1PC Yellow 16MM Momentary Push Button Switch No lighting 2Pin R16503 A compact, easytouse momentary push button switch designed for projects and control panels that need a simple pushtoactuate control. The bright yellow actuator provides clear visual identification while the nonilluminated design keeps wiring and installation straightforward. Key attributes Model: R16503 Quantity: 1PC Color: Yellow Size: 16MM Action: Momentary (pushtomake; contact closes only while pressed) Lighting: No lighting / nonilluminated Terminals: 2Pin Why customers choose this switch Simple, dependable momentary action that is easy to understand and use. Clear visual button color for quick identification in panels or projects. Minimal wiring: twopin design reduces complexity for basic on/off or trigger functions. Compact 16MM form factor that works well where space is limited. What this switch solves Provides a reliable, tactile way to send a momentary signal — ideal for reset, start, test, or trigger actions. Eliminates the need for illuminated switches when indication is not required, reducing parts and wiring. Offers a straightforward hardware solution for hobbyists, technicians, and engineers who need a basic pushbutton control. Performance and compatibility notes Momentary operation: the circuit is completed only while the button is pressed; it returns to open when released. Twopin terminal arrangement for simple connection to a circuit or control input. Neutral, nonilluminated design avoids additional power or wiring requirements associated with illuminated switches. Typical use cases DIY electronics and prototyping: use as a test trigger, input for microcontroller projects, or manual sensor reset. Control panels and equipment: serve as a start, stop, or reset button where a momentary action is required. Small appliances and devices: offer a simple manual input for triggering functions without indicator lighting. Installation and handling tips Wire to the two terminals according to your circuit needs; ensure the circuit is deenergized during installation. Verify mechanical fit and mounting requirements in your application prior to final installation. This 1PC Yellow 16MM Momentary Push Button Switch No lighting 2Pin R16503 provides a straightforward, reliable solution for any application requiring a compact, nonilluminated momentary push button.
