Compact, illuminated momentary control that gives clear visual feedback and reliable tactile action. The PB1605BD is a 16MM green selfreset (momentary) pushbutton switch with a builtin 3V indicator light and a round head — ideal for compact panels, DIY electronics, and equipment where space and clear status indication matter. Key features Model: PB1605BD Quantity: 1pc Size: 16MM round head Color: green Operation: selfreset (momentary) pushbutton Illumination: integrated 3V light Why you need it Instant visual status: the builtin green 3V light provides immediate feedback so users can see when a circuit is active. Spacesaving form factor: the 16MM round head keeps the switch compact and unobtrusive while remaining easy to press. Reliable momentary action: selfreset operation prevents accidental latching, making it suitable for momentary commands like reset, start, or input triggers. What makes it useful Simple replacement or upgrade for existing 16MM switch openings that require a green illuminated momentary button. A single integrated unit that combines switching and indication without additional separate LEDs or indicators. Clean, roundhead appearance that fits professional and hobby projects alike. Typical applications Control panels and equipment interfaces where a momentary control and visual indicator are required. Prototyping and hobby electronics (microcontroller projects, breadboard/PCB implementations) that use a 3V indicator. Small appliances or instruments that need a compact illuminated pushbutton for user input or status signaling. Installation and compatibility notes Designed for systems that provide a 3V supply for the builtin indicator. Verify your circuit's voltage before connecting. Compact 16MM size suits panels and enclosures that accept 16MM round pushbutton components. Onepiece supply: 1pc included. Simple, compact, and illuminated — the PB1605BD delivers reliable momentary switching with clear green visual feedback for a wide range of control and prototype applications.
