Inside a car clock-spring module (steering wheel wiring interface)

This module was sent by George of Junk From Work:-

At first I thought it was just a clock spring module from a steering wheel, but it does contain wheel movement sensing circuitry.

A clock spring mechanism is used to transfer power and signals for things like controls, the horn and airbag from the vehicle to the steering wheel. That means it has to deal with multiple rotations. I always wondered what was inside them.

The fact I even knew what this thing was called or the method of operation is largely due to the subliminal education I've received while relaxing with Eric O's channel - South Main Auto:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
