What is a reed switch?

چکیده
Since the reeds are ferromagnetic, the extreme ends will assume opposite magnetic polarity when brought into the influence of a magnetic field. When the magnetic flux density is sufficient, the attraction forces of the opposing magnetic poles overcome the reed stiffness causing them to flex toward each other and make contact. This operation can be repeated millions of times at extremely high speeds.

متن کاملEffect of Supplementing Common Reed (Phragmites australis) with Urea on Intake, Apparent Digestibility and Blood Metabolites of Baluchi Sheep
To evaluate the effects of treating or supplementing common reed (Phragmites australis) with 2% urea on intake, nutrient apparent digestibility, and blood metabolites, fifteen Baluchi rams (35.4±2.3 kg body weight) were used in a completely randomized design. Treatments were as follows: 1) common reed, 2) common reed supplemented with 2% urea solution at feeding, and 3) common reed tre...
متن کاملStudy of some growth traits of common reed )Phragmites australis( in Iran
Most of the research on Phragmites australis is restricted to sites on the European continent even though P. australis occurs abundantly in many regions in the Asian and other continents under different climatic and habitat conditions. The populations used in this study were collected from different parts of Iran. All these populations were grown in the same conditions in experimental field, lo...
متن کاملAnalysis and Design of a New Single Switch Non-Isolated Buck-Boost dc-dc Converter
In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...
متن کاملSimulation and Design of an Organic Quantum Film Electrooptic Switch
In this paper the simulation and design of a quantum-film electro-optic switch is considered. This photonic device, is made from a new organic dipolar material called MNA or 2-methyl-4 nitroaniline, which possesses a high merit in comparison with it's inorganic counterparts (e.g. LiNbO3, GaAs, InSb, Quartz, etc). Montecarlo method is used to simulate the photon-it-electron interaction in this m...
