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.  
D
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.

Bicolor  
The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and requires  
external power source. Single color LEDs are colored in OFF state. Bicolor LED is translucent white in OFF state.  
If the source voltage exceeds the rated voltage, a ballast resistor is required.  
The resistor value can be calculated by using the formula in the Supplement section.
