Series WT
Environmentally Sealed Toggles
Distinctive
Characteristics
A
Sealing for wire lead models meets IP67 of IEC60529 Standards
at front and back panel.
Sealing for solder lug or screw lug models meets IP67
at front panel and IP60 at back panel.
Single unit construction of bushing and case gives
added protection from environmental elements.
Epoxy sealed base covered by outer case doubles
protection from dust and water (not operable under
water or oil).
Specially designed contact mechanism that breaks
light contact welds for circuits 11, 12, 21 and 22.
Interlocked movable contact mechanism provides
highly reliable switching by minimizing contact
bounce over center contact.
Actual Size
Heat resistant resin used for outer housing meets UL94V-0
flammability standard and provides high arc and tracking
resistance.
