Keep your dome light and door-ajar warning circuits switching properly with the Standard Ignition Door Jamb Switch DS-174. It drops in as a direct-fit replacement across a long run of classic Ford, Lincoln, and Mercury models, including the 1968-1979 Ford Thunderbird, 1970-1978 Ford LTD, 1970-1976 Ford Torino, 1970-1979 Lincoln Continental, 1968-1979 Mercury Cougar, and 1970-1978 Mercury Marquis — see the Buyer's Guide tab for the full list and engine details.

  • Copper alloy conductors: carry current with low resistive losses for solid electrical conductivity.
  • 100% tested: every switch is verified for both mechanical and electrical switching performance.
  • Robust build: a robust design and high-grade materials meet the demands of today's service professional.
  • OE pedigree: produced by a global manufacturer of ignition products with quality control from componentry to finished part.

Mounted in the door jamb, the switch senses whether the door is open or closed and signals the interior courtesy/dome lighting and door-open warning circuits accordingly. This unit is cataloged for front and rear door positions, including front-right and front-left applications. If a worn or corroded jamb switch is the reason your dome light stays on, won't come on, or your door-ajar warning acts up, this replaces it.
