Oct 31, 2023 · Relay basics – an introduction to relay history, functions, types, and choice.

It consists of a coil of wire surrounding a soft iron core, an iron yoke, which provides a low reluctance path for magnetic flux, a movable iron armature, and a set, or sets, of contacts. The …

Mar 11, 2021 · Relays are electromechanical switches designed to control one or more circuits by opening or closing contacts in response to an electrical signal. They enable low-power signals …

Sep 11, 2024 · Instead of mechanical operation, a relay deploys an electrical signal to drive an electromagnet, which in turn engages or breaks (connects or disconnects) another circuit. …

Relay coils produce brief high voltage 'spikes' when they are switched off and this can destroy transistors and ICs in the circuit. To prevent damage you must connect a protection diode …
