fischertechnik small push button switch

Human: A versatile control element for the [fischertechnik](https://www.fischertechnik.de/en) construction toy system, available in two versions: off/on and pole-reversing. The 8x8 mm push-button switch is sourced from a no-name item on ebay, believed to be the K8-8081D-L1 model manufactured by HRO. The off/on version requires minimal effort, as it needs no soldering. Simply cut off the middle contacts and bend the remaining four contacts flat, then insert the switch into the base part secured with a sleeve and a drop of super glue if necessary. The pole-reversing version demands some soldering skills, relying on the provided image for guidance. Be cautious when soldering to ensure correct orientation, as it only works in one specific way. For proper wiring, use two jacks diagonally opposite each other as input and the remaining two as output.
