Wire lead models conform fully to IP67 of IEC60529 Standards
at front and behind panel (dust tight and water protected for
temporary immersion). These models are epoxy sealed at the
switch base and covered by an outer case for further protection
from dust and water (not operable under water).
Slides
Solder lug and screw terminal models meet IP67 of
IEC60529 Standards at front panel (dust tight and
water protected for temporary immersion). Behind
panel standard is IP60 (dust tight but not water protected).
