  • Magnetic lid switch
    Patent number: 7536880
    Abstract: A magnetic lid switch assembly includes a first magnetically actuated electrical switch that has a lever arm movable between a first position wherein the first switch is open and a second position wherein the first switch is closed. A second magnetically actuated electrical switch electrically is connected in series with the first switch. The second switch has a lever arm movable between a first position wherein the second switch is open and a second position wherein the second switch is closed. A first actuator is magnetically coupled to the first switch.
