Unless you have two switches for the same light so the on position depends on what position the other switch is in too

  Both switches should be turned 90 degrees and move horizontally.

  Yup I've got some like these in the house here.

  luckily all light switches have a light indicator show the current status.

    Except when the bulb has gone. Which is the one time you really want to be sure the power is off.
    • gpderetta 4y ago
      In that case removing the broken bulb and sticking your fingers on the metal bits also works.
