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 an electric light. The ceiling fan is another appliance often operated by pull switches. Pull switches may be either two position (open and closed) or multi-position (allowing for different fan speeds or levels of illumination).
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.
Most commercially available pull switches use a short length of ball chain, which may then be connected to any number of optional leads for added length or decoration. Leads for decoration or utility are usually made of metal or plastic. They can come in many different shapes ranging from animals, geometric shapes, or look just like a weight.
