Abstract: A power disconnect switch having a generally parallelepiped base with first and second electrical conductors mounted thereon. A switch piece pivots on one of the electrical conductors to connect to the other electrical conductor. The switch piece has an insulated handle, and a projection extends from the handle. The projection has a shape which allows it to fit snugly into a holder tool, and this allows an operator to open the switch without danger of electrocution. An angled insulating plate which fits next to the parallelepiped base has a side portion which insulates the switch from adjacent switches, and a bottom portion which insulates screws in the parallelepiped base from a metal panel, shelf, or box, on which the switch may be mounted.
