1. Choose a brand. The switches or sockets produced by small manufacturers are unreliable, have a short service life, and are not safe. Most well-known brands will make effective warranty promises to consumers. You can first follow multiple brands, then compare prices to understand reviews, and finally make a purchase;

2. Choose a style. The style and grade of the switch should match the overall indoor style, and choosing a suitable style can play a finishing touch. White is the mainstream, and the color of the switch panel should be coordinated with the overall color tone;

3. Look at the appearance and feel. Good sockets use materials with strong stability and are not easy to change color. The appearance surface is smooth and smooth, without bubbles, scratches, stains, uniform colors, and texture. It can be clearly seen with the naked eye and has a very good texture;

4. Weigh the weight. A good switch socket should have sufficient weight, and the copper plate inside the switch is the most critical part. If it is alloy or thin copper plate, it will not have the same weight and quality;

5. Look at the accessories. To fix the switch socket to the wall, screws need to be screwed to its base, and the firmness of this base will also affect the use of the switch panel. Some brands now use cold rolled steel plates to make this base, which will be more durable;

6. Inspection of goods. When the switch is delivered to the home, it should be carefully inspected. The product packaging should be standardized and complete, with exquisite design and printing. There should be clear trademark, manufacturer address, phone number, company website, and other information on it, including usage instructions and certificate of conformity, attachment screws, etc.
