Applying a voltage on the set (or reset) coil operates the armature and retains the contacts in that position until the opposite coil is energized, hence the latch relays are ideal for memory and ip- op circuit applications.

For the relays with check button, use the parenthesized hold-down springs shown in the above table. When the spring is used, sockets cannot be mounted closely side by side. 2. Use the hold-down springs in environ- ments where the relays are subject to vibrations or shocks.
