Thanks for the part number suggestion. Switch part numbers are always fun to look through because there are a million different configurations. Honeywell's document about the TL series is no different.
Most likely I will simplify this to separate switches, but anywhere that I do use a 3-position switch, I now know that there are lockout switches available to use.
