Step 3: Cam Selection.
The cam you select
determines the operation of
all contact blocks mounted to
the operator. It is selected on
the basis that it provides the
simplest circuitry for the
desired “X-O” diagram. The
selection tables show all the
“X-O” combinations. For the
purpose of this example, the
applicable portion of those
tables is shown on this page.
Now to make the cam
selection, make a simple
worksheet such as below.
(1) or (2) = mounting location
from chart above:
X O O
O O X
It becomes obvious that
cam 3 is the better choice
because the series
connection can be avoided,
making it simpler to wire.
Step 4: Contact Block
Selection.
Having selected the cam,
contact block selection is
simply a matter of
determining if you require one
NO-NC contact block (Cat. No
10250T1H) or two. Given the
limitations of the factory
sealed contact block and the
desired “X-O” application,
you may have circuits that
will not be needed—as seen
here with the two additional
NC circuits. (1) or (2) =
mounting location from chart
above.

Step 5: Selector Switch
Operator.
Lastly, you have to choose
from the many types of
operators—knob and lever in
various colors or keyed. Also
what combinations of
maintained and spring return
functions are required.
Selection of these operators
can be found on Page 308.
For the example in step 4,
you may want a three-
position maintained black
knob, cam 3—Catalog
Number 10250T1323 (or
34VHBK1).
