Datsun 240Z Turn Signal Switch (1971)

If you suspect your turn signal switch is bad, you might consider to (carefully) disassemble and clean it.  The full current for the turn signal lamps goes through this switch, so over 40+ years, the switch contacts take a beating.  This is a simple and effective project, however, patience is required.

  All the component-parts. This switch is opened by carefully opening the three 'tabs' on the switch body.

  Here is how the contacts look magnified 20x. Clear pitting and burning is seen.
