12V metal push button switch with momentary on/off action Purpose: Provides a reliable push-to-activate (momentary) on/off control for 12V electrical systems. Ideal for short, repeatable operations where the circuit should only be energized while the button is pressed. Key benefits: Quick response: Momentary action delivers immediate control for functions that require brief activation. Compact installation: 16 mm diameter keeps the switch small and easy to place in crowded panels or equipment. Durable conductivity: Brass construction offers good electrical conductivity and long-term mechanical durability for stable performance. Versatile control: Designed for use as a horn switch and for relay control, enabling direct activation of audible signals or indirect switching of higher-current circuits via a relay. Simple integration: Fits common small-device applications and 12V systems used in vehicles and light equipment. Important attributes Function: Momentary on/off push button for short-duration control. Voltage: 12V operation, suitable for 12V electrical systems. Size: 16 mm diameter for a compact footprint. Material: Brass construction for reliable conductivity and durability. Performance: Stable, repeatable switching suitable for frequent use. Practical use scenarios Vehicle horn control: Install as a horn switch on cars, motorcycles, ATVs, or other 12V vehicles to provide immediate, momentary activation of the horn circuit. Relay control for accessories: Use the switch to trigger a relay that controls lights, horns, or other accessories, keeping high current away from the switch itself and extending component life. Small equipment control: Mount on control panels for 12V-powered equipment or DIY projects where compact, durable momentary switching is required. What this solves Prevents accidental continuous activation by using momentary action instead of latching switches. Reduces wear on low-current switch contacts by allowing relay-driven switching for high-current loads. Saves panel space and simplifies installation with a compact 16 mm form factor. Installation and compatibility tips Designed for 12V systems; confirm compatibility with your vehicle or device wiring before installation. Compact 16 mm diameter makes it suitable for small panels and enclosures where space is limited. Use the switch to directly control low-current circuits or to drive a relay for higher-current loads.
