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, 4, or 5 position selector, skip this step. (2, 4, 5 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
Caution: Before putting any custom selector switch into use, it should be tested using an ohmmeter.

If building a 3 position selector, determine appropriate cam as follows:
table. “L” and “R” refer to mounting on left or right side of operator as viewed from the front of the panel.
Look at Row 1 from above table and locate an identical row in the operator truth tables (See next page).
Repeat for all rows. Find one operator that contains all rows from above table.
Record the operator cam version.
