  • a base member having at least one recess formed therein which is partially defined by a peripheral wall thereof;

    at least one switch disposed within the peripheral wall of the base member; and

    at least one trigger ball disposed within the recess and freely movable about the peripheral wall of the base member;

    the sensor being operative to generate at least two different states corresponding to respective positions of the sensor relative to a reference plane, the movement of the sensor relative to the reference plane facilitating the movement of the trigger ball within the recess, with one state being generated when the trigger ball is in contact with the switch and another state being generated when the trigger ball is not in contact with the switch.
