1PC Blue 16MM Momentary Push Button Switch No lighting 2Pin R16503 is a compact momentary switch designed for simple and reliable input in electronic projects. It features a blue 16 mm body, twopin terminals, and no builtin lighting. The switch operates in a momentary fashion, returning to the off position when released. Supplied as a single piece, it is ready to install in a wide range of panels and enclosures. Key benefits Momentary action for precise control: press to activate a function, release to revert to the idle state, ideal for start, reset, or trigger inputs. Compact 16 mm footprint: fits in tight panel spaces and compact enclosures without sacrificing function. Distinct blue color: provides an easily identifiable actuator in assemblies and control panels. No lighting: no builtin LED, reducing power draw and avoiding unnecessary illumination in the panel.
