Document Type and Number:
WIPO Patent Application WO2002093184
Kind Code:
A1
Abstract:
A switching element (10) for a rotary or linear encoder which generates pulse signals indicative of linear or rotary position, and direction , and rate of change of such position. The invention is characterized by use of a patterned and cured solder-mask (29) material which defines conductive (32), insulated or non-conductive surface (33), with a pattern of conductive wiper-contacting segments (31) there between. The invention enables fast and economical fabrication as compared to known encoder switching elements.
