16mm Yellow Momentary Pushbutton

This illuminated pushbutton combines a momentary switch with a separate yellow LED in a black plastic housing. It is suited for hobbyists, students and engineers adding a tactile input with visual feedback to breadboard or panel-mount projects. The LED operates independently so it can show status, act as a locator light or simply add style.

Simple panel mount with separate LED wiring

The 16mm threaded body fits a standard panel cut-out and secures with the included nut. Four terminals underneath — two for the normally-open switch and two marked + and – for the LED — keep circuits independent. A 220 to 1000 ohm series resistor is required for the 3V forward-voltage LED; omitting it will burn out the emitter. Solder tags are small so use fine tip and minimal heat.

Momentary action with independent 3V yellow LED

The switch closes only while pressed and opens immediately on release, making it ideal for momentary triggers such as reset, mode select or user input. Because the LED is electrically isolated, the same button can signal power-on, confirm a press or stay dark until software decides. Choose this part when you need a single 16mm momentary control with a separately driven yellow indicator.

Questions about this item

How can I verify the yellow LED illuminates correctly after wiring the 16mm pushbutton?

Apply 3 V or higher through a 220 to 1000 ohm resistor to the marked + and – LED contacts; the yellow LED should light independently of the switch action.

What components are included with the illuminated pushbutton and what must be sourced separately?

The button ships with black plastic housing, integrated yellow LED, and four contacts (two for switch, two for LED); a 220–1000 ohm current-limiting resistor and a 3 V+ power supply are not included.

Which version of the 16mm illuminated pushbutton should I choose for a momentary, normally-open switch with separate LED control?

This model is momentary, normally open, with a yellow LED that can be driven independently — select it when you need momentary actuation and separate LED indication.
