Push-And-Rotary OLED Knob

Well, this is me trying to design a rotary-and-push-button integrating a tiny china OLED module (0.49 in, 64x32 pixels). The OLED body (see image) must be detached from the PCB (it usually is attached to the PCB with double-sided tape) in order to be arranged on the knob like depicted.

The "body"-part is the non-moving part; intended to be fused with a chassis part later. Alternatively, one need to add some mounting facility if - for instance - mouting on a front plate is desired. The "knob"-part is the moving part (about 1 ... 2 mm travel).

**Warning**: This is by no means finished and I yet need an idea how to add contacts for the rotational input (left/right). So the actual switch-actuating part at the end is still missing. Any hint appreciated. Current vision is actuating one miniature switch with the vertical movement. And two wires on each side that get shorted by a "wing" during rotary movement (so no tactile "clic"-feedback here).

For assembly, a spring (made of piano
