Push-And-Rotary OLED Knob

thingiverse

I'm attempting to design a rotary-and-push-button assembly that integrates a tiny China OLED module (0.49 inches, 64x32 pixels). The OLED body must be detached from the PCB in order to be arranged on the knob like depicted. The "body" part is non-moving and intended to be fused with a chassis part later, or mounting facilities can be added if desired. The "knob" part is moving (about 1-2 mm travel) and needs to be connected to the rotational input (left/right). I'm still seeking an idea for how to add contacts for this purpose. The current vision is to actuate a miniature switch with vertical movement, and two wires on each side that get shorted by a "wing" during rotary movement. For assembly, a spring needs to be added made of piano wire or similar material, and two telescoping aluminum tubes (10/8 mm outer/inner diameter and 12/10 mm) need to be glued in the "knob" and "body" parts. The "end cap" and "knob" also need to be glued together, housing the spring. I plan to cover the OLED module with an additional disc made from tinted PMMA and a printed cap over the whole "knob"-assembly.
