Rotary Encoders parrallel wiring?

Ken,

yes it would. You just have to use a DPDT (Double Pole Double Throw) switch since the Rotary Encoders have two signal wires.

Another idea:
One can use a relay which has a DPDT switch. Connect a motor (Those small ones found in toys) to each rotary . When you turn the Rotary, the motor generates a voltage. That voltage can in turn switch on a transistor. The transistor can switch the relay on to switch on the rotary it detects is the one rotating. Thus disabling the other one.

What a novel approach Fritz. I'm astounded at the ingenuity offered here.

Thanks Ken. Glad you liked the idea.

Here is another idea (Eric probably received his additional order of rotary encoders by now): I see it as a 3rd solution to this idea and we will probably see it in the future. Magnetic Rotary Encoders. A company by the name AustriaMicrosystems created a Magnetic Rotary Encoder. It is basically a magnet that rotates over an IC and the IC gives a 8 bit output of the position of the magnet. Since the magnet is not touching the IC, the lifespan of the encoder is larger than that of an optical or mechanic rotary encoder. It also measures the strength of the magnetic field, so this enable you to create an "Push-button" effect. One can probably use it for a pull effect as well. One can use your own magnet.

Now this is where it contributes to the parallel rotary encoder idea. The IC's can be daisy chained. I think that means you can have more than one encoder feeding data to the microcontroller. This could allow multiple encoders used for the same action.
