As a result, they can be safely cleaned of flux without fear of compromising operating characteristics. NKk's patented, award-winning STC contact mechanism offers benefits unavailable in conventional mechanisms. For example, mov- able twin contact surfaces pinch the stationary contacts to provide increased contact stability and unparalleled logic-level reliability. Continued reliability 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 previously unavailable in sliding contact type mechanisms. NKK* gwitches + 7850 E.
