1PC 12mm red light metal button switch — illuminated, selflocking, round, compatible with 5V / 12V / 24V power supplies A compact, durable metal pushbutton switch that delivers clear visual status and reliable on/off operation. The illuminated red button provides instant feedback, while the selflocking (latching) mechanism keeps circuits firmly on or off without holding the button. Ideal for panelmounted control of lowvoltage DC systems. Key benefits Clear visual feedback: red light indicates ON state at a glance. Positive, reliable switching: selflocking latching action prevents accidental resets. Robust metal construction: durable for repeated use in workshops, cabinets, and panels. Compact footprint: 12mm round size fits small control panels and tight spaces. Multivoltage compatibility: available for common DC supply voltages (5V, 12V, 24V). Single unit: supplied as 1PC for direct replacement or builds. Key attributes Functionality: illuminated pushbutton switch with selflocking (latching) action. Compatibility: designed for 5V, 12V, or 24V DC power supplies. Size: 12mm round (compact panel footprint). Material: metal button and housing for enhanced durability. Indicator: red light built into the button for clear ON indication. Quantity: 1PC included. Typical applications DIY electronics and maker projects: control power to Raspberry Pi, Arduino, or custom circuits using 5V, 12V, or 24V supplies. Lighting and lowvoltage power control: switch LED strips, small transformers, or portable power modules with clear on/off indication. Panel and automotive installations: compact, durable control for 12V vehicle accessories or 24V equipment panels. Installation notes Intended for panel mounting in a 12mm round location; wire to the matching DC supply voltage (5V, 12V, or 24V) as required. Confirm the switch voltage version before wiring to ensure correct illumination and operation. Supplied as a single unit (1PC) for direct use or replacement. This 12mm red light metal button switch offers a straightforward, dependable solution for adding illuminated, latching on/off control to compact panels and lowvoltage systems.
