Circuitry

This series is available in single pole double throw (SPDT) and single pole single throw (SPST) either normally open (NO) or normally closed (NC).

In general, normally open may be specified by adding 01 to suffix numbers, and normally closed by adding 02.

For example:
E51-00B is double throw,
E51-01B is normally open and
E51-02B is normally closed.
