1PC 12mm Flat Metal Button Switch — White Illumination, SelfLocking (Latching), Round — Compatible with 5V / 12V / 24V Why this switch solves your problem Simple, visible on/off control: the builtin white LED provides immediate visual feedback so you always know whether a circuit is powered. Reliable latching action: the selflocking (latching) mechanism stays in the selected position without needing continuous pressure, making it ideal for power on/off control. Spaceefficient and durable: the compact 12mm round form and metal construction fit tight panels and stand up to repeated use. Key features at a glance Quantity: 1 piece Mounting diameter: 12mm (round, flat design) Illumination: white light (builtin LED) Action: selflocking / latching push button Construction: metal button and bezel for durability and a clean appearance Voltage compatibility: LED rated for 5V, 12V, or 24V systems (select or wire accordingly) What you get A compact, flat metal push button that combines a rugged feel with clear white illumination and a latching on/off action. It is designed for simple panel installation and provides a professional look on small control panels or enclosures. Practical compatibility and usage notes Designed to be used with 5V, 12V or 24V power systems for the LED illumination. Confirm wiring for the correct supply voltage to avoid under or overdriving the LED. Typical mounting: panel cutout for 12mm round switches; ideal where space is limited and a flat, lowprofile button is preferred. Intended as an illuminated power/control switch; please wire according to your application's power/control circuit requirements. Example applications Small power supplies and bench equipment: present a clear, illuminated poweron indicator and reliable latching control for lab or hobby power modules. DIY electronics and control panels: mount in instrument enclosures, Raspberry Pi/Arduino projects, or custom automation panels that need a compact, durable illuminated switch. Automotive and 12V systems: use as a visible on/off switch for invehicle accessories or auxiliary circuits (wire the LED to the appropriate voltage). Why customers choose this switch Compact 12mm size that fits tight panel spaces Metal construction for a polished, longlasting finish White LED provides clear status indication Selflocking (latching) action for dependable on/off control Simple compatibility across common voltages (5V / 12V / 24V) Installation tips Confirm the panel cutout size (12mm) before installation. Match LED wiring to your chosen supply voltage (5V, 12V, or 24V). Ensure proper electrical connections for the switching contacts and LED leads to fit your circuit design. Note: Product is sold as a single piece (1PC). Follow standard safety and wiring practices when integrating this switch into powered circuits.
