- Type: Choose lever-type, push-to-make, or hydraulic-actuated switches based on pedal placement and the braking system configuration.
- Activation Pressure: For hydraulic systems, note activation PSI (e.g., 45 PSI vs 95 PSI) to ensure timely brake-light signaling.
- Durability: Look for materials like solid metal bodies and corrosion-resistant terminals for long-term reliability.
- Ease of Installation: Prioritize models with simple mounting options and minimal wiring modifications when you’re DIY-ing.
- Vehicle Type: Classic cars may require OEM-style replacements; modern builds might benefit from universal or adaptable switches.
