The E34 Series 30.5 mm pushbutton line
features the same rugged die cast
construction of our 10250T line with an
additional two layer 100% solid thermosetting
cathodic epoxy coating. This coating provides
a flat black smooth, consistent, corrosion
resistant surface that has passed a demanding
600 hour salt spray test. (The industry
standard for this 4X test requires only
200 hours). E34 cathodic coating is not
recommended for use in applications where
exposure to ultraviolet light exists—use
NEMA 4X 10250T operators.
The 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.
The E34 Series 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.
