ToggleSwitch class
The toggle switch represents a physical switch that allows users to turn things on or off, like a light switch. Use toggle switch controls to present users with two mutually exclusive options (such as on/off), where choosing an option provides immediate results.
Use a toggle switch for binary operations that take effect right after the user flips the toggle switch
Think of the toggle switch as a physical power switch for a device: you flip it on or off when you want to enable or disable the action performed by the device.
