`) for routing messages.
2. **Set Operators**
   * Use supported operators to define comparison logic.
3. **Handle Default Cases**
   * If none of the conditions match, the message is sent to `else`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.appmixer.com/connector-configuration/utils/controls/switch.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
