NKK EB2085G-BH Light touch miniature pushbutton Datasheet

Light Touch Miniature Pushbuttons
Series EB
Distinctive Characteristics
Power and logic level capabilities available to suit varying applications.
Bushing and snap-in mount versions available; snap-in models offer
many style and color choices to enhance front panel appearance.
Light touch actuation.
High torque bushing prevents rotation and separation from
metal frame during installation.
Stainless steel frame resists corrosion.
Case of heat resistant resin meets UL 94V-0 flammability
rating.
Higher insulating barriers protect against crossover in
double pole devices.
1,500V dielectric strength between contacts and case
is accomplished by clinching the frame away from the
terminals.
Epoxy sealed terminals prevent entry of solder flux and
other contaminants.
