1PC 12mm Flat Green Light Metal Button Switch — SelfLocking, Round — Compatible with 5V / 12V / 24V Why choose this switch Simple, reliable on/off control with a builtin green indicator that clearly shows power status. Durable metal construction provides a solid tactile feel and longterm mechanical stability compared to plastic buttons. Selflocking (latching) action eliminates the need for external relays or special wiring to maintain power state. Key features Quantity: 1PC Diameter: 12mm (round, flat ) Illumination: green light for clear visual feedback Material: metal button housing and bezel Action: selflocking (latching) power switch — press once to latch ON, press again to release/OFF Voltage compatibility: usable with 5V, 12V, and 24V power systems Functionality and compatibility Works as a primary power switch or status indicator in lowvoltage DC systems. The illuminated makes it easy to verify whether a circuit is energized. Compatible with common electronics projects and systems that use 5V, 12V, or 24V supplies. Ideal where a compact, round, panelmounted switch is required. Flat, lowprofile design fits modern equipment aesthetics while providing a positive on/off action. Practical use cases DIY electronics and singleboard computer projects (for example, a simple on/off switch and power indicator for 5V Raspberry Pi setups). Automotive or marine accessories and 12V DC equipment where a durable metal switch and clear status light are needed. Small control panels, lighting circuits, and 24V industrial or HVAC control lines that require a latching power switch with visible indication. What this switch solves Replaces bulky, nonindicating switches with a compact, integrated solution that both controls power and indicates state. Prevents ambiguity over system status with a builtin green LED, reducing troubleshooting time. Provides a robust mechanical interface that is less likely to wear out or feel loose compared to lowerquality plastic buttons. Simple installation tips Designed for panelstyle mounting in a 12mm hole (verify hole size before fitting). Ensure the switch wiring matches your system voltage (5V, 12V, or 24V) for the illumination circuit. Confirm wiring and polarity where applicable before applying power. This 12mm flat green light metal button switch delivers a compact, durable, and easytoread solution for controlling and monitoring 5V, 12V, and 24V power circuits. One piece included.
