87MJTIM Posted 13 hours ago Share Posted 13 hours ago Does anyone know the name of or part number for the gravity activation switch in the light box? I have a light that is in decent shape and want to get it working. I can get continuity before the switch and after the switch. The switch is supposed to make contact when the box is tilted up.

eaglescout526 Posted 12 hours ago Share Posted 12 hours ago Isnt that a mercury switch? I know Fords of the same era have the same kind of lamp assembly. Maybe GM ones have the same part as well? Link to comment Share on other sites More sharing options...
87MJTIM Posted 12 hours ago Author Share Posted 12 hours ago Mercury switch. That’s the name. Are there aftermarket options rather than searching through JYs? Link to comment Share on other sites More sharing options...

eaglescout526 Posted 11 hours ago Share Posted 11 hours ago I have no idea on the aftermarket of those. I’d imagine it’s tough since mercury is toxic. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted 1 hour ago Share Posted 1 hour ago Why not use an alarm tilt sensor? Very simple normally open contact that closes when tilted past a preset point. They are used in car alarms to deter theft by tow truck Link to comment Share on other sites More sharing options...
