Snap-Action Pushbuttons Series MB2400

Distinctive Characteristics

Snap-acting mechanism gives smooth actuation, short stroke,

light touch, and audible feedback. This mechanism also provides

long mechanical life.

High torque bushing construction prevents rotation or separation

from frame during installation.

Antijamming design protects contacts from damage due to

excessive downward force on the actuator.

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.

Longer center solder lug terminal simpliﬁes wiring and

soldering.

Silver contacts of specially composed alloy for hardness.

Epoxy sealed terminals prevent entry of solder ﬂux and other

contaminants.

Prominent external insulating barriers increase insulation resistance

and dielectric strength.
