Reed switches can be used to directly switch a variety of loads ranging from nanovolts to kilovolts, femtoamperes to amperes, and DC to radio frequency. Other magnetically-activated switching devices have a limited range of output voltages and currents, and generally do not directly control a final device such as a lamp, solenoid, or motor.
Very early computers often stored bits in a magnetically latching relay, such as ferreed or the later remreed in the 1ESS switch. Some early computers used ordinary relays as a kind of latch —they store bits in ordinary wire-spring relays or reed relays by feeding an output wire back as an input, resulting in a feedback loop or sequential ...
A reed relay [i] is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them. Sealed in a long, narrow glass tube, the contacts are protected from corrosion. The glass envelope may contain multiple ...
This week, a project called BusKill launched a custom USB magnetic breakaway cable that acts as a “dead man’s switch,” locking a computer if someone physically snatches it and severs the ...
Mechanical switches are very different. They rely on magnets and springs and activate by sensing changes in the magnetic field. Popularized by Dutch keyboard startup Wooting, these switches rely ...
Magnetic storage. Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads .
Magnetic switch. Magnetic switch is an electrical switch that makes or breaks contact in the presence of a magnetic field.Applications include situations where it is not desirable or possible for moving elements to make direct contact with the switch, such as in explosive environments, submerged in liquids, and where repetitive contact with a mechanical switch would result in undesired wear.
The Ayaneo Kun is among the most decadent Windows handhelds we’ve tested. With a sharp 8.4-inch display, a powerful Ryzen 7 7840U chip, up to 64GB of RAM, up to 4TB of storage, a huge 75Wh ...
