Last month we discussed the basics of your car's 12-volt electrical system with the goal of understanding enough to trace problems to a particular electrical component. This month we're going to delve ...

Using Hall-effect technology, the DS Series solid-state switch is rated for 10 million operations. Supply voltage is 4.5 to 24 Vdc, and maximum supply current is 15 mA. Available with a button ...

A relay module is an electrical component. Various industries use this circuit board that houses one or more electric switches or relays in different circuits and electrical projects. Relay boards are ...

When to use mechanical vs. solid-state devices. The parameters that should be considered when selecting a device. Optimize your selection for lowest cost/maximum ...

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 ...

Hendon Semiconductors releases the IES5541A IC as the key component of a mains relay drive and relay contact protection circuit for effective arc suppression. It delivers effective arc suppression ...

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, ...

Menlo Microsystems unveiled its Ideal Switch recently and it also raised $150 million to shake up the electronics industry. It calls this the biggest innovation since the transistor, as it can power ...

Meet the Art Controller, a new dev board available over at Evil Mad Scientist Laboratories. It provides a drop-in solution for switching higher voltage loads (but not mains). The thing we like most ...

Outage stalled the Super Bowl in New Orleans for 35 minutes The cause of Sunday’s power outage at the Super Bowl in New Orleans has been traced to a newly installed electrical relay device meant to ...
