To build a custom selector switch, follow these steps.
Step1: 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)
Step 5: Build by placing appropriate contact in appropriate mounting position for each desired row on operator cam truth
Step 6: Develop an assembly part number (if necessary) as follows: follow standard numbering nomenclature for selector
Caution: Before putting any custom selector switch into use, the user should use an ohmmeter to test

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