Use this interactive demo to learn how to apply the Switch function in an MS Access form.

Quick summary

The Switch function in MS Access lets you return different values based on conditional expressions, similar to a multi-branch If-Then logic. This tutorial shows how to add a text box to a form and bind it to a Switch function expression using the Expression Builder.

Steps

Open the form in Design View.
Add a text box to the form.
Set the Control Source by clicking the ellipsis icon in the property sheet.
Enter your Switch function expression in the Expression Builder and click OK.
Click the save icon to save your changes.

📌 Why this matters

The Switch function in Microsoft Access enables users to evaluate multiple conditions and return corresponding values within a single expression, replacing complex nested IIf statements. Mastering the Switch function helps database developers build cleaner, more readable forms and queries in MS Access. By binding a text box's Control Source to a Switch expression through the Expression Builder, users can display dynamic, condition-driven data without writing VBA code. This makes MS Access form development faster and more maintainable for both beginners and experienced database administrators.
