Distinctive Characteristics
B
Single unit construction of the flange and outer housing gives added
protection from environmental elements.
Specially designed contact mechanism for breaking
light welds.
Minimal contact bounce achieved with specially
designed interlocked switching mechanism.
Heat resistant resin used for outer housing,
inner case, and cover on wire lead models
meets UL94V-0 flammability standard and
provides high arc and tracking resistance.
Available with solder lug, screw, quick connect,
and wire lead terminations.
Sealed Construction Meets IP60 & IP67 Standards
Actual Size
Solder lug, screw, and quick connect terminal models
meet IP67 of IEC60529 Standards at front panel (dust
tight and water protected for temporary immersion,
patent pending). Behind panel standard is IP60 (dust
tight but not water protected).
Wire lead models conform fully to IP67 of IEC60529
Standards at front and behind panel (dust tight and
water protected for temporary immersion). Switch
base is epoxy sealed and covered by an outer case
for further protection from dust and water. (Switches
cannot be operated under water. Contact factory for
further details regarding operating environment.)
