Magnetic switch is used to probe the door, window and drawer if opened illegally or mobile. It is composed of two parts: a wireless transmitter and a magnetic block.The magnet and the dry reed pipe are respectively arranged in the door frame (window frame) and the door leaf (window sash), which are basically embedded and installed.Magnetic switch including Door magnetic switch and Wordrobe Magnetic switch. Door magnetic switch: The preinstall Gallery lights will turn on while open door. Wordrobe Magnetic switch: The wordrobe light will turn on while open wardrobe.

Elton Santos, from the School of Mathematics and Physics at Queen's University, Canada, led his research team, and together with Stanford University, California State University, and the National Institute of Materials Science of Japan, successfully developed a new dynamic, lightweight, and durable device that The ultra-fast conductivity is unprecedented, and the device is easy to manufacture and can be used on a large scale in the quantitative manufacturing of semiconductor factories. 
Hexagonal boron nitride has good stability and electronic compatibility, and is insulated from graphene; while C60 converts sunlight into electricity. Smart devices made with this technology will have a variety of unique properties that are not inherently natural but are developed synthetically. Also known as Van der Waals technology, this technology combines a variety of composite materials and installs them in a predefined manner.
Elton Santos said: This new material has similar physical properties to silicon, but it has been greatly improved in terms of chemical stability, lightness and flexibility. Future smart devices will be able to apply this technology on a large scale and are durable and not fragile.
This device will be more energy efficient due to its unique device structure, which can improve battery life and reduce the risk of electric shock.
Elton Santos adds: We bring together top talents from all over the world, including the fields of chemistry, physics and materials, to conduct research and simulate predictions, how these materials work and how they solve everyday life. The questions in the course were thoroughly and professionally studied.
The study began with simulation predictions. Santos predicted that a combination of hexagonal boron nitride, graphene and C60 could develop a material with new physical and chemical properties. He then studied with Professors Alex Zettl and Professor Claudia Ojeda-Aristizabal from the University of California and California State University. The theoretical and experimental practice of this research is full of synergies.
The research was published in the journal ACS Nano, opening a new door for the exploration of new materials in the future. The problem that needs to be further solved is that graphene and new material structures still lack a kind of "band gap", which is the key to switch switching operation of electronic equipment.
The Santos team has now found a solution that uses a transition metal disulfide (TMDS) with better chemical stability and a band gap comparable to silicon. ( Compile: China Superhard Materials Network )
New graphene materials: making your mobile phone screen is no longer a nightmare
Abstract Most of the components of smart phones are made of silicon materials and other composite materials, which are expensive and fragile. According to statistics, in 2016, the global smart phone consumption was about 1.5 billion, so the huge consumption is really making the mobile phone Manufacturer's durable anti-fall performance in smart phones...
Most of the components of smart phones are made of silicon materials and other composite materials, which are expensive and fragile. According to statistics, in 2016, the global smart machine consumption was about 1.5 billion. Such huge consumption is really making mobile phone manufacturing. The company has a lot of thoughts on the performance improvement of the durable and anti-fall of the smart machine.
