Specially designed contact mechanism for breaking light welds.
Minimal contact bounce is achieved with specially
designed interlocked switching mechanism.
Outer housing of heat resistant resin meets UL 94V-0
flammability standard and provides high arc and
tracking resistance.
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).
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).
