ABSTRACT:
A magnetically actuated float switch for turning on and off an electrical load device which includes a mounting member, a moveable bracket member which is attached to the mounting member and which is moveable between a first bracket position and a second bracket position by an external force. The moveable bracket member further has a first magnetic end and a second magnetic end which define a space therebetween. The first magnetic end and second magnetic end are oriented in a repelling arrangement. Insertion of a magnet in the space between the magnetic ends of the bracket results in the moveable bracket being moved from the first position to the second position. The moveable bracket member is operatively arranged to change the state of a switch between a first and second state. The switch is in turn operably arranged to change the state of an electrical load device between an on state and an off state.
