Roto-Push Operators
Roto-Push Components
A Roto-Push control unit
combines the function of a
pushbutton and a selector
switch. The contacts are
operated by the combined
action of rotating the outer
collar and pushing a button
contained in the collar.
In selecting the cam and
contact blocks for the listed
function, the analysis involves
considering the function with
the collar rotated to the given
position with the button free
(designated as “N”) and then
in that same position with
the button depressed
(designated “D”). This is done
for each rotational position of
the collar.
When Ordering Specify
●
Catalog number of
operator with cam code
suffix from tables below
and on following pages,
Example: 10250T2411.
●
Catalog number(s) for
contact blocks and legend
plates if required.
●
To select the cam and
contact blocks needed for
two-position and three-
position switches, use the
tables on following pages.
Operator and Cam
Two-Position Roto-Push Operator—Rotates to a Latch-Out Mode
Special Rotor Latch
This differs from the other
Roto-Push operators in that
as the collar is rotated to the
right it depresses the button
and releases the button when
rotated left. But the button in
the released position can be
momentarily pushed
independent of the collar or
its position. As the button is
depressed by rotating the
collar, the button also rotates
and indicates its mode by a
white line on the button face.
This button can be used as an
emergency stop or latched
stop.

UL (NEMA) Type 3, 3R, 4, 4X, 12, 13

Not to be used for emergency stop application.
