Pull switches may be either two-position (open or closed) or multi-position (allowing for different fan speeds or levels of illumination). Mounted inside a pull switch, there could be two types of two-position toggle switches. (In both cases the stable physical open- or closed -situation would be switch in outer and string in upper position.)
