1. A disconnect switch comprising:
- at least one conductor pin moveable between a conducting position and a non-conducting position;
at least one spring in operable relationship with said at least one conductor pin for biasing said at least one conductor pin toward said non-conducting position;
a locking mechanism for holding said at least one conductor pin in said conducting position against said bias of said at least one spring; and
a surging mechanism for moving said at least one conductor pin to said conducting position, said surging mechanism including;
a handle;
a gear coupled to said handle; and
a rack meshingly engaging said gear, said rack being operably secured to said at least one conductor pin.

Abstract
A battery disconnect switch is provided for breaking the conductive path in an electric vehicle comprising at least one conductor pin moveable between a conducting position and a non-conducting position. At least one spring is provided for biasing the conductor pin toward the non-conducting position. A surging mechanism moves the conductor pin to the conducting position and a locking mechanism holds the conductor pin in the conducting position against the bias of the spring. A release mechanism releases the locking mechanism allowing the bias of the spring to force the conductor pin to its non-conducting position.

9. A battery disconnect switch for breaking the conductive path of high current in an electric vehicle comprising:
-
a housing; a top removably secured to said housing; a handle rotatable between an on position and an off position secured to said housing; a lockout flange extending from said handle; a lockout device removably connected to said flange for preventing said handle from rotating; an overcenter spring mechanism coupled to said handle for biasing said handle towards said first position when said handle is in said first position and operable for biasing said handle towards said second position when said handle is in said second position; a power connector secured to said housing; a positive conductor pin extending from an interior of said housing into said power connector; a negative conductor pin extending from an interior of said housing into said power connector; a gear coupled to said handle such that rotation of said handle rotates said gear; a rack meshingly engaging said gear such that rotation of said gear translates said rack; a latch removably engaging a notch in said rack; a cam coupled to said handle, said cam being operable for removing said latch from said notch; a first stationary plate disposed opposite a second stationary plate supporting a plurality of guide posts therebetween; a plurality of springs concentrically disposed about said guide pins; a moveable plate slidingly mounted on said guide pins, said moveable plate being secured to said rack; said plurality of springs exerting a force on said moveable plate and on said second stationary plate; an insulator mount secured to said moveable plate, said insulator mount being secured to said positive conductor pin and said negative conductor pin; and an insulator assembly having a plurality of insulators horizontally disposed therein adjacent said second stationary plate receiving said positive conductor pin and said negative conductor pin therethrough. - View Dependent Claims (10, 11, 12)

15. A disconnect switch comprising:
-
at least one conductor pin moveable between a conducting position and a non-conducting position; at least one spring in operable relationship with said at least one conductor pin for biasing said at least one conductor pin toward said non-conducting position; a locking mechanism for holding said at least one conductor pin in said conducting position against said bias of said at least one spring; a handle rotatable between a first position and a second position; a gear coupled to said handle such that rotation of said handle rotates said gear; a rack meshingly engaging said gear such that rotation of said gear translates said rack; a first stationary plate disposed opposite a second stationary plate supporting a plurality of guide posts therebetween; a plurality of springs concentrically disposed about said guide pins; a moveable plate slidingly engaging said guide pins, said moveable plate being secured to said rack; said plurality of springs exerting a force on said moveable plate and on said second stationary plate; an insulator mount secured to said moveable plate, said insulator mount being secured to said at least one conductor pin; a latch removably engaging a notch in said rack; and a cam coupled to said handle, said cam being operable for removing said latch from said notch. - View Dependent Claims (16, 17)
