Last week, I stepped through the basics of automotive electrical circuits, explained how electrical current needs to flow ...

Protective relays are critical power systems components, and it is essential to design and use them properly to detect power system issues. As NETA-certified technicians, we must be familiar with the ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Proper selection and effective testing can increase contact reliability in the end product while reducing the overall cost of using relays. Who said relays are pass�? While electromechanical relays ...

The relay's primary appeal is its ability to do a lesser-switch's bidding but it's capable of so much more. Relays can be wired together to create very useful, simple, and utterly reliable networks.

This white paper describes Coto's reliability testing of its Coto Classic reed relay and molded reed switches. For many switching applications reed relays remain the best solution, particularly when ...
