A latching circuit breaker is provided that is small and switches with a small amount of current. A battery switch incorporating the circuit breaker mounts on a battery top and is easily added as an accessory to control all of a battery\s power. A convenient battery protection device uses the battery switch and a control system to automatically control a battery, prevent overdischarge, and reserve starting power. A manually resetting battery protection device is also provided. The battery protection device is adaptable to be incorporated into the design of a battery resulting in a trouble free, long-life battery.

A circuit breaker for switching an external electrical circuit means having a current path comprising: a frame; an armature mounted relative to said frame and having an edge, said armature being movable for moving said edge between a first position and a second position spaced from said first position; first means selectively operable for moving said armature edge from said first position to said second position; a pair of electrical circuit contacts mounted adjacent to said edge of said armature and connectable to the external electrical circuit, said pair of contacts including a fixed-position contact and a movable contact, said movable contact being movable between contacting and noncontacting positions for opening and closing the external current path; roller means having a radius of curvature is mounted on said armature edge; means defining a roll surface for said roller means to roll along when said armature edge moves between said first and second positions, said roll surface including a movable surface that moves relative to said fixed-position contact a distance less than the radius of said roller means as said roller means rolls along said roll surface, with said contacts moving between said contacting position and said noncontacting position when said roller means rolls relative to said movable surface.
