Miniature Pushbuttons Series MB2000
Distinctive Characteristics
Guide interlocked with actuator block prevents window locking and
maintains correct plunger alignment to assure contact stability.
Employs an over-center actuator mechanism, which diminishes
sparking and increases operating life in AC circuits.
High torque bushing construction prevents rotation
or separation from frame during installation.
Splashproof option (D3 and B3 bushing codes) features an
o-ring within the bushing and one under the face nut
to protect from splashed, sprayed, or spilled liquids.
High insulating barriers, formed in the molded
diallyl phthalate case, increase isolation of circuits
in multipole devices.
Prominent external insulating barriers increase
insulation resistance and dielectric strength.
Epoxy sealed terminals prevent entry of solder
flux and other contaminants.
Clinching of the frame to the case well above the base
and terminals provides 1,500V dielectric strength.
