This might sound like an odd question, but how does a signal/indicator stalk know when to snap back into the neutral (not signalling) position after a user turns the wheel? I’ve never had the chance to take apart an indicator light or a steering column, and part of me is really curious to know how the mechanism works.

I wonder - is the degrees of rotation that a driver has to turn the wheel back before the light snaps off the same between different manufacturers?

I’ve been thinking about this while commuting home for more days than I’d care to admit.
