INTERACTIVE INPUT SYSTEM AND PEN TOOL THEREFOR

摘要

A pen tool for use with an interactive input system comprises an elongate body, at least one switch assembly accommodated by the body and a controller accommodated by the body and communicating with the at least one switch assembly. The at least one switch assembly is actualable when the pen tool is brought into contact with an input surface of the interactive input system. The controller is responsive to actuation of the at least one switch assembly. The at least one switch assembly comprises a contact circuit and a plunger assembly having a conductive element thereon that is generally aligned with the contact circuit. The plunger assembly is moveable into the body to bring the conductive element into contact with the contact circuit thereby actuate the at least one switch assembly.
