Application Details

This ignition switch is used in push-button start systems where the dashboard-mounted switch sends the start signal to the vehicle’s electrical system. Standard Ignition US-1049 matches the listed Infiniti applications, including the 2014-2018 Infiniti Q70, 2011 Infiniti FX50, 2010 Infiniti EX35, and 2010 Infiniti FX35. It cross-references CS1409 for the same application.

Common Issues It Can Address

  • Intermittent or no-start condition from a worn push-to-start switch
  • Button response problems when the original switch no longer registers input
  • Electrical connection faults at the dash-mounted ignition switch
  • Cracked, damaged, or loose switch housing at the column mount
  • Replacement need after connector or terminal wear in the start circuit

Installation Notes

Verify the connector shape, terminal count, and mounting location before installation. This unit uses a snap-fit design and a square female connector, so the vehicle-side plug and dash opening must match the original configuration. Confirm the Infiniti Q70, FX50, EX35, or FX35 application by year and dash-mounted layout before replacing the switch.

Quality Assurance

Standard Ignition supplies electrical replacement parts for vehicle-specific applications, and US-1049 is built to match the listed connector and mounting requirements for the confirmed Infiniti fitments.
