To build a custom selector switch, follow these steps.
Step 1
How many positions of the switch are needed?
Step 2
How many contacts should there be?
Step 3
Fill in the Truth Table
Step 4
If building a 2 position selector, skip this step. (2 position selectors have only one cam)
If building a 3, 4, or 5 position selector, determine appropriate cam as follows:
Step 5
Build by placing appropriate contact in appropriate mounting position for each desired row on operator cam truth table. “L” and “R” refer to mounting on left or right
side of operator as viewed from the front of the panel.
Step 6
Develop an assembly part number (if necessary) as follows: follow standard numbering nomenclature for selector switches (see pages 577 or 581. In place of the
“Circuit Number” indicate the cam number and contact arrangement as such ASW322-3-OELCSS, where “3” is the cam number, and contact arrangement “OELCXX”
calls out individual contact mounting locations in order (see diagram above). O=NO, C=NC, E=NO-EM, L=NC-LB, X= no contact. Part number must designate all 6 pos-
sible mounting locations.
(X = closed, 0 = open)
# of isolated contacts
Caution: Before putting any custom selector switch into use, the user should use an ohmmeter to test for desired performance.

Look at Row 1 from above table and locate an identical row in the operator truth tables (See next page).
Repeat for all rows. The user must fi nd one operator that contains all rows from above table.
Record the operator cam version.
