What is better to use for a toggle switch with two states (on/off): toggle or checkbox?

For a two-state switch (on/off), it is better to use toggle if you want to emphasize interactivity and mimic a physical switch. Toggle is usually used to control states that affect the application's behavior.

Checkbox, on the other hand, is traditionally used for selecting or marking options in lists and forms.

Main differences:

• Toggle — visually resembles a switch, immediately shows the current state, suitable for turning functions on/off.
• Checkbox — a square element, more often used for multiple selections, less obvious for binary switches.

If the task is simply to turn an option on or off, it is better to use toggle for better UX.
