When to use

• Label should be visible to the left or right of the switch
• When clicked, the change should occur immediately
• When used as a part of a complex layout, it should be aligned with other elements in the row
• If it’s a part of a form, it should follow the same rules as other inputs (alternative UI: a 2 option radio button)

When not to use

• Do not use switch for “agree terms”
• Do not use switch without its label
• Do not use a group of switches with the same title where the on/off state of each switch is not clear
• If the system doesn’t support both states of the toggle, another control should be used
• Do not use a single switch for “additional” behaviors, such as “advanced search”. Use only when showing immediate effect, aka users could see the results without clicking on another call-to-action like save / submit.
