Miniature Rockers
Series M
Distinctive Characteristics
Three methods of panel mounting: flat frame for flush with face or subpanel,
snap-in, and PCB.
High insulating barriers increase isolation of circuits in multipole devices
and provide added protection to contact points.
The molded diallyl phthalate case has a UL 94V-0
flammability rating.
Epoxy sealed terminals prevent entry of solder flux
and other contaminants.
Prominent external insulating barriers increase
insulation resistance and dielectric strength.
Bias guard prevents misalignment of contacts;
interlocking of actuator block with rocker and
internal guide does not allow transmission of
diagonal force on rocker to reach contact
mechanism.
Clinching of the frame to the case well above the base and
terminals provides 1,500V dielectric strength.
