Pushbuttons and Indicating Lights
30.5 mm Corrosion Resistant Watertight/Oiltight—E34
Product Overview
Ultraviolet Light
E34 cathodic coating is not
recommended for use in
applications where exposure
to ultraviolet light exists—use
NEMA 4X 10250T operators.
Reliability Nibs
Eaton’s contact blocks
feature enclosed silver
contacts with pointed
“reliability nibs” for reliable
performance from logic level
up to 600V. To ensure reliable
switching, nibs bite through
oxide which can form on silver
contacts, eliminating the
need for expensive logic level
blocks for most applications.

Diaphragm Seal with
Drainage Holes
Liquid Drainage
Eaton’s pushbutton operators
offer front of panel drainage
via holes in the operator
bushing. Hidden from view by
the mounting nut, these
holes prevent buildup of liquid
inside the operator, which
can prevent operation in
freezing environments. The
holes also provide a route for
escaping liquid in high
pressure washdowns,
effectively relieving pressure
from the internal diaphragm
seal, ensuring reliable sealing
in applications even beyond
NEMA 4.
