How Relays Work | And Why They Still Beat TRS Relays are a simple way to use one electrical circuit to control another, and they’re still widely used despite the rise of transistors and solid-state switches. In this video, we break down: •\tHow relays work and what happens inside them •\tThe coil, armature, spring, and contacts •\tHow a low-power signal can control a much larger load •\tFlyback voltage and other problems like contact bounce and arcing •\tHow to read relay ratings and choose the
