Abstract
An encoder device coupled to a roller or “scroll wheel” includes a mechanism to convert a rotating movement of the roller into a reciprocating movement that causes intermittent electrical conduction between two metal contacts so as to output an intermittent electrical signal indicative of roller movement without continuous power consumption.
