RY2KS Series Latch Relays
Self-maintained Latch Relays
DPDT — 3A contact capacity
The RY2KS series latch relays have a self-holding function using permanent magnets in the magnetic circuit. Applying a voltage Switches & Pilot Lights
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 fl ip-fl op circuit applications.

Notes:
1. 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. Terminal Blocks
