20A Switches FAQ's

What's the difference between a 10A and 20A switch?


The main difference is the current rating. A 10A switch is commonly used for standard lighting circuits, while a 20A switch is designed for circuits with higher current requirements. The switch rating should always be suitable for the circuit and appliance it's connected to.

What are 20A switches used for?

20A switches are designed for circuits that require a higher current rating than standard light-switch circuits. Depending on the installation, they may be used for appliances and circuits such as electric heaters, immersion heaters, and some cookers or heating equipment. The correct switch will depend on the specific appliance and circuit, so always check the electrical requirements before choosing a switch.

Can I replace a standard light switch with a 20A switch?


A 20A switch shouldn't be chosen simply as a replacement for a standard light switch because the correct switch depends on the circuit and what it's controlling. Check the requirements of your installation and use a qualified electrician if you're unsure.
