Distinctive Characteristics
Antirotation design, standard on noncylindrical levers, mates toggle
and bushing; bottom of toggle has two flatted sides which fit into
a complementary opening inside bushing.
Antijamming design protects contacts from damage due
to excessive downward force on actuator.
High torque bushing construction prevents rotation
or separation from frame during installation.
High insulating barriers increase isolation of
circuits in multipole devices and provide
added protection to contact points.
Molded diallyl phthalate case has a UL
flammability rating of 94V-0.
Epoxy sealed terminals prevent entry
of solder flux and other contaminants.
Prominent external insulating barriers
increase insulation resistance and
dielectric strength.
Interlocked actuator block, lever, and interior guide
prevent switch failure due to biased lever movement.
Clinching of frame to case well above base and terminals
provides 1,500V dielectric strength.
