This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

Pickering to include a new variant with an electrostatic shield between the switch and the coil to help minimise noise.

Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays use light to isolate the primary side, ...

Low-current, momentary action pushbutton switches, such as PCB-mount ‘tactile’ types, are cheap, and available in an abundance of different styles. Latching types, on the other hand, are often larger, ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

The company offers single-pole double-throw devices like the CCR-33, and a number of multi-throw versions. Coaxial switches are available as latching and failsafe versions. Depending on the impedance ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
