During the Double 11 shopping festival, many people are preparing to buy big appliances like refrigerators. While online platforms offer great deals, it's important to choose wisely. Not all refrigerators on sale are suitable for your needs. How can you find the best one? Here’s a guide to help you make an informed decision.
First and foremost, consider the cooling technology. Many budget models use direct cooling, which might seem convenient because it doesn’t require manual defrosting. However, this method can lead to uneven temperature distribution and may not preserve food as effectively as air-cooled models. Air-cooled refrigerators ensure more even cooling and better freshness, making them a smarter choice for long-term use.
Next, think about capacity. It’s not just about how many people are in your family—it’s also about how you store your food. A large, well-organized refrigerator with multiple zones helps keep different types of food separate, preventing cross-contamination and odors. For a family of three, a 3-door model is ideal. If you have more family members or need extra storage, look for a model with more doors or additional compartments.
Temperature control is another key factor. A good refrigerator should maintain stable temperatures to keep your food fresh longer and reduce nutrient loss. Refrigerators with inverter compressors are especially beneficial, as they adjust power usage based on demand, leading to more precise temperature regulation and energy savings.
If you're looking for a reliable option, the Hisense BCD-519WTVBP is a great choice. It offers 519 liters of storage space, perfect for a growing family. Its slim design (645mm) makes it easy to fit into most kitchens without taking up too much space. The high-efficiency inverter compressor ensures stable cooling, while the 360° vector frequency conversion technology helps maintain optimal temperature. It's also energy-efficient, consuming only 1.09 kWh per day. Plus, it features a dedicated green purification compartment with catechins, vitamin C, and silver ions that help keep your food fresh and healthy.
Currently, this model is available on Tmall at a special price of 3099 yuan, with even more discounts expected during the Double 11 event. If you're planning to upgrade your fridge, this could be the perfect time to take advantage of the deal. Are you ready to shop? Let me know if you need more details!
Membrane Switch
What is a membrane switch?
A membrane switch is an operating system integrating key function, indicating element and instrument panel. The membrane switch, also called a membrane keyboard or membrane keypad, is a custom switch assembly that uses pressure to open or close the conducting path in an electrical circuit. The ultimate purpose of a membrane switch is to serve as the interface between man and machine, enabling an operator to communicate with a piece of equipment, instrument, or machinery. Membrane switches are still consistently utilized as user interfaces for a wide range of products from industrial machinery to medical devices to agricultural equipment. Even the most rigorous of industries can count on proven membrane switch technology to provide a reliable, long-lasting human-machine interface.
How about the construction of a membrane switch?
A membrane switch assembly differs from traditional mechanical switches. Membrane switches are essentially a sandwich of thin layers that are bonded together using pressure sensitive adhesives. The layers of a basic membrane switch construction include: a membrane overlay, spacer, printer circuit, rear adhesive, and tail filler. Other electronic components can be implemented, as well, such as discrete LEDs, backlighting sources, and connectors that make membrane switches easy to integrate into other systems or devices. Each layer in a membrane switch assembly serves a different purpose, and custom features require the addition of specialty layers. Depending on the environment and requirements of the application into which the membrane switch plugs into, the construction can vary.
