Abstract:
1. A start winding switch for an electric induction motor, the switch comprising: a terminal board comprising an electrically non-conductive material and having an edge margin; a first electrical contact mounted on the terminal board; a switch arm moveably connected to the terminal board for movement with respect to the board, the switch arm comprising a lever extending laterally beyond the edge margin of the board and an electrical arc barrier extending from the lever; and a second electrical contact connected to the switch arm; the switch arm and said second contact being moveable simultaneously relative to the terminal board and said first contact between an open position, in which an electrical resistance between the first and second contacts is relatively higher, and a closed position, in which the electrical resistance between the first and second contacts is relatively lower and the barrier is positioned adjacent the edge margin of the board and the second contact.
