Compact, reliable illuminated momentary pushbutton for clear operator control and visual status feedback. The PB1605BD combines a 16 mm round head with a builtin red 3V indicator light and a selfreset (momentary) action to simplify panel designs and small equipment interfaces. Key benefits Immediate visual feedback: integrated red 3V indicator light shows circuit status at a glance. Simple, spacesaving installation: 16 mm diameter fits standard 16 mm panel cutouts, ideal for compact control panels. Tactile, momentary control: selfreset action returns the button to its original position after release, reducing accidental mode changes. Singlepiece supply: sold as 1pc PB1605BD for easy replacement or upgrade. Key attributes Model: PB1605BD Size: 16 mm round head, designed for 16 mm panel mounting Action: selfreset (momentary) pushbutton Indicator: red builtin light rated for 3V operation Quantity: 1pc Form factor: round head, compact footprint suitable for tight panels and enclosures Construction: designed for regular user interaction and repeated switching (sturdy construction for general use) How it solves common problems Replaces nonilluminated buttons when visual confirmation is needed, reducing user errors. Adds a status indicator without extra LED modules, saving panel space and wiring complexity. Provides a dependable momentary control for start, reset, or input functions where a temporary contact is required. Typical applications Small control panels and instrumentation: use as a start/stop or reset button with visible status feedback. Hobbyist and electronics projects: ideal for microcontroller panels (Arduino, Raspberry Pi) where a 3V indicator is compatible. Equipment maintenance and replacement: direct swap for PB1605BDstyle panels needing an illuminated momentary pushbutton. Installation and usage tips Designed for 16 mm panel cutouts; secure mounting typically with a retaining nut or snapfit depending on panel design. Connect the indicator to a 3V supply or appropriate driver to power the red light. Use the switch contacts in lowvoltage control circuits or as specified by your equipment documentation. What you get One PB1605BD 16 mm selfreset pushbutton with integrated 3V red indicator light, round head design for comfortable operation and clear visual feedback.
