What's a designer to do when challenged with a switching application that requires handling up to 70 kV? These applications are not as rare as one may think. In fact, a broad range of applications in ...

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 ...

In this circuit the 555 timer is used in a novel way, as a voltage controlled switch.The old and omnipresent NE555 can be very good at something it was not meant for: driving relays or other loads up ...

After seeing many projects that use microcontrollers to switch mains voltages [Rob Miles] decided to share his preferred method. The shots you see above are an enclosed relay, part number RIBTU1C ...

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

Pickering Electronics has launched electrostatic shielded variants of its high voltage Series 104 single-in-line reed relay family. The “optional electrostatic shielding between the switch and the ...

Pickering has introduced low-level switching variants of two of its series of high-voltage reed relays. Modifications of the 119 and 131 series, both Series 119L and 131L relay ranges have been ...

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 ...

This expert-authored comprehensive application guide outlines the vital role of insulation in safe electrical products and ...

[Teodor] writes in with a unique Tesla coil he designed and built. Unlike most Tesla coils, [Teodor]’s design is able to run with a fairly low input voltage because it doesn’t use a static spark gap ...
