ABSTRACT:
Electrical multi-circuit switch apparatus includes a flat flux plate and a pyramid-shaped magnet having a base and three or more triangular faces defining intersecting edges, outer edges and an apex. The flux plate is fixed in a molded base in a depression with substantially vertical walls and electrical terminals having portions on said walls. The magnet carries spring arm contacts on its outer edges and is free to rotate, with respect to the flux plate, about whichever intersecting edge contacts the flux plate between stable positions in each of which one of said faces abuts the flux plate for maximum magnetic attraction. The movement is initiated by a downward force at a predetermined location on the base of the magnet and occurs with a magnetic snap action, moving said spring arm contacts in a vertical rocking motion to change the electrical connections between said terminals in a predetermined manner. The apparatus is shown in an automotive exterior lamp control.
