This switch is intended for those who understand or want to know the difference between two wires going to a polarized plug. The wire leading to an open is usually one with a seal leading to a hot or live contact. It's tight but my arms are clumsy so you can handle it. Strip the wires, twist them and insert them into the interlock switch terminals. For those who have used other switches, do not remove the hot lead wire segment as some other switches require.
