1pc PB1605BD 16MM yellow selfreset pushbutton switch with 3V light, round head Compact, easytouse momentary pushbutton with builtin visual feedback. The PB1605BD provides a tactile, selfreset (momentary) action and a yellow round head with an integrated 3V light so users get immediate status indication when the switch is activated. Key benefits Immediate visual feedback: the builtin 3V light clearly shows when the circuit is active, reducing guesswork during troubleshooting or operation. Momentary control: selfreset action returns the button to its normal position automatically, ideal for pulse, reset, or momentary start commands. Compact footprint: 16MM round head offers a lowprofile, neat appearance for panels, enclosures, and handheld devices. Singlepiece supply: sold as 1pc for repairs, prototypes, or small installations. Key attributes Model: PB1605BD Quantity: 1pc Size: 16MM (round head) Color: Yellow Action: Selfreset (momentary) Indicator: 3V light integrated Typical applications Hobby and prototype electronics: use as a momentary input with visible status for microcontroller projects, breadboard prototypes, and test rigs. Control panels and instrumentation: add a clear, compact push button for temporary commands (reset, test, or trigger) while the 3V light confirms activation. and replacement: suitable for replacing worn or nonfunctioning momentary pushbuttons where a yellow roundhead button with a 3V indicator is required. Practical notes The button is designed for momentary operation (selfreset). Use where a temporary contact is required rather than a maintained on/off state. The integrated 3V light requires an appropriate 3V supply or compatible driver to operate. Verify wiring and mounting dimensions before installation to ensure compatibility with your panel or enclosure. Simple, visible, and reliable—PB1605BD delivers momentary control combined with a clear 3V indicator in a 16MM yellow roundhead form factor.
