A 16mm illuminated pushbutton with a built-in red LED and momentary action. The switch contacts connect only while the button is held down and return to their normally-open state when released — perfect for trigger inputs, action buttons, and interactive controls.

The LED is wired independently from the switch contacts, giving you full control over when the light is on. You can have it light up when pressed, when not pressed, or keep it always lit — whatever suits your project. The LED has a forward voltage of approximately 2.2V; connect a 220–1000Ω resistor in series when using a 3V or higher supply.

Key Features

• Momentary Action – Normally open; contacts connect only while pressed
• Built-In Red LED – Independently controlled from the switch for flexible indicator options
• 4 Contacts – Two for the switch, two for the LED (marked + and −)
