K1200 replacement button switch

2 days after finishing my watch, the button switch broke. I can’t find a part number, or dimensions and other specifications, to order a new switch to repair the watch. All smd switches with side button I can find have a different pinout, so brand and type number will be best.

Happened the same to me. Ordered this

Will update here after it arrives.

Arrived, replaced, works.
Actually I ordered it from over here (is the same button as in the initial link)

Broken original button and a replacement button

And for weird rules “new users can place only 1 image per post” here continued:
And after repair - fits perfectly and works OK.
