ER421D, ER421, Relays

The magnetic-latching TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards for low-level switching from dry circuit to 0.5 ampere.

Designed for high-density PC board mounting, its small size and low coil power dissipation make the 421 relay one of the
