Mechanical switches might be the most common, but optical and magnetic switches also have their place on the market, offering unique advantages to gamers and professionals alike.

“When designing a security or access control system or specifying door protection, terms like ‘high security’ or ‘balanced magnetic switch (BMS)’ are no longer relevant,” he says.

Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are bulky, slow, expensive and/or waste energy. But that looks soon to ...

These switches operate as a transformer and are known as magnetic valve switches. The switches have two sets of two pins — one set for the primary and one for the secondary of the transformer ...

The researchers envision this breakthrough leading to ultrafast magnetic switches that can operate at room temperature — using lasers to control the lattice vibrations of a material.
