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.

The electrical specifications shown are determined at a basic temperature of 25°C.
LED circuit is independent of switch operation. LED is colored in OFF state.
If the source voltage is greater than the rated voltage of the LED, a ballast resistor must be connected in series with the LED.
The ballast resistor calculation and more lamp detail are shown in the Supplement section.
