Circuitry — Single Pole
Contact arrangement available in choice of
single pole double throw or single pole sin-
gle throw, either normally open or normally
closed. In general, normally open may be
specified by changing suffix number from
00 to 01 and normally closed by changing
suffix number to 02.
Example: E13-00E is double throw,
E13-01E is normally open, and E13-02E
is normally closed.
