I am an electrical engineering student, so let me clarify your doubt about what is a 20 amp switch used for. A 20-amp double-pole switch is also known as an isolator switch. It is commonly used for high-power electrical appliances that require hard-wiring instead of plugging in. I have shared more information about this switch below.
What a 20 amp Switch Used For?
20-amp switches are often used instead of a switched fused spur when the connected load is above 13 amps or when an appliance has a high starting surge. In such cases, fuse protection is usually provided at the consumer unit.
Some 20 amp models come with a neon indicator or a cord outlet on the front. These switches ensure safe control and isolation of heavy-load devices, such as water heaters or ovens.
You can also choose a version with a neon indicator to show when the appliance is on, or one with a cord outlet for easy wiring.
Hope this helps you clearly understand what a 20-amp switch is used for.
