ER421 Overview
The magnetic-latching TO-5 relay, originally conceived and developed by Teledyne, has bee 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 most versatile ultraminiature relays available. The following unique construction.
