Abstract
The present invention relates to an electrical switch including an arcuate cavity partially filled with an electrically conducting fluid. The fluid is adapted to move into electrical contact with a pair of electrodes positioned within the cavity in response to a rotational force acting thereupon. The switch is electrically connectable to a rotatable platter. When connected to the platter, the switch is positioned radially outward from the platter's axis of rotation, such that the forces generated by the platter upon rotation urge the electrically conducting fluid into contact with the electrodes and thus complete a circuit.
