An electric pull switch is attached to a toggle type switch: one pull to switch on and next pull to switch off.
The most common use of a pull switch is to operate a ceiling electric light. The ceiling fanand mechanical wall fans are also appliances often operated by pull switches. 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.) One type would switch to closed (alternatively open) already during the initial pull in the string. The other type would switch to closed (or open) only when releasing after a full pull. With the first type, the weight of the string and handle could accidentally switch the load intermittently on and off, when still around the initial position (depending on the internal spring). This could potentially increase the danger of overheating in the switch.In a damp environment, electrical pull switches have a safety advantage because the user is separated from the electricity by a significant distance and if the lead is made of an electrically insulating material, such as cotton string.
