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.
