Compact, Reliable Control for Your Low-Voltage Projects
Whether you're building a model railway, wiring a custom automotive panel, or creating an interactive electronic project, these 7mm prewired momentary push buttons offer a simple, reliable way to add manual control. With a broad voltage range and a clean, minimalist design, they're a versatile component that fits seamlessly into both hobbyist and light industrial applications.
Key Features & Benefits:
✅ Broad Compatibility & Safe Operation
Wide Voltage Range: Works with common low-voltage DC systems (3V, 5V, 12V, 24V) and can handle up to 230V AC at 1A.
SPST Momentary Action: The switch is “ON” only while pressed—perfect for triggering a short action (like a buzzer, LED, or relay) without needing a separate “off” operation.
Normally Open (NO) Contacts: Circuit is open at rest; closes only when the button is pressed.
✅ Ready-to-Use Prewired Design
Each switch comes with two flexible, color-coded wires (red for positive/common, black for load) already soldered to the terminals. This means:
No specialized soldering skills required
Quick integration into your wiring harness or breadboard
Reduced risk of overheating or damaging the switch during assembly
✅ Easy Panel Mounting
The switch body includes a threaded barrel and a hex nut, allowing you to securely mount it in a pre-drilled 7mm hole (panel thickness up to 2mm). Installation is straightforward: insert from the front, tighten the nut from the back.
✅ Compact & Discreet Aesthetic
Small Footprint: Just 7mm in diameter, ideal for space-constrained control panels or miniature models.
Clean Black Finish: Low-profile appearance that blends into dashboards, enclosures, or DIY projects.
Tactile Feedback: Provides a clear, satisfying click when pressed.
✅ Wide Range of Applications
Model Railroads & RC Systems: Control signals, lights, or sound modules.
Electronics Prototyping: Arduino, Raspberry Pi, breadboard circuits, and custom controllers.
Automotive & Marine: Dashboard switches for auxiliary lights, fans, or accessories.
Industrial & Commercial: Low-voltage control panels, machine start/stop triggers, safety interlocks.
Home DIY: Custom doorbells, game controllers, or interactive art installations.
