Series MB2400 Snap-Action Pushbuttons s e Distinctive Characteristics ggl o T s er k Snap-acting mechanism gives smooth actuation, short stroke, oc R light touch, and audible feedback. This mechanism also provides long mechanical life. s n o C utt b h High torque bushing construction prevents rotation or separation s u P from frame during installation. B P d e at Antijamming design protects contacts from damage due to n mi excessive downward force on the actuator. Illu e bl a m Compatible companions with M series toggles. Body, m a bushing, and footprint dimensions ideal for mounting gr o MB2400 pushbuttons and M toggles next to one another. Pr s k c o Stainless steel frame resists corrosion. yl e K Longer center solder lug terminal simplifies wiring and s e soldering. ari ot R Silver contacts of specially composed alloy for hardness. s e d Epoxy sealed terminals prevent entry of solder flux and other Sli contaminants. s e Prominent external insulating barriers increase insulation resistance ctil a T and dielectric strength.
