C96 www.nkk.com Toggles Series MB2400 Rockers Distinctive Characteristics Snap-acting mechanism gives smooth actuation, short stroke, light touch, and audible feedback. This mechanism also provides long mechanical life. C Programmable Illuminated PB High torque bushing construction prevents rotation or separation from frame during installation. Pushbuttons Snap-Action Pushbuttons Antijamming design protects contacts from damage due to excessive downward force on the actuator. Keylocks Compatible companions with M series toggles. Body, bushing, and footprint dimensions ideal for mounting MB2400 pushbuttons and M toggles next to one another. Stainless steel frame resists corrosion. Rotaries Longer center solder lug terminal simplifies wiring and soldering. Slides Silver contacts of specially composed alloy for hardness. Tactiles Epoxy sealed terminals prevent entry of solder flux and other contaminants. Tilt Prominent external insulating barriers increase insulation resistance and dielectric strength.
