Abstract
A switching element for a rotary or linear encoder which generates pulse signals indicative of rotary or linear position, and direction and rate of change of such position. The invention is characterized by use of a patterned and cured solder-mask material which defines insulated or nonconductive surfaces, with a pattern of conductive wiper-contacting segments therebetween. The invention enables fast and economical fabrication as compared to known encoder switching elements.
