These push buttons from Mentor have a short-travel button function which permits a very compact design. Either a transparent or black cap may be used. The transparent cap is designed to provide internal labelling which can be inserted from the outside. https://elecena.pl/product/27736516/mentor-1852-6231-fel-push-button-tht-vertical 2025-01-22 https://elecena.pl/product/27736516/mentor-1852-6231-fel-push-button-tht-vertical 2025-07-16
