Compact, reliable momentary pushbutton with integrated 3V indicator light — ideal for adding a clear visual status and a tactile control to panels and small electronic projects. Key benefits Visual feedback: builtin 3V light gives immediate indication when the switch is active, reducing user error and improving usability. Compact panelfriendly size: 16MM body and round head provide a clean, professional finish on control panels and enclosures. Simple momentary action: selfreset (momentary) operation returns to the off position automatically after release, ideal for short control inputs and reset functions. Easy to integrate: straightforward panelmount styling makes it quick to fit into 16mm cutouts and wire into 3V circuits. What it is Model: PB1605BD Quantity: 1pc Size: 16MM (panelmount) Head: round Color: blue Action: selfreset (momentary) pushbutton Light: integrated 3V indicator light Key attributes Functionality: momentary pushbutton with visual indication. Compatibility: suited for circuits and projects using a 3V indicator supply; fits standard 16MM panel cutouts. Form factor: round head for comfortable pressing and a neat appearance on panels. Performance: consistent selfreset action for repeated, reliable operation. Typical applications DIY electronics and maker projects where a compact, illuminated momentary switch is needed (Arduino, Raspberry Pi and microcontroller panels). Control panels or instrument frontends that require a small, easytoread status indicator and a momentary input (reset, test, or trigger buttons). Batterypowered devices and portable equipment that use a 3V supply and benefit from an integrated illuminated control. What's included One (1) PB1605BD 16MM blue selfreset pushbutton switch with 3V light, round head. Notes for installation and use Designed for mounting in a 16MM panel hole; verify panel thickness and hole dimensions before installation. The integrated light is specified at 3V; supply the appropriate voltage and wiring according to your circuit requirements. Confirm wiring and polarity (if applicable) in your application before powering the circuit. A straightforward, panelready momentary switch with integrated illumination for clear status indication and reliable shortcycle control.
