Momentary Push Button Switch – Black (SPST, 3A 250VAC)

This Black momentary push button switch is an easy, reliable way to add a press-to-activate input to your project. It’s a simple SPST, normally-open switch: press to turn something on, release to turn it off. Great for DIY electronics, test jigs, toys, small appliances, and control panels.

Why You’ll Like It

• Simple & dependable: OFF - (ON) momentary action for quick, temporary activation.
• Easy install: panel-mount design drops into a standard 16 mm mounting hole.
• Clear visibility: bold Black cap stands out on enclosures and control panels.
• Versatile rating: handles up to 3A at 250VAC for small mains-rated loads (or use with low-voltage DC control circuits).

Common Uses

• Momentary start/trigger buttons on DIY benches and control panels
• Reset or “test” inputs for Arduino/Raspberry Pi projects (via a low-voltage interface)
• Signal, buzzer, or light activation where a momentary SPST push button is ideal

Fit & Mounting

• Mounting hole: 16 mm (panel mount)
• Terminals: 2-pin quick-connect/solder lugs
• Cap color: Black

Tip: For low-voltage microcontroller use, wire this momentary push button to a digital input with a pull-up or pull-down resistor so a press cleanly registers as a logic change.
