SymbolManual return (rotating direction)

Not indicated■Number of stages
Each units has 2 contacts. This means that the number ofunits is half of the total number of contacts.
However, if the handle is turned by 180 degrees or more,each units may not be including 2 contacts.

Manual return (axial direction)
Auto return (to neutral position)

Contact arrangement diagrams should be viewed from thepanel surface with the handle positioned below.
Vertical line shows notch positions, and horizontal line showsconnected circuits with terminal numbers. To enter the contact
symbols, follow the order of terminal numbers starting with thefront stage.

(5 notches at 45 degrees, 3 notches at 90 degrees or more)
A single cam actuates 2 contacts, upper and lower side.
Therefore, when the cam is rotated by 180 degrees or more,
its concavity to close either contact may also close the othercontact. In this case, the upper and lower contacts cannot
be combined freely.
