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:
●
●
10250T_
E34G_
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.

Note
Use NEMA 4X 10250T operators where exposed to ultraviolet light.
●
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.
