Mercury Turn Signal Switch allows drivers to announce lane changes immediately and remain strong in everyday conditions. The foundation of Mercury was midsize cars with comfortable suspension, no-noise cabins, and styling that was easy to notice and remember starting in the late 1930s and running through Cougars, Grand Marquis, and any number of showroom makeovers that were willing to add just enough to keep passengers comfortable, the steering light, and the road noise gone even as tastes changed and chrome gave way to plastic, the long hood to hatchback, and the dashboards were laid out to have the key items visible at a glance, so it kept passengers comfortable. The Turn Signal Switch is mounted in the steering column, and it is a tactile switch which, in any surviving Mercury, connects fingertip action to flashing lamp via very strong contacts and spring resistant to the wear of thousands of clicks, ensuring that there is no confusion between the car and its traffic. A new Turn Signal Switch when the original one becomes sticky or loses a connection, the new one gets the desired click-off action back that Mercury drivers are applied to, instead of guesswork on the part of tailgaters, and the danger of unexpected merges is cut by half. Due to the heavy plastics and copper path applied in the Turn Signal Switch, Mercury owners can be assured of reliable signaling even after other gadgets have died.
