Selector Switch Selection Guide
Shown below is a simplified method of selecting a selector
switch to meet almost any combination of contact sequences.
Step No. 1
Determine the contact sequence(s) required. Set up a target ta-
ble like the one shown for the example below.
Example:
Step No. 2
Look for a cam type common to all sequences in Table 1, 2 or
3. For the example above, Table 2 would be used. For the con-
tact sequences A(1 0 0), B(0 1 0) and C(0 0 1) of the example
above, cam types F and L are common to all 3 sequences.
Step No. 3
Next, the cam type common to all the sequences (If several
cam types are common, choose one.) is used to find the oper-
ator type number. Go to the proper page number as indicated
in the table below:
If for the example above:
A manual return operator with a standard black knob is required and
Step No. 4:
Determine the contact blocks required by using the same table
used for Step No. 2.
If for the example above:
The F cam type were chosen:
The L cam type were chosen:
One Type KA1 double circuit block can be used in place of one
Type KA2 single circuit block and one Type KA3 single circuit
block mounted on the same side.

Number of Positions
If the F cam type were chosen, the operator type number would be:
If the L cam type were chosen, the operator type number would be:
A 9001KA3 mounted on side no. 2 would be used for sequence A(1 0 0).
A 9001KA3 mounted on side no. 1 would be used for sequence B(0 1 0).
A 9001KA2 mounted on side no. 1 or 2 would be used for sequence
C(0 0 1).
A 9001KA2 mounted on side no. 2 would be used for sequence A(1 0 0).
A 9001KA2 mounted on side no. 1 or a 9001 KA3 mounted on side no.
2 would be used for sequence B(0 1 0).
A 9001KA3 mounted on side no. 1 would be used for sequence C(0 0 1).

The KA5 must be the last block on either side. If more than one KA5 is required on either
side – contact your local Square D sales office.
