SCHEMATIC
1. Single side stable (2, 6: free terminals)
2. Latching type
1. The latching type of R relay can be
used as the memory element to be
operated by a pulse supplied from one or
two different sources.

Operating function
“Getter” hole
Same operation as the conventional magnetic relays.
(a) During deenergization, terminals No. 4 (COM) and
Once energizaed, the COM contact is kept under the
same condition without further energizing continuously.

(a) When terminals No. 5 (+) and No. 6 (–) or
No. 1 (N.C.) are on “make”.
energized, terminals No. 4 and No. 7 are switched
to “make”. (or stay on “make”). when the coil
current is switched off, terminals No. 4 and No. 7
are held on “make.”
terminals No. 3 (+) and No. 2 (–) are energized
terminals No. 4 and No. 7 are switched to “make”.
(or remain on “make”). When the coil current is
switched off, these terminals are held on “make”.
Structure
Special use of 2 coil latching
2 coil latching can be used in the same manner as 1
coil latching by shorting No. 5 and No. 2 or No. 3
and No. 6

2. With the 2 coil latching type, when
simultaneously applying one polarity to
one coil and the opposite polarity to the
other, the previously energized coil will
take priority of operation and will
maintain the contact condition.

recommendable.
“Getter” holes are formed on both pole
shoes to obtain uniform contact
resistance throughout life. Film-forming
phenomena on contacts is thus fully
prevented.
