Product Description
The 30.5 mm pushbutton line features
a zinc die cast construction with
chrome-plated housing and mounting
nut. The same durable construction is
also available with the corrosive resis-
tant E34 line of pushbuttons. See E34
section on Pages 47-166 – 47-189.
Reliability Nibs
Eaton’s Cutler-Hammer
blocks feature enclosed silver contacts
with pointed “reliability nibs” for reli-
able 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.
Figure 47-90. Reliability Nibs
Reliability nibs improve performance
in dry circuit, corrosive, fine dust and
other contaminated atmospheres.
Under normal environmental condi-
tions, the minimum operational voltage
is 5V and the minimum operational
current is 1 mA, AC/DC. For operation
under a wider range of environmental
conditions, logic level contact blocks
with inert palladium tipped contacts
are recommended.

Grounding Nibs
10250T line operators have “grounding
nibs” — four metal points on the oper-
ator casting designed to bite through
most paints and other coatings on
metal panels to enhance the ground
connection when the operator is
securely tightened.
Diaphragm Seal with Drainage Holes
Liquid Drainage
Eaton’s Cutler-Hammer pushbutton
operators offer front of panel drainage
via holes in the operator bushing. Hid-
den 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 wash-
downs, effectively relieving pressure
from the internal diaphragm seal,
ensuring reliable sealing in applica-
tions even beyond NEMA 4.
