potential)  

The Type 3SBM relay adds  

magnetic latching capability  

to the popular and growing  

family of .150-grid relays.  

This relay has memory in  

that the contact positions do  

not change when coil power  

is removed. Switching is  

accomplished by applying  

power to the applicable coil  

(dual coil) or with the appli-  

cable polarity (single coil).  

The low switching power  

requirements are further  

enhanced by its ability to  

operate from capacitor dis-  

charge or other pulses or  

through its own contacts  

from batteries or similarly  

limited supplies.

When the SET coil is pulsed  

with plus polarity on the blue  

bead, the movable contacts  

take the position shown in the  

connection diagram. The con-  

tacts are transferred when the  

RESET coil is pulsed with plus  

polarity on the reset terminal. A  

new pulse of the SET coil with  

plus polarity on the blue bead  

will transfer the contacts back.  

The contacts can also be trans-  

ferred by applying a pulse of  

opposite polarity to the coil pre-
