Push-Pull Operators
An illuminated push-pull
pushbutton unit, arranged for
one-hole mounting, can
replace two pushbuttons and
a pilot light or the non-
illuminated form can replace
two pushbuttons. These units
are available in three basic
types:
●
●
Two-Position Maint.
Push-Pull
Maintained—(Two-
position). Maintains in the
pulled or pushed position
until manually actuated to
the opposite mode.
Momentary—(Three-
position). Spring returns to
an intermediate position
when pulled or pushed and
released.

Notes
Use NEMA 4X 10250T operators where exposed to ultraviolet light, see Pages 140–212.
See Typical Applications on Page 162.
E34GHB.
Shown without button on lens.
Maximum of two blocks, four circuits. Special function contact blocks shown on Page 245 CANNOT be used with three-position push-pull operators E34GEB, E34GFB or
●
The operators, buttons,
contact blocks, etc., are
offered as building block
components that can be
intermixed to satisfy many
requirements. This minimizes
the need for a varied and
costly inventory.
Momentary Pull,
Maintained Push—(Three-
position). Spring returns to
intermediate position when
pulled. Maintains in pushed
position until manually
returned to intermediate
(ready to reset) position.
Maintained stop holds
circuit open and will
prevent other series
connected operators from
starting the system.

Application Guide
To assist in the selection of
contact blocks, the sketch
below shows pictorially by
symbols A and B locations of
contact circuits after
assembly of contact blocks
and adapter to the operator.
The table below shows the
effect of the push and pull
operations on either NO or
NC contacts. (X = contact
closed, O = contact open).
