It uses a magnetic field as the driving force and has and high accuracy. After the contacts are closed, they can maintain a stable closed state through magnetic holding force. Even if the current in the coil disappears, the contacts still remain closed, providing reliable control signals, while also effectively saving energy and reducing the power consumption of the system. This Particularly beneficial for applications with long or frequent work hours. [Partition design, double insurance, ] 1. At the switch wiring area, we have installed a V0 flame-retardant PC circuit isolation board to avoid the intersection of lines and effectively the problem of short circuits caused by no baffle. 2. We also installed a circuit isolation board between the switch panel and the circuit board to avoid direct contact with the circuit board, which helps protect the equipment, protect your , and give you more peace of mind. [No neutral line required, simple installation] No neutral wire is required, meaning installation becomes simpler and more convenient. Users one complex step during the installation process, saving time and effort. For example, in some old buildings, there may be no neutral wiring reserved, but your product can still be installed and used smoothly. [No capacitor required, away from noise] Since there is no need to install capacitors, your product not generate current or electromagnetic interference, so it not generate noise, making it more convenient and quieter. [Magnetic latching relay, stable and energy-saving] Our smart switch uses a magnetic latching relay, which only needs to input current once to maintain the state. [2.5D curved tempered glass panel] Elegant appearance, classic colors can better match any home style. The panel is made of 2.5D curved tempered glass, which feels delicateand easy to clean. It is also moisture-proof, allowing it to work in humid conditions, preventing most accidents, making it and safe to use. 1. Three states: On by default, off by default, memory function. For example, the smart switch power-off memory function can record the last state of use. When the power is turned on again after a power outage, the switch automatically restore to its previous state without resetting. This saves users time and energy and improves convenience of use. You can also set the device status after power off and on again. 2. Offline reminder: Our smart switches also have a device offline reminder function, which can help users understand device status in a timely manner, improve device management efficiency, and effectively prevent device failures. 3. Device sharing: Through the device sharing function, member can easily enjoy the convenience of smart switches through their mobile phones. 4. Group control: Set up groups for smart switches and control multiple smart switches with a single through the app. For example, set up a "sleep group" and when you want to sleep, you can turn off all devices in the group at the same time with just one click.
