1. NKK s patented award winning STC contact mecha nism offers benefits unavailable in conventional mech anisms The movable twin contact surfaces pinch the Stationary contacts to provide increased contact stabil ity and unparalleled logic level reliability Continued re liability is assured since the gold plated contacts are wiped clean with each actuation Furthermore if one side of the twin contacts should fail to conduct the other side functions as a backup or fail safe path for the current The combination of rounded movable and stationary contacts provides smooth contact feel previ ously unavailable in sliding contact type mechanisms K D 38E EE b42877b 0001919 b74 EE l switches 7850 E Gelding Dr Scottsdale AZ 85260 Phone 602 991 0942 Fax 602 998 1435 Copyright Each Manufacturing Company All Datasheets cannot be modified without permission This datasheet has been download from www AllDataSheet com 100 Free DataSheet Search Site Free Download No Register Fast Search System www AllDataSheet com
