Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

This low current relay circuit is designed to be used in battery operated electronic devices. Its operating current is in micro amperes (µA). This is done by using a bistable relay and adding some ...

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 essence of the circuit is for the input of tone and signal to provide an activation for the relay switch. Relay – an electrically operated switch where the current flowing through the coil of the ...

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, ...

Begin by connecting pin 85 of the relay to a clean ground point on the vehicle chassis or the negative terminal of the ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...

Infineon Technologies has launched an ultra-low resistance high-side switch in a 9.9 x 11.7 x 2.3mm surface-mount package. For automotive use on 12V circuits, the IC is “ISO 26262-ready for supporting ...

In the first part of this electrical troubleshooting series, we discussed how a consistent approach to electrical troubleshooting can help HVAC technicians get a comprehensive assessment of what is ...

Q. What type of circuit breaker does the Code allow to be used for switching duty of lighting circuits? A. Circuit breakers used to switch 120V or 277V fluorescent lighting circuits must be listed and ...

Fran: Ahhh, I almost won that one as well! Now, our appliances and devices, they all work because of the electrical current that flows into them through a circuit. An electrical circuit is made of a ...
