Thinking this switch may be useful for one of my future projects, I searched further on the internet.
Is this the switch? ALPS RKJXT1F42001.
The circuit diagrams on that page may help you in debugging the circuit.

Hi Semaj4712,
Did you perhaps measure the encoder pins to see what is happening? A scope is very useful to see the voltages and timing relation between those pins.
With respect to the external pullups; the encoder...
Hi Semaj4712,
When I looked at the product webpage you linked to, I saw that the pinout in silkscreen on the shown switch differs from the switch pinout that you showed in the diagram.
Look at the position of the...
@ Theremingenieur: thanks, this is by far the best way to read those cheap 75 cent encoders! Running a T3.2 @ 96MHz never gave a wrong readout.
It took me a while to figure out what you did in that class, but...
