Adam Silver argues against the use of toggle switches in user interface design. He discusses five main reasons why toggle switches can be problematic, including user comprehension issues, usability challenges, potential technical failures, inconsistency in design, and reliance on JavaScript.

Key points:

• Toggle switches can be confusing to understand their state

• There's risk of settings not being saved due to slow AJAX requests

• They require JavaScript to function, potentially compromising progressive enhancement

• Alternatives like radio buttons or simple toggle buttons are often better choices
