An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...

We show you how to wire in an electric fan relay kit with a thermostatic switch. If you've got an electric cooling fan on your classic car or hot rod and you want to know how to wire it with a relay, ...

Real switches and relays exhibit a finite resistance called “contact resistance,” which increases over time with the number of actuations. Furthermore, as a switch or relay changes state, the contacts ...

Found in a multitude of devices, relays are simple electromechanical switches featuring an electromagnet, one or more electrical contacts, a movable iron armature that is attracted by the magnetic ...

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 ...

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 FAN324x family of smart dual-coil relay drivers with integrated switches and wafer-level adjust capability for timing customization, is available in an 8-lead SOIC package and is part of Fairchild ...

Standex Electronics has created a reed relay that measures 7.95 x 4.67 x 3.6mm and can switch 100V, 200mA, 3W or 8GHz. 8GHz is the -3dB frequency, at which the switch offers -5dB isolation when open. ...

Ready-made wiring harness and relay kit makes it easy to add relays to a motorcycle headlight. Adding a relay can improve headlight output, reduce load on switches and allow higher wattage bulbs to be ...
