Buying Guide
Key factors to consider when choosing a push button horn switch:
- Voltage and current: Most car/horn switches operate at 12V with 5A or 20A ratings. Choose a model that can handle your horn’s current draw to avoid switch failure.
- Mounting size: Typical 16mm (0.63 inches) mounting holes suit many aftermarket buttons. Verify hole size and clearance for your dash or bumper area.
- Illumination: LED indicators improve visibility at night. Decide between constant LED, LED-on-when-horn mode, or no illumination based on wiring complexity.
- Wiring and harness: Pre-wired units save installation time. Check wire length to ensure it reaches your power source and horn location without strain.
- Durability: Marine-grade or stainless steel buttons offer better corrosion resistance. Consider the environment—wet, salty, or dusty conditions may require tougher builds.
- OEM vs. aftermarket: OEM-style buttons resemble factory components and may fit better in some vehicles, while aftermarket designs can provide larger actuation or enhanced aesthetics.
