Series M2 Process Sealed Miniature Pushbuttons s e Distinctive Characteristics gl g o T s Snap-acting contact mechanism gives short travel, sensitive actuation, ker c o light touch, smooth feel, audible feedback, and a longer electrical life. R s n o C utt b Single unit construction of the bushing and top of the sh u P housing gives protection from cleaning fluids or B other liquids. d P e at n mi u Ill e O-ring surrounding actuator at top of bushing bl a interior prevents liquids from reaching switch mm a mechanism. gr o Pr s k c o Ultrasonic welding of upper and lower eyl K housing seals out contaminants and allows automated soldering and cleaning. s e ari ot R Terminals are epoxy sealed to prevent entry of flux, solvents, and other contaminants. es d Sli s Bracketed models have crimped bracket legs to e ensure secure PC mounting and prevent dislodging actil T during automated soldering. Tilt Logic level and power capabilities are available to suit varying applications. Actual Size ch u o T s or at c di n I s e ori s s e c c A nt e m e pl p u S www.nkkswitches.com C65
