Abstract
A switching device includes the ability to perform a primary and secondary switching function through the use of a single switch handle. A primary switch contact is activated when the switch handle is moved in a desired direction. A secondary switch contact is activated when the switch handle is further moved in the same direction. The secondary switch contact includes a generally flexible conductive member supported adjacent a printed circuit board. An actuator portion of the switch handle moves into contact with the generally flexible conductive member causing a central portion of that member to flex toward and contact the printed circuit board. Such electrical contact results in a signal being generated that is indicative of a desire to accomplish the secondary switching function.
