Circuitry |
Contact arrangement
available in choice of single pole double throw (SPDT)
or single pole single throw (SPST), either normally
open (NO) or normally closed (NC).
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:
E19-00A is double throw
E19-01A is normally open
E19-02A is normally closed

the current rating you need. Combine the corresponding
Series/Prefix number with the appropriate suffix number
for the switch type, circuitry and terminals you require.
(see Actuator Specifications table above).
Example:
E19-01A = 15A, DPST NO, with no actuator
E20-50K = 20A, DPDT, with .902" roller
