Abstract
The present invention provides a rotating dual switching mechanism having a first switch and a first activator with rotational axis, and a second switch having a second activator that is offset from the rotational axis. A ring-shaped actuator is concentric with the rotational axis and is movable to actuate the second activator. A switch arm is rotatable about the rotation axis and has a first portion that actuates the first activator and a second portion for engaging and the ring-shaped actuator and hence the second activator. The switch arm is movable to a first position where both the first and second activator are “off,” a second position where the first activator is “on” and the second activator is “off,” and a third position where both the first and second activator are “on.”
