Maiming hardware so you don’t have to!
Ever wondered how the insides of a cheap rotary encoder look? Yeah, probably not, but I did, so here they are:
(all photos are in extra big size)
The small teeth on the underside of the contactor wheel, are the detents of the enoder. They engage a flat copper spring on the aluminium body. (see next photo) The exterior teeth do nothing in ths particular one.
The bottom body is the pushbutton housing, and it’s just like a big pushbutton that also serves as the spring for the shaft.
I love the modularity of the thing, with all the blue engaging parts, unfortunately, you can’t connect two similar ones to do something weird like nested encoders. (don’t ask the purpose, I just like to wonder about things…)
Oh, Mr.G gave out something wonderful! Look at this!
There also seem to exist dual encoders out there…cool!
