Brief DPDT relay component introduction – Double pole double throw

Table of Contents

Relays are mechanic switches that are switch electrically.

They are a cheap way to switch a high voltage/current load that would cost a lot more to switch with a semiconductor. They have mechanical wear and tear though.

Just a schematic of the relay component for this page. I’m not sure that there is a standard schematic diagram for relays. So I made this one based on some similar ones I seen. The schematics for relays that I come across tend to be drawn in a way that fits the rest of the circuit well, so they vary a bit.
