Distinctive Characteristics
Environmentally friendly components and packaging materials meet RoHS Directive
restricting use of hazardous materials. Suited for lead-free soldering because of
heat resistant resin materials.
Smooth, slightly concave surface of cap designed to
fit fingertip. Unique design and construction of cap
D
prevents its removal and limits tampering.
Bright LED illumination in choice of red, green
or amber through translucent white cap. Spot
illumination in red, green or amber enhanced
by black cap.
Short body of .551 (14.0mm) conserves behind-
panel space.
Installation options include 16.0mm bushing mount or
17.3mm snap-in mount.
Combination solder lug and .110 quick connect
terminals are epoxy sealed to prevent entry of flux, dust,
or other contaminants.
Crisp actuation and clear circuit status provided by snap-action
contact mechanism. Arc barrier between movable contacts protects
against crossover.
