The present invention provides a rotating dual switching mechanism comprising: a first switch having an activator movable between an "on" state and an "off" state, said activator being located on a rotation axis; a second switch having an activator also movable between an "on" state and an "off" state, said activator being offset from said rotation axis; a ring-shaped actuator concentric with said rotation axis and movable between a first position operable to put the activator of said second switch in the "off" state thereof and a second position operable to put the activator of said second switch in the "on" state thereof; and a switch arm having a first portion for changing the state of the activator of said first switch and a second portion for moving the ring-shaped actuator between the first and second positions thereof, said switch arm being rotatable about the rotation axis. In a first aspect of the invention, the switch arm may be movable between a first position operable to put the activator of the first switch in the "of" state thereof and the ring-shaped actuator in the first position thereof, a second position operable to put the activator of the first switch in the "on" state thereof and the ring-shaped actuator in the first position thereof, and a third position operable to put the activator of the first switch in the "on" state thereof and the ring-shaped actuator in the second position thereof. In a second alternative aspect of the invention, the switch arm may instead be movable between a first position operable to put the activator of the first switch in the "off" state thereof and the ring-shaped actuator in the first position thereof, a second position operable to put the activator of the first switch in the "off" state thereof and the ring- shaped actuator in the second position thereof, and a third position operable to put the activator of the first switch in the "on" state thereof and the ring-shaped actuator in the second position thereof. Either way, however, the switch arm is operable to put the first and second switches sequentially into the both "off", one "off" and one "on", and both "on" states, regardless of the angle of the switch arm relative to the rotation axis.
