A82 www.nkk.com A Rockers Distinctive Characteristics Toggles Series M2 Process Sealed Miniature Toggles Pushbuttons Antijamming actuator design protects against mechanism damage from downward force on the toggle. Programmable Illuminated PB Single unit construction of the bushing and top of the housing gives protection from cleaning fluids orother liquids. Keylocks O-ring surrounding actuator at top of bushing interior prevents liquids from reaching switch mechanism. Rotaries Ultrasonic welding of upper and lower housing seals out contaminants and allows automated soldering and cleaning. Slides Terminals are epoxy sealed to prevent entry of flux, solvents, and other contaminants. Tilt Tactiles Bracketed models have crimped legs to ensure secure PC mounting and prevent dislodging during automated soldering. Touch Logic level and power capabilities are available to suit varying applications.
