Circuitry
Contact arrangement available in choice of single pole
double throw or single pole single 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.
Note:
0.187'' Quick Connect terminals are standard.
Normally, to order screw terminals add 10 to suffix number.
To order solder terminals add 20 to suffix number and to
order 0.250" Q.C. terminals add 40 to suffix number.
