Mini Momentary Push Button Switch - 7mm Prewired SPST ON/Off Round Button for 3V-12V-24V Low Voltage Circuits, Model Railway, Arduino, DIY Projects & Industrial Control - 12PCS (Black)

Compact, Reliable Control for Your Low-Voltage ProjectsWhether 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 OperationWide 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 DesignEach 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 requiredQuick integration into your wiring harness or breadboardReduced risk of overheating or damaging the switch during assembly✅ Easy Panel MountingThe 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 AestheticSmall 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 ApplicationsModel 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.Technical Specifications:Type: Momentary Push Button SwitchCircuit: SPST (Single Pole, Single Throw)Contact Configuration: Normally Open (NO)Voltage Rating: 3V–24V DC / 230V AC (Max)Current Rating: 1ADimensions: 7mm diameter button, 10mm threaded lengthWire Leads: Approx. 4 inches (10 cm), red and black, pre-solderedMounting Hole Size: 7mm (panel thickness ≤ 2mm)Material: Plastic housing, metal threads, silver contactsPackage Includes:12 × Black 7mm Momentary Push Button Switches with Pre-attached Wires
