1. Special use of 2 coil latching types: 2 
ways can be considered if 2 coil latching 
types are used as 1 coil latching types.
(A) Reverse polarity is applied to the set 
coil of 2 coil latching type.
(B) By shorting terminals 12 and 7, apply 
plus to 1, minus to 6 at set and plus to 6, 
minus to 1 at reset. Applied coil voltage 
should be the same as the nominal. 
Operating power will be reduced to one-
half.

Reset position of 2a2b type
