WTB Jogdial ..?

[m1tch37]

Greetings,

I want to buy a component i can only describe as a jog dial. I cannot find them in stores anywhere, but have seen them on countless applications. You often see them as volume dials on radios. They are like potentiometer that can spin forever. I assume how they work is each 'jog' a line goes temporarily high (one for each direction), i dont know how you would handle a fast twist in this case, but i will work that out later. Ideally i would also like the dial to be pushable (on my radio, this turns it on/off) but that may be not available.

Does anyone know where i could find such a component?

Cheers
Mitch

It's called a 'quadrature encoder', the micro-controller that you connect it to requires software writing for it to decide which way it's turning, and to count the pulses.

Thats great thanks. They seam to be widely available, i was just searching under the wrong name.

But i was wondering if anyone knew if you can purchase one that can be pushed in as a switch too.

Edit: Spoke too soon, i found this:

Does this look ok for what i need?

That looks like what you want but it's a bit expensive.
