Toggle switch caps are a type of cap that protects the tip of a lever of a toggle switch. A toggle switch is an electric switch operated by means of a projecting lever that is moved up and down.
A toggle switch is a class of electrical switch operated by hand with a mechanical lever, handle, or rocking mechanism. A toggle switch is typically any type of switch with a handle that allows a circuit to be energised and de-energised. The devices include everything from very large switches, often provided with two toggles joined by a linking bar, to very small switches, many of which can be found on a single switchboard.
Toggle switch covers act as a protector for the switch. Some toggle switch covers will automatically turn the switch off when flipped closed, while others protect the toggle switch by preventing it from being turned on.
