Distinctive
Characteristics
Full face or spot illumination with incandescent lamps or multi-element LEDs,
with or without resistors.
Choice of super bright LEDs in white, green, and blue as well as bright LEDs
in red, amber, and green.
Combination bezel-barrier is an integral part of the switch and
prevents accidental actuation.
Unique thermoplastic elastomer seal inside caps plus
rolled sleeve of nitrile butadiene rubber at joining of
housing and inner case, all for added protection to
interior mechanism.
Dust and oil tight as well as splashproof panel seal
models qualify to IP65 of IEC60529 Standards (similar
to NEMA 4 and 13). Panel seal models provided
with exterior o-ring.
Distinctive design of snap-action contacts for shock
resistance, long life, and sensitive actuation.
High density design to give behind panel depth of less than
one inch.
Terminals are epoxy sealed to lock out flux, dust, solvents, and other
contaminants.
Latchdown for indication of circuit status, plus audible, tactile feedback
with smooth, responsive operation.
Matching indicators available.
