This application is a Continuation of U.S. patent application Ser. No. 13/964,046, filed Aug. 10, 2013, now U.S. Pat. No. 9,015,887, which is a Continuation of U.S. patent application Ser. No. 13/888,140, now U.S. Pat. No. 8,528,142, filed May 6, 2013, which is a Continuation of U.S. patent application Ser. No. 13/554,593, now U.S. Pat. No. 8,438,685, filed Jul. 20, 2012, which is a Divisional of U.S. patent application Ser. No. 11/868,353, now U.S. Pat. No. 8,245,345, filed Oct. 5, 2007, which is a Continuation of U.S. patent Ser. No. 11/059,663, now U.S. Pat. No. 7,533,435, filed Feb. 15, 2005, which claims the benefit of U.S. Provisional Patent Application Ser. Nos. 60/545,153 and 60/627,606, filed Feb. 16, 2004 and Nov. 12, 2004, respectively, and which is a Continuation-In-Part of abandoned U.S. patent application Ser. No. 10/737,027, filed Dec. 15, 2003, which is a Continuation-In-Part of abandoned U.S. patent application Ser. No. 10/438,485, filed May 14, 2003, the entire disclosures of which are incorporated by reference in their entirety herein.
It is likewise known that a throttle used on an electric motor drive device could operate by switches which regulate power delivered from batteries to a motor. For instance, and referring now to FIG. 10 from incorporated by reference U.S. Pat. No. 4,196,492: “batteries 240 are connected through a manually operable switch 117 to a solenoid operated switch 134. Switch 134 has two sets of normally open contacts 132 and two sets of normally closed contacts 133. All the contacts 132 and 133 are mechanically coupled together by means of a rod 135 for simultaneous ganged operation when coil 136 is energized. In the operation of cleaning machine 202, when the manually operable switch 117 is closed by the operator, coil 136 is energized causing the contacts 132 to close. This feeds power through to a potentiometer 131. Potentiometer 131 may be used to vary the voltage there through to adjust the speed of drive motor 108. From the potentiometer 131, the power passes through a forward and reverse switch 120. Forward and reverse switch 120 is identical to that disclosed in FIG. 7 and has for its purpose the changing of the polarity of the voltage applied to drive motor 108 to drive that motor in forward or reverse directions. However, indicator lights generally indicated as 260 and 262 are wired into the forward and reverse switch 120. When the motor 108 is being driven in a forward direction, the green indicator light 260 will light. Conversely, when the motor 108 is being driven in a reverse direction, the red indicator light 262 will be lit.”
